How to choose and use scissors for cutting polypropylene pipes

[ad_1]

Plas­tic pipes are active­ly replac­ing met­al coun­ter­parts from the build­ing mate­ri­als mar­ket. The advan­tage of plas­tic will be its light­ness, ease of oper­a­tion, the abil­i­ty to install it your­self, resis­tance to cor­ro­sion. To work, you do not need spe­cial tools, it is impor­tant to have scis­sors for cut­ting. They make it pos­si­ble to make an even cut, spend­ing a min­i­mum amount of time. Depend­ing on the con­di­tions of use and the inten­si­ty of work, var­i­ous types of tools are used.

How to choose scissors for cutting polypropylene pipes

Prod­uct selec­tion

In order for the prod­uct to be used to the max­i­mum for a long time, when buy­ing a tool, empha­sis is placed on the fol­low­ing char­ac­ter­is­tics:

  • Blade. Made from stain­less steel. The empha­sis is on sharp­en­ing. To achieve an effec­tive cut, the angle is 30 degrees.
  • Han­dle. So that in the process of work­ing with the device you do not feel fatigue and incon­ve­nience, you must ini­tial­ly care­ful­ly exam­ine the han­dle of the prod­uct. It is opti­mal to pur­chase prod­ucts with rub­ber han­dles.
  • Pipe sup­port. Such a part must be wide so that the cut­ting of met­al-plas­tic occurs at an angle of 90 degrees. When pipe rolling is not secure­ly sup­port­ed by scis­sors, they should not be pur­chased.
  • Reverse auto-retrac­tion. When the prod­uct remains closed after com­pres­sion, the device will be uncom­fort­able when cut­ting dif­fer­ent frag­ments of the part. There­fore, you should buy a mod­el with auto-retrac­tion to the start­ing posi­tion.
  • Retain­er. Find­ing a device with­out a latch is now dif­fi­cult, but the selec­tion process needs to focus on this, since there are prod­ucts with­out it.

Impor­tant! When you need to cut small parts, there is no need to pur­chase large scis­sors for cut­ting plas­tic pipes. How­ev­er, when the device is used reg­u­lar­ly, bud­get seg­ment mod­els are not rec­om­mend­ed.

The device device and the principle of its operation

Such a tool is con­sid­ered man­u­al and is used in plumb­ing instal­la­tion work for water sup­ply and the cre­ation of heat­ing sys­tems. The blanks are pre-cut before work.

The plumb­ing mod­el will pro­vide the great­est force that falls on the cut­ting edge. Scis­sors that cut plas­tic pipes are con­sid­ered a com­plex design, which is why the han­dle can be squeezed in one hand.

The device is select­ed tak­ing into account the diam­e­ter of the part to be cut, start­ing from the design fea­tures. For exam­ple, it is pos­si­ble to choose pipe shears sim­i­lar to ordi­nary ones for the home. They are used for prod­ucts in 0.5, 1 and 2 inch­es. One side of the device is equipped with a com­fort­able han­dle, and the oth­er side is equipped with a pro­file in the form of the let­ter “V”.

Oper­at­ing prin­ci­ple

To car­ry out the cut, scis­sors for cut­ting pipes made of polypropy­lene are brought close to the prod­uct from below. In view of this, it is pos­si­ble to cut the work­piece into iden­ti­cal frag­ments that dif­fer in diam­e­ter. The char­ac­ter­is­tic fea­tures of the cut­ting scis­sors design facil­i­tate quick replace­ment of blades when the need aris­es.

Varieties of scissors

*

There are dif­fer­ent shears for met­al-plas­tic pipes, which dif­fer in device, prin­ci­ple of oper­a­tion and scope. The mod­els used at home dur­ing repairs are man­u­al­ly con­trolled and are inex­pen­sive. Devices that are designed for cut­ting heat­ing pipes are dri­ven by an elec­tric dri­ve.

Precision scissors

Pre­ci­sion scis­sors

This kind of device is sim­ple. The user will use only 1 hand, which will facil­i­tate the work. The main task of such a device will be cut­ting pipes made of polypropy­lene and plas­tic, with a diam­e­ter in the range of 3–40 mm. Spe­cial mod­els are avail­able for sale, suit­able for rolled pipes up to 75 mm in diam­e­ter.

The knife is made of spe­cial steel, which will give aux­il­iary strength. Its sharp­en­ing will guar­an­tee an opti­mal cut. The ratch­et attach­ment is ide­al for house­hold use.

The device is also suit­able for met­al-plas­tic pipe rolling. The main dif­fer­ence will be the mate­r­i­al of the cut­ter. The device, which is designed for parts made of poly­mers, is dis­tin­guished by steel with fine teeth (pro­vide a tight grip).

