Installation of pipeline from steel pipes

[ad_1]

When installing any pipeline, it is impor­tant to prop­er­ly fix it. The reli­a­bil­i­ty of any future sys­tem direct­ly depends on the qual­i­ty of this oper­a­tion. When attach­ing steel pipes to a wall, you need to fol­low the rules for per­form­ing this work, choose high-qual­i­ty fas­ten­ers, and pre­lim­i­nar­i­ly cal­cu­late the design scheme. This will cre­ate a reli­able com­mu­ni­ca­tion sys­tem that will last a long time.

Types of fasteners

Steel pipes are attached to the wall using sev­er­al types of fas­ten­ers:

  • Spe­cial sta­ples.
  • Arms.
  • Clamps of the required con­fig­u­ra­tion.

All ele­ments must be select­ed tak­ing into account the out­er diam­e­ter of the sys­tem to be installed, the require­ments for the appear­ance of the line, and pos­si­bly the fre­quen­cy of mount­ing and dis­man­tling con­nec­tions, join­ing flanges and the entire struc­ture.

With­out reli­able fas­ten­ings, it is impos­si­ble to lay a pipeline. First you need to choose an ele­ment suit­able for your con­di­tions, and cor­rect­ly assem­ble the sys­tem.

metal clamps

The design is the same for large and small­est clamps, the kit includes:

half rings Allows you to secure­ly clamp the pipe. Two half-rings are con­nect­ed togeth­er with bolts, they allow you to adjust the com­pres­sion force.
Rub­ber gas­kets They are put on half rings, they serve to clamp the pipe tight­ly, reduce the vibra­tion that occurs when pump­ing liq­uid.
Stud fas­ten­ing It is weld­ed to the half ring, it has threads with a diam­e­ter of 8–10 mm, it is used for the instal­la­tion of pipelines. The length can be dif­fer­ent 80–180 mm. When pur­chas­ing clamps, you need to cal­cu­late the required length of this ele­ment, tak­ing into account the design of the pipeline.

The advan­tage of these prod­ucts is their long ser­vice life and reli­a­bil­i­ty, the dis­ad­van­tage is that it is incon­ve­nient to hide from the eyes indoors.

Clips

Many peo­ple know such ele­ments, with their help they install main­ly thin pipelines, they dif­fer in that:

  • Poly­styrene is used in the pro­duc­tion — a reli­able and durable mate­r­i­al that serves for a long time, suc­cess­ful­ly resists exter­nal influ­ences.
  • Prod­ucts can be sin­gle and dou­ble, the design speeds up the lay­ing of the sys­tem.
  • It is pos­si­ble to assem­ble the required struc­ture from sev­er­al ele­ments for lay­ing dif­fer­ent branch­es (for exam­ple, pipelines with cold and hot water) thanks to the grooves on the prod­ucts.
  • Spe­cial clips are able to hold pipes with a diam­e­ter of 15–50 mm.
  • They are installed using self-tap­ping screws or dow­els, which sim­pli­fies instal­la­tion.

Pipe clamps

Sim­i­lar to clips, these prod­ucts have their own char­ac­ter­is­tics:

  • The main dif­fer­ence is the closed fas­ten­er, with its help you fix the pipe, and not just snap it. This increas­es reli­a­bil­i­ty, which is impor­tant on ver­ti­cal sys­tems.
  • They pro­duce 2 types of prod­ucts, in the first, a self-tap­ping screw holds the clamp hold­ing the pipeline and fix­es the mount in the wall. In the sec­ond ver­sion, the snap-on part is sep­a­rat­ed from the self-tap­ping screw and, for dis­man­tling the installed steel pipes, it is not nec­es­sary to unscrew the screws.
  • There are prod­ucts in which dow­els are bought sep­a­rate­ly, they attract with their cheap­ness.

They make it pos­si­ble to secure­ly fix the laid pipeline.

Staples

Man­u­fac­tured from gal­va­nized steel for dura­bil­i­ty. They are used in places where dura­bil­i­ty and reli­a­bil­i­ty are impor­tant. Pay atten­tion to the thick­ness of the brack­et, thick met­al can with­stand heavy loads:

  • The clas­sic design is a curved brack­et with two legs, on both sides of which there are lugs for instal­la­tion in place. The most impor­tant thing is to choose the appro­pri­ate diam­e­ter of the prod­ucts.
Steel brace
  • The sec­ond option is a brack­et in the form of a P‑shaped prod­uct, in which 2 strips are con­nect­ed togeth­er and have one hole for installing prod­ucts. They are well suit­ed for mount­ed water pipes, cor­ru­ga­tions and so on. They can clamp pipes with a diam­e­ter of 10–120 mm.
  • Sta­ples with one foot are used for light loads.

Prod­ucts can be used togeth­er with a rub­ber gas­ket to secure­ly fix and reduce pos­si­ble vibra­tions.

