Overview of polypropylene pipes

[ad_1]

The build­ing mate­ri­als mar­ket is con­stant­ly expand­ing, as new inno­v­a­tive pro­duc­tion tech­nolo­gies appear. Recent­ly, poly­mer­ic mate­ri­als have been wide­ly demand­ed, which are divid­ed into sev­er­al types. For the most part, these are polypropy­lene prod­ucts from domes­tic and for­eign man­u­fac­tur­ers. Many con­sumers are inter­est­ed in which fit­tings are bet­ter and for what pur­pos­es, so in the arti­cle we will con­sid­er the rat­ing of pro­duced polypropy­lene pipes.

1) Rein­forced look.

Polypropylene pipe products: characteristics

To choose the right prod­uct cor­rect­ly, you need to under­stand what advan­tages polypropy­lene prod­ucts have:

  • They are not afraid of destruc­tive cor­ro­sion process­es. Thanks to this prop­er­ty, pipelines retain their orig­i­nal prop­er­ties for many years. Com­pared to met­al prod­ucts, fit­tings made of polypropy­lene last 3–4 times longer;
  • Chem­i­cal­ly active media do not affect the mate­r­i­al. In addi­tion, polypropy­lene pipes are good due to their excel­lent through­put;
  • Frost resis­tance. Such prod­ucts can also be oper­at­ed at sub-zero tem­per­a­tures — they will reli­ably per­form their duties with­out being sub­ject­ed to breaks;
  • Small noise lev­el. Often, when arrang­ing heat­ing sys­tems, con­sumers choose polypropy­lene prod­ucts, because the sounds of water move­ment through them are sim­ply not audi­ble;
  • In the case of a hot coolant, ther­mal ener­gy is saved by 10 — 20% com­pared to met­al prod­ucts;
  • Envi­ron­men­tal­ly friend­ly prod­ucts, harm­less to both humans and the envi­ron­ment;
  • Eas­i­ly mount­ed and cre­ate a reli­able con­nec­tion;
  • Con­nect­ing ele­ments (fit­tings) are pre­sent­ed in a large assort­ment, which makes it pos­si­ble to imple­ment even com­plex wiring.

Polypropylene pipes: main types

Before choos­ing a prod­uct, you need to under­stand its types. Pipes made of polypropy­lene are sin­gle or mul­ti­lay­er.

Prod­ucts with one lay­er are:

  • PPH is homo­propy­lene. With the help of such prod­ucts, ven­ti­la­tion sys­tems, indus­tri­al pipelines are laid and cold water sup­ply is equipped;
  • PPB is polypropy­lene block copoly­mer. Using this type, floor heat­ing sys­tems and cold water mains are cre­at­ed, high-impact fit­tings are pro­duced;
  • PPR is a polypropy­lene rad­no­copoly­mer. Rel­e­vant for water sup­ply and heat­ing;
  • PPs is flame retar­dant spe­cial­ty polypropy­lene.
3) PP-RCT

As for mul­ti­lay­er prod­ucts, it involves rein­force­ment. Due to this, tem­per­a­ture elon­ga­tions are reduced, and the prod­ucts them­selves, in turn, are divid­ed into smooth and per­fo­rat­ed.

They dif­fer in the way of rein­force­ment into the fol­low­ing types:

  • With a sol­id or per­fo­rat­ed lay­er of alu­minum foil installed on the out­side;
  • Clos­er to the out­side there is an alu­minum lay­er, and a per­fo­rat­ed foil allows you to con­nect the lay­ers to each oth­er with­out the help of glue;
  • With the use of fiber­glass;
  • The inner lay­er is made of a com­pos­ite mix­ture con­sist­ing of polypropy­lene and glass or fiber.

The best polypropylene pipes for the heating system

Many con­sumers are won­der­ing, “which polypropy­lene pipes are bet­ter to install for heat­ing?”. Each man­u­fac­tur­er guar­an­tees that its prod­ucts are of high qual­i­ty and durable. There­fore, we com­pare the prod­ucts of dif­fer­ent com­pa­nies accord­ing to the fol­low­ing para­me­ters: main char­ac­ter­is­tics (diam­e­ters, weight), appear­ance, strength indi­ca­tors and ser­vice life.

