Features of installation of heating and plumbing systems with copper pipes

[ad_1]

Pro­vid­ing the premis­es with heat and water is a pre­req­ui­site for a com­fort­able stay for the fam­i­ly. There­fore, the instal­la­tion of heat­ing and water sup­ply with cop­per pipes is one of the options for form­ing a sys­tem designed for long-term oper­a­tion due to the struc­ture of the mate­r­i­al. In addi­tion, such prod­ucts are sim­ply mount­ed and con­nect­ed.

Design fea­tures

The assem­bly of cop­per prod­ucts for cold and hot branch­es has prac­ti­cal­ly no tech­no­log­i­cal dif­fer­ences; the main thing is to take into account the type of con­nec­tion and the cat­e­go­ry of the pipe itself.

Impor­tant! Hot water fit­tings are cov­ered with a spe­cial heat-insu­lat­ing mate­r­i­al made of PVC film.

The instal­la­tion of the water sup­ply itself is car­ried out in one of 2 options:

With fit­ting

*

For do-it-your­self instal­la­tion of cop­per water pipes, the most afford­able option is col­let con­nec­tions using thread­ed fit­tings, adapt­ed for repeat­ed use if dis­as­sem­bly or assem­bly is nec­es­sary.

To use them in the instal­la­tion you need:

  • put a com­pres­sion fit­ting on the cop­per tube;
  • fix the crimp ring on top;
  • con­nect all applied parts and tight­en the nut.

Impor­tant! The fer­rule is intend­ed for sin­gle use in order to give the struc­ture tight­ness, so if the sys­tem has to be dis­as­sem­bled, a new ele­ment should be pre­pared in advance.

The num­ber of fit­tings used is saved due to the flex­i­bil­i­ty of pipes for the heat­ing heat­ing sys­tem in the house.

When using the sol­der­ing method on your own, you need to stock up on knowl­edge and it’s good to have expe­ri­ence in using sol­der­ing equip­ment.

The whole process con­sists of the fol­low­ing steps:

  • clean­ing the edges of pipes and fit­tings to final clean­li­ness;
  • using a brush, you need to cre­ate a thin lay­er of sol­der­ing flux;
  • insert the pipe into the fit­ting to the max­i­mum;
  • the fold­ed con­nect­ing unit is even­ly heat­ed by a gas burn­er or a build­ing hair dry­er, so that heat­ing occurs equal­ly over the entire area, it is bet­ter to use a blow­torch with 2 burn­ers;
  • when the heat­ing tem­per­a­ture reach­es the set val­ue for melt­ing the sol­der, it is intro­duced into the junc­tion;
  • after hard­en­ing, excess flux is removed.

To deter­mine the exact heat­ing of the joint, it is nec­es­sary to touch it with sol­der, if it melts, then the mate­r­i­al is ready for fur­ther action.

Impor­tant! In order not to guess the moment of intro­duc­ing sol­der, it is bet­ter to mount cop­per pipes pro­vid­ed for sale with pre­pared mate­r­i­al in a spe­cial chute. As soon as the con­nec­tion is heat­ed to the required tem­per­a­ture, the sol­der will fill the gap between the pipe and the fit­ting, con­nect­ing them secure­ly.

Material preparation

*

How­ev­er, the process of installing cop­per pipes is pre­ced­ed by a moment of prepa­ra­tion — the mate­r­i­al is eas­i­ly cut and bent, but every­thing should be done cor­rect­ly. In addi­tion, con­sid­er the clas­si­fi­ca­tion of cop­per prod­ucts.

More­over, each prod­uct has its own mark­ing, which great­ly sim­pli­fies the selec­tion of mate­r­i­al.

Tips

Selec­tion rules

In order to choose the right pipe for instal­la­tion, the fol­low­ing nuances should be tak­en into account dur­ing the acqui­si­tion process:

  • den­si­ty — it is bet­ter to give pref­er­ence to a mate­r­i­al with a low den­si­ty, then the acqui­si­tion will occur prod­ucts with a small weight;
  • low coef­fi­cient of ther­mal con­duc­tiv­i­ty — pro­vides an oppor­tu­ni­ty to deter­mine how quick­ly heat loss occurs;
  • melt­ing point of the mate­r­i­al — the study of this item makes it pos­si­ble to reg­u­late the tem­per­a­ture of the water in it after assem­bly;
  • out­er sur­face — must be smooth with­out pores so as not to trap dirt par­ti­cles;
  • expan­sion of the web under heat­ing will pro­vide an oppor­tu­ni­ty to under­stand how much expan­sion will occur at high tem­per­a­ture con­di­tions.

Types of fittings

Fit­ting options

*

For fas­ten­ing, 2 types are used:

  • cap­il­lary — for weld­ing through the use of sol­der, which is attract­ed on a cap­il­lary basis and fills voids;
  • press fit­ting — an option for mount­ing cop­per pipelines using crimp­ing and relat­ed acces­sories. This option is con­ve­nient, fast and safe, but the com­po­nents are high­er.