The selec­tion focus­es on:

  • blade sharp­ness and replace­ment options when it is intend­ed to be used for a cer­tain peri­od of time;
  • con­ve­nience at work: smooth run­ning (some­times rubs the palm under mechan­i­cal load) and com­fort of loca­tion (no slip).

Roller pipe cutter

The sim­plest types look like a hook, inside of which there are spe­cial rollers. When cut­ting, the pipe will rotate along such struc­tur­al ele­ments, as a result of which a cut will occur. The spring and the force that is applied by hand will ensure the move­ment of the cut­ter.

The dif­fer­ence from the pre­vi­ous vari­ety will be the par­tic­i­pa­tion of 2 hands, since it is required to sup­port an addi­tion­al valve that extends the knife. Such a device care­ful­ly cuts and slight­ly com­press­es a polypropy­lene pipe, like oth­er prod­ucts.

The cut­ter is con­sid­ered replace­able, because it can be used for a long time. The main dif­fi­cul­ty when cut­ting will be the need to hold the tool per­pen­dic­u­lar. When such a require­ment is vio­lat­ed, the knife becomes defec­tive.

The bat­tery pow­ered tool is an improved ver­sion of the hand held tool. The user who per­forms the pro­ce­dure does not need to apply force, since the knife and fix­ing ele­ments are bat­tery pow­ered.

A pipe cut­ter with an elec­tric motor pro­vides the max­i­mum even cut and is char­ac­ter­ized by a high speed of work. In view of this, the device is con­sid­ered a spe­cial­ized tech­nique. Scis­sors are used by work­ers to lay long lines for sup­ply­ing water or heat­ing.

Their appli­ca­tion is sim­ple: a sec­tion of the pipe-roll to be cut is placed in the spe­cial fix­a­tor, then the engine is acti­vat­ed, after the work is com­plet­ed. The dis­ad­van­tages include the high price in com­par­i­son with prod­ucts for cut­ting plas­tic pipes by hand.

cord­less scis­sors

Ratchet

This vari­ety is con­sid­ered the best ver­sion of the roller tool. The mech­a­nism helps to use the prod­uct more com­fort­ably, no spe­cial efforts are required. This is due to the pres­ence of a spe­cial rail.

The sup­port in the device is wide, it is nec­es­sary to secure­ly fix the knee (there is no need to con­trol the posi­tion of the pipe cut­ter).

The pres­ence of a stop reduces the risk of a sud­den change in loca­tion, the appear­ance of defects. The blade of the scis­sors is extreme­ly sharp, which will allow the prod­uct to glide smooth­ly.

Ratch­et

Guillotines and pipe cutting machines

To pro­fes­sion­al­ly assem­ble plumb­ing and heat­ing sys­tems, hand tools will not help, because they do not have accu­ra­cy and require effort. Work­shops are equipped with guil­lotines: a sharp cut­ter is direct­ed over a pipe fixed in a vice. The force is formed by an elec­tric or mechan­i­cal motor, which will mul­ti­ply the user’s efforts.

The defor­ma­tion of the wall is pre­vent­ed by blanks insert­ed in advance into the inci­sion node. In large fac­to­ries, the process is brought to automa­tism, and the saw cut is con­trolled by elec­tron­ics. After the pipe rolling, you do not need to clean it before instal­la­tion: the cuts made by hand need to be sand­ed.

In spe­cial stores it is pos­si­ble to choose dif­fer­ent mod­els, with dif­fer­ent para­me­ters and cost. Before mak­ing a pur­chase of a prod­uct, you need to study the instruc­tions for each mod­el and read the reviews. This will great­ly sim­pli­fy the choice. The best scis­sors:

  • PPC42 FIRAT. Used for instal­la­tion work equip­ment that reg­u­lates the cli­mate in the home. The device is suit­able for cut­ting pipes with a diam­e­ter of 20 — 40 mm with an opti­mal­ly even cut.
  • A guil­lo­tine that is used to cut plas­tic pipes with a small diam­e­ter of 30 mm. The tool has a ratch­et mech­a­nism that pro­vides cut­ting of high qual­i­ty plas­tic. Using this mod­el, there is no need to dis­con­nect the rail sup­port, since the device has a spring that rotates the parts of the prod­uct to the ini­tial posi­tion.
  • Polypropy­lene pipe shears have a ratch­et mech­a­nism, have a com­bi­na­tion of low cost and high qual­i­ty. Suit­able for pipes with a diam­e­ter of up to 4.2 cm. The kit comes with a sharp knife that pro­vides an even cut. There is 1 draw­back — a met­al han­dle with­out rub­ber over­lays. There­fore, it is rec­om­mend­ed to use gloves for com­fort in work.
  • Polypropy­lene pipe shears are dis­tin­guished by high-qual­i­ty assem­bly and a well-thought-out device. The toolk­it is suit­able for work­ing with pipes with a diam­e­ter of 5–40 mm. The blade char­ac­ter­izes strength, good sharp­en­ing angle. The han­dle has a com­fort­able lock that pre­vents the device from slip­ping out of the hands, as well as rub­ber inserts.
  • I‑TECH. It is a tele­scop­ic scis­sors for pipes made of polypropy­lene with a diam­e­ter of 60 mm. The prod­uct is pro­duced by a devel­op­er from Chi­na, in addi­tion to them, mod­els for thin plas­tic pipe rolling are avail­able for pur­chase. A tool of a bud­get cat­e­go­ry, has good tech­ni­cal para­me­ters, a thin steel blade.
  • Scis­sors for cut­ting pipes made of polypropy­lene from a devel­op­er from Ger­many, but the pro­duc­tion is made at fac­to­ries in Chi­na. Suit­able for 42mm tubes.