Faser

Czech man­u­fac­tur­er, whose prod­ucts are divid­ed into 2 types:

  • FV PPR — such prod­ucts are suit­able for cold and hot water sup­ply. Opti­mal for pro­longed con­tact with water at room tem­per­a­ture, while main­tain­ing peri­od­ic con­tact with hot water. Method of their man­u­fac­ture: weld­ing. Fas­er is addi­tion­al­ly engaged in the pro­duc­tion of all nec­es­sary com­po­nents for pipes: these are fit­tings, acces­sories and oth­er items;
  • FV THERM — opti­mal for heat­ing sys­tems, con­nect­ed to radi­a­tors and under­floor heat­ing sys­tems. With their help, you can orga­nize the sup­ply of hot water, but the solu­tion is not appro­pri­ate due to the high cost of pro­duc­tion. The fol­low­ing mate­ri­als are used in the man­u­fac­tur­ing process: polypropy­lene, rigid polyurethane and expand­ed poly­styrene — this com­bi­na­tion pro­vides a long ser­vice life and a low stretch fac­tor.

A run­ning meter of prod­ucts from Fas­er weighs an aver­age of 0.1 kg.

4) Fas­er with fiber­glass rein­force­ment.

East

Calde-Vos­tok is a man­u­fac­tur­er that has become wide­ly pop­u­lar in Europe and Europe. A com­pa­ny from Turkey is engaged in the man­u­fac­ture of taps for cold and hot water sup­ply, fit­tings, taps and oth­er nec­es­sary acces­sories. The com­pa­ny uses recy­cled polypropy­lene to man­u­fac­ture its prod­ucts and com­bines it with oth­er syn­thet­ic mate­ri­als to increase dura­bil­i­ty.

For the man­u­fac­ture of branch pipes, a mul­ti­lay­er mate­r­i­al is used, which makes the con­nec­tion more durable and reli­able. The pipes them­selves are pro­duced in white and are marked. As for diam­e­ters, the man­u­fac­tur­er offers all com­mon sizes. If nec­es­sary, you can order the orig­i­nal prod­uct.

Wefatherm

The com­pa­ny man­u­fac­tures polypropy­lene prod­ucts for heat­ing sys­tems and water sup­ply. The range of the brand con­sists of tubu­lar prod­ucts, includ­ing those rein­forced with alu­minum, var­i­ous fit­tings and acces­sories. Prod­ucts are char­ac­ter­ized by the fol­low­ing pos­i­tive qual­i­ties:

  • Due to the smooth inner sur­face of the pipes, low pres­sure loss­es are ensured;
  • A large selec­tion of addi­tion­al fit­tings allows you to com­bine Wefa­therm pipelines with oth­er sys­tems.

They are con­nect­ed by dif­fu­sion weld­ing, which ensures max­i­mum tight­ness. This type of con­nec­tion is quick­ly processed and cools down.

5) Prod­ucts for heat­ing sys­tems.

Banninger

A Ger­man com­pa­ny pro­duc­ing high qual­i­ty prod­ucts. Each stage of pro­duc­tion is strict­ly con­trolled, and the raw mate­ri­als used in the work are of impec­ca­ble qual­i­ty. Such pipes are used in a wide vari­ety of areas, start­ing with under­floor heat­ing sys­tems, heat sup­ply, drink­ing water sup­ply and end­ing with pro­duc­tion.

Con­sid­er the fea­tures of fit­tings of the PN20 and PN16 series. They are used for hot and cold water sup­ply. For the man­u­fac­ture of prod­ucts, PP-RCT polypropy­lene is used — an inno­v­a­tive mate­r­i­al with a crys­talline struc­ture, the per­for­mance of which is 50% bet­ter com­pared to ana­logues. The pecu­liar­i­ty lies in the fact that a spe­cial cool­ing method is involved, which is the rea­son for the for­ma­tion of the small­est crys­tals. The result is the most dense and, at the same time, flex­i­ble mate­r­i­al. This allows the mate­r­i­al to show high resis­tance to pres­sure — up to 20 bar and tem­per­a­ture — up to +95 degrees Cel­sius.

Anoth­er series — Stabi, is a mul­ti­lay­er prod­uct made of com­pos­ite mate­ri­als. Rel­e­vant for heat­ing sys­tems, hot and cold water sup­ply. The pecu­liar­i­ty of the prod­uct lies in the coat­ing with an alu­minum lay­er, due to which it is char­ac­ter­ized by low ther­mal expan­sion and excel­lent mechan­i­cal resis­tance. To con­nect them, ther­mal weld­ing is used using a man­u­al weld­ing machine.