Installation option taking into account the method of water supply

The pecu­liar­i­ty of installing cop­per pipes depends on the method of water sup­ply and can be done in 2 options:

  • sin­gle-pipe — sim­ple, since the radi­a­tors are mount­ed in series one after the oth­er accord­ing to the prin­ci­ple of a ring in which water cir­cu­lates;
  • two-pipe — radi­a­tors are installed in par­al­lel and equipped with addi­tion­al heat exchang­ers that pro­vide water tem­per­a­ture con­trol.

Impor­tant! Before start­ing the heat­ing sys­tem, it is nec­es­sary to ini­tial­ly check the assem­bled struc­ture through the action of excess pres­sure.

Mounting tools

Tools

In order to stock up on the exact amount of mate­ri­als before instal­la­tion, it is nec­es­sary to draw up a dia­gram in which to mark the place­ment of the sys­tem, and cal­cu­late the amount of mate­r­i­al and addi­tion­al com­po­nents.

To mount pipes, you should pre­pare spe­cial devices:

  • Pipe cut­ter or hack­saw.
  • Man­u­al cal­i­bra­tor.
  • Span­ners.
  • File.
  • Sol­der­ing torch.

Dur­ing the instal­la­tion process, process­es such as cut­ting, bend­ing, assem­bling units, sol­der­ing, press­ing and weld­ing will be per­formed. In addi­tion, end siz­ing and debur­ring, debur­ring, flux appli­ca­tion and debur­ring.

The heat­ing sys­tem must be pro­tect­ed from heat loss, includ­ing radi­a­tors. The most opti­mal mate­r­i­al for this is poly­eth­yl­ene foam. A pro­tec­tion has been cre­at­ed as a shell for the pipe. It costs a pen­ny, but the heat sav­ings are sig­nif­i­cant.

The whole instal­la­tion fea­ture is as fol­lows:

  • cut the can­vas­es into seg­ments accord­ing to mea­sure­ments, using a hack­saw or pipe cut­ter for this;
  • clean­ing from burrs and oth­er flaws;
  • the place of the cut is also addi­tion­al­ly aligned;
  • if nec­es­sary, bend the prod­ucts man­u­al­ly or using a spe­cial mate­r­i­al;
  • if there are spe­cial curved sec­tions, a pipe ben­der should be used;
  • it is impor­tant to take into account the max­i­mum per­mis­si­ble radius;
  • the bend­ing radius dur­ing man­u­al oper­a­tion should not decrease below 8 diam­e­ters, and when using a tool, not less than 3.5 pipeline diam­e­ters.

Impor­tant! Cop­per pipes should not be con­nect­ed to alu­minum radi­a­tors.

If they are used, a steel pipe should be used as an adapter to avoid the for­ma­tion of cor­ro­sion.

Pros and cons of copper piping

Cop­per pipeline

All the fea­tures of oper­a­tion from cop­per pipes of the heat­ing sys­tem are in the numer­ous advan­tages of the mate­r­i­al:

  • harm­less with bac­te­ri­ci­dal prop­er­ties;
  • dura­bil­i­ty of appli­ca­tion with the preser­va­tion of oper­a­tional qual­i­ties;
  • resis­tance to cor­ro­sion and ultra­vi­o­let;
  • work in a wide tem­per­a­ture range from ‑200 to +350 degrees;
  • do not react with chlo­rine in water;
  • have high ther­mal con­duc­tiv­i­ty, which affects the effi­cien­cy;
  • lack of plaque for­ma­tion;
  • resis­tant to freez­ing, with­stand the process up to 4 times;
  • with­stand pres­sure up to 200 — 400 atmos­pheres;
  • vibra­tion resis­tant;
  • pre­sent­ed in a wide range;
  • are 100% recy­cled.

How­ev­er, a sig­nif­i­cant dis­ad­van­tage of such a pipeline is:

  • high price of pipes and com­po­nents — since cop­per itself has a high price and its pres­ence in the com­po­si­tion of the prod­uct leads to its high cost;
  • high den­si­ty of the mate­r­i­al com­pared to steel, which makes the entire sys­tem heav­ier;
  • the com­plex­i­ty of the instal­la­tion option by sol­der­ing, it requires the pres­ence of a pro­fes­sion­al mas­ter.

But this is noth­ing com­pared to the dura­bil­i­ty of prod­ucts.

Conclusion

The cop­per pipe heat­ing sys­tem has many advan­tages, so it is in demand. Its main advan­tage is high heat trans­fer and dura­bil­i­ty of oper­a­tion. Cop­per pipes look aes­thet­i­cal­ly pleas­ing with­out heat-insu­lat­ing mate­r­i­al. But the cost of such sys­tems is high, giv­en that a spe­cial­ist must par­tic­i­pate in their assem­bly.