  • Mil­wau­kee Elec­tric Tool. Scis­sors for pipes made of polypropy­lene from a man­u­fac­tur­er in the USA. Cuts pipes in diam­e­ter from 12 mm to 63 mm. Charg­ing takes place from a 12 V bat­tery. The device has pos­i­tive reviews.
Pop­u­lar Mod­els

Today, there are a large num­ber of mod­els of scis­sors for plas­tic pipes on the build­ing mate­ri­als mar­ket, so the ques­tion of how to cut them will not arise. The user can com­pare mod­els and pur­chase the desired mod­i­fi­ca­tion in terms of para­me­ters and price. But, when a pipe cut­ter from a well-known man­u­fac­tur­er is select­ed, you need to make sure that the pur­chased prod­ucts are not fake.

Nuances in the work

To know how to use scis­sors, you need to read the step-by-step guide. Instruc­tions for cut­ting pipe with such scis­sors involves the fol­low­ing steps:

  • The mark­er marks the cut line on the prod­uct.
  • Placed on the markup blade-base.
  • Accu­ra­cy is con­trolled through a spe­cial slot.
  • Apply­ing a slight effort, the han­dles of the device are com­pressed.

The same scheme for cut­ting with guil­lo­tine shears. The dif­fer­ence lies in the fact that in this sit­u­a­tion the han­dles of the device are com­pressed 3–4 times to achieve the final cut.

The design fea­tures of guil­lotines have a mech­a­nism for return­ing the knife to its orig­i­nal posi­tion. There­fore, before the start of appli­ca­tion, by press­ing the return key, the cut­ter is set to its pre­vi­ous posi­tion. Usu­al­ly main­te­nance is required after 400–500 cuts.

Impor­tant! Using pro­file shears for cut­ting HDPE pipes in your work, you need to study the instruc­tions for use and act in accor­dance with the instruc­tions of the devel­op­er. Main­te­nance involves actions that are aimed at clean­ing and lubri­cat­ing each work­ing part of the device.

The case of the device is care­ful­ly opened, clean­ing is car­ried out and the parts are lubri­cat­ed with machine oil. In accor­dance with the oper­at­ing instruc­tions for the device, scis­sors for cut­ting poly­mer pipes are stored in the same pack­age in which they were pur­chased. It is for­bid­den to use a pipe cut­ting device that is made from a mate­r­i­al oth­er than poly­mers.

Fea­tures of the work

When it is nec­es­sary to replace a blade on a guil­lo­tine, prop­er dis­man­tling, sharp­en­ing or replace­ment is required. The pro­ce­dure for remov­ing the knife is as fol­lows:

  • The blade is installed in a posi­tion in which the heads of the fix­ing screws are vis­i­ble in the holes.
  • Use a Phillips screw­driv­er to loosen these screws.
  • The knife is removed from the body.

Now you need to sharp­en the dull part or mount a new blade in the oppo­site direc­tion.

How to cut polypropylene pipes without scissors

In order to cut plas­tic pipes, var­i­ous impro­vised means can be used. How­ev­er, it should be remem­bered that such a cut will not con­tribute to the high qual­i­ty of the future pipe. There­fore, it is nec­es­sary to con­sid­er the tools (in addi­tion to scis­sors), which will make it pos­si­ble to care­ful­ly cut the plas­tic pipeline:

  • hack­saw;
  • sharp­en­ing knife (with small teeth);

Cut­ting polypropy­lene pipes with a hack­saw or knife should not be tak­en as the main option. Their use can lead to the fact that the end of the pipe roll is frayed, burrs will form, which will need to be removed with emery or cleaned with a knife.

Scis­sors for work­ing with polypropy­lene pipes are use­ful and pop­u­lar tools that are designed to great­ly facil­i­tate work in the field of plumb­ing. Due to the large num­ber of struc­tures and prod­ucts, it became pos­si­ble to process rolled pipes of var­i­ous diam­e­ters with any wall thick­ness. These devices eas­i­ly cut not only ordi­nary pipes, but also met­al-plas­tic prod­ucts.