Pro Aqua

The com­pa­ny “Ego Engi­neer­ing” offers a choice of the fol­low­ing series of fit­tings:

  • PP‑R — a ran­dom copoly­mer is used for their pro­duc­tion. Such taps can last about 50 years. Sizes: 20 — 125 mm;
  • PEX is a sys­tem with an anti-dif­fu­sion coat­ing. With their help, hot and cold water sup­ply sys­tems are assem­bled. Have the advan­tages of two mate­ri­als: met­al and polypropy­lene;
  • PE-RT — their fea­ture is increased heat resis­tance. With their help, radi­a­tors, boil­ers and oth­er heat­ing equip­ment are con­nect­ed.

Accord­ing to exter­nal signs, the fit­tings prac­ti­cal­ly do not dif­fer, except for the col­or of the mark­ing.

Polypropylene pipes for water supply: manufacturer rating

First, let’s take a look at what such a prod­uct is in gen­er­al. These are the most suit­able prod­ucts if the goal is to cre­ate a reli­able water sup­ply in the house. Choos­ing and com­par­ing tech­ni­cal char­ac­ter­is­tics, it turns out that polypropy­lene is sev­er­al times supe­ri­or to mate­ri­als such as poly­eth­yl­ene and polyvinyl chlo­ride. This type of plas­tic is char­ac­ter­ized by the low­est den­si­ty index — 0.91 g/cm3.

Depend­ing on the prod­uct class, polypropy­lene fit­tings can be used to orga­nize both hot and cold water sup­ply. High-qual­i­ty polypropy­lene fit­tings and pipes may dif­fer from each oth­er, there­fore, when choos­ing, you should pay atten­tion to the mark­ing, which indi­cates the man­u­fac­tur­ing tech­nol­o­gy and char­ac­ter­is­tics.

PPH and PPR prod­ucts are con­sid­ered the most opti­mal for orga­niz­ing water sup­ply. As for the for­mer, they have a large mar­gin of safe­ty, but react poor­ly to low tem­per­a­tures (below 0) and expo­sure to ultra­vi­o­let radi­a­tion. Based on GOSTs and SNiPs, pro­fes­sion­als rec­om­mend using them to lay lines for cold water.

6) High­way made of plas­tic pipes.

The best heat resis­tance (can with­stand up to +900 degrees Cel­sius) and resis­tance to UV rays for PPR prod­ucts. Such pipes are suit­able for the orga­ni­za­tion of cold, hot water sup­ply and for heat­ing sys­tems. There is only one caveat — they should be mount­ed in heat­ed rooms, and they are not rec­om­mend­ed for out­door con­di­tions. We are talk­ing about sin­gle-lay­er fit­tings, while rein­forced two-lay­er ones are more suit­able for heat­ing.

When choos­ing pipes, you should pay atten­tion to the mark­ing:

  • PN10 — thin-walled prod­ucts for cold water sup­ply and under­floor heat­ing sys­tems, with a work­ing flu­id tem­per­a­ture of not more than +450 degrees Cel­sius;
  • PN16 — a uni­ver­sal option for cold water and hot water, with a tem­per­a­ture not exceed­ing +600 degrees;
  • PN20 — thick-walled rein­force­ment that can with­stand tem­per­a­tures of +950 degrees;
  • PN25 — sug­gest rein­force­ment, suit­able for hot water and heat­ing sys­tems.

Now as for the best options for polypropy­lene pipes. It should be not­ed here that the pro­duc­tion tech­nol­o­gy is the same in all cas­es, but each man­u­fac­tur­er adds cer­tain plas­ti­ciz­ers to the mate­r­i­al, aimed at improv­ing one or anoth­er char­ac­ter­is­tic.

The most pop­u­lar man­u­fac­tur­ers:

  • Rehau, Ban­ninger (Ger­many);
  • Ecoplas­tic FIBER (Nether­lands);
  • Val­tec (Italy);
  • TEBO, Ves­bo (Turkey);
  • ProAqua, Politek (Europe).

Man­u­fac­tur­ers offer prod­ucts of almost the same qual­i­ty. The only thing is that for a brand, for exam­ple, Rehau, you will have to pay extra, while Chi­nese options, on the con­trary, will cost less. Euro­pean prod­ucts also have their advan­tages, first of all, avail­abil­i­ty.

Conclusion

Polypropy­lene fit­tings are an excel­lent alter­na­tive com­pared to clas­sic met­al prod­ucts. Plas­tic pipes are not only afford­able, but also have opti­mal tech­ni­cal char­ac­ter­is­tics. Polypropy­lene lines can serve for about 50 years, but for this you need to choose the right pipes. For exam­ple, if you choose an unsuit­able prod­uct for hot water sup­ply, then the sys­tem will last at best 15 to 20 years. There­fore, when choos­ing a mate­r­i­al, you must be extreme­ly care­ful.