Choice of pipe fastening

The eas­i­est and cheap­est way is to fix the pipes with non-sep­a­ra­ble brack­ets. Clamps with a rub­ber gas­ket installed in them will cost a lit­tle more, but they are con­ve­nient to install and in the future you can dis­man­tle the required part of the pipeline, for exam­ple, to replace steel pipes, and then reassem­ble the sys­tem. Brack­ets are used infre­quent­ly, main­ly when installing com­plex pipelines.

When lay­ing steel struc­tures, do not for­get that when they are filled with water, they weigh a lot. There­fore, you need to choose devices that can with­stand the total mass of the high­way. It is impor­tant to choose the right ele­ment that rigid­ly con­nects it to the wall, it can be an anchor or a dow­el. You need to take into account the total weight of the sys­tem and the flu­id mov­ing through it, and then divide this mass by the num­ber of attach­ment points. As a result, you will get the weight act­ing on one anchor (dow­el).

Clamps of var­i­ous sizes

It is nec­es­sary to take into account the load-bear­ing qual­i­ties of the wall mate­r­i­al. When installing a pipeline made of steel pipes on con­crete walls, there will be no prob­lems with reli­a­bil­i­ty. When fas­ten­ing the struc­ture to walls made of wood, gas block and sim­i­lar mate­ri­als, with a low shear or tear force, you will have to buy more pow­er­ful fas­ten­ers. On such mate­r­i­al, it is desir­able to make more attach­ment points for the sys­tem for reli­able fas­ten­ing.

Steel Pipe Installation Tips

The instal­la­tion of the pipeline is car­ried out by fol­low­ing sev­er­al manda­to­ry rules:

  • The ver­ti­cal instal­la­tion of the lay­ing line is per­formed using more fas­ten­ers, com­pared with the instal­la­tion in a hor­i­zon­tal posi­tion.
Pipeline instal­la­tion
  • When installing steel pipes of small thick­ness, more fix­a­tion points must be made than when installing large prod­ucts.
  • On the bend at the bot­tom of the ver­ti­cal­ly fixed pipe, in the area where it goes into the hor­i­zon­tal, you need to fix an addi­tion­al clamp. It is unac­cept­able that the deform­ing load from the ver­ti­cal branch of the sys­tem is direct­ly trans­ferred to the “bed”.
  • When installing a ris­er not exceed­ing 3m, fas­ten­ings can be omit­ted. If the sys­tem turns out to be longer than 3 m, then a mount must be installed in the cen­ter of the floor.
  • Pipes lead­ing to heat­ing appli­ances must be car­ried out by installing fas­ten­ers every 1.5 m.

A sim­ple table will allow you to choose the appro­pri­ate pitch between indi­vid­ual fas­ten­ers on hor­i­zon­tal sec­tions:

Cross sec­tion mm

Max­i­mum dis­tance between sup­ports of steel pipelines in meters
Non-iso­lat­ed

Iso­lat­ed

fif­teen 2.5 1.5
twen­ty 3 2
25 3.5 2
32 four 2.5
40 4.5 3
fifty 5 3
70.8 6 four
100 6 4.5
125 7 5
150 eight 6

*

These data will allow you to deter­mine the required dis­tance between the indi­vid­ual fas­ten­ers for pipes of dif­fer­ent diam­e­ters.

Any sys­tems must be mount­ed tak­ing into account the tem­per­a­ture regime. When the air is heat­ed or at a high tem­per­a­ture of the coolant, the met­al inevitably expands, this can­not be com­plete­ly elim­i­nat­ed by lay­ing rein­forced pipes. Assem­bly of the heat­ing sys­tem is best done using a slid­ing joint or plas­tic brack­ets.

Required space between support points according to SNIP

A suit­able dis­tance between the pipeline sup­port points is an impor­tant char­ac­ter­is­tic for the oper­a­tion of the sys­tem. The points where the fas­ten­ers are installed make it pos­si­ble to even­ly dis­trib­ute the exist­ing load, to min­i­mize pos­si­ble stress. When lay­ing heat­ing mains, suc­cess­ful­ly dis­trib­ute the tem­per­a­ture load.

The char­ac­ter­is­tics giv­en in the SNiP tables con­tain the require­ments for the allow­able free space between the fixed sup­ports, tak­ing into account the pur­pose of the sys­tem. These data must be in the tables, which great­ly sim­pli­fy the cal­cu­la­tion of the sys­tem. Do not for­get that the table does not con­tain rec­om­mend­ed data, but the spe­cif­ic dis­tance cor­re­spond­ing to SNiP, at what dis­tance, what fas­ten­ers and how many should be installed.

SNIP data

The choice of suit­able hold­ers direct­ly depends on the fea­tures of the sys­tem being mount­ed and the lev­el of future load on the ele­ments used. The free loca­tion of the pipeline is required where the effect of expan­sion under the influ­ence of high tem­per­a­ture is pos­si­ble. Suit­able fas­ten­ers allow the expand­ing ele­ments to move freely when heat­ed, but hold the sys­tem well on the wall sur­face.
