HDPE hodiak soldatzeko makina ekipamenduak biltegiratze termikoko ahalmena eta berritzea puntuko gaitasuna ditu

How to weld HDPE Pipe Welding Machine to ensure the quality of PP-R tubing welding:

One, must choose the quality qualified hot melt welder.

Shan temperature control should be correct. PP-R Hot Melt Welding temperature is: 253. If the temperature is below 253 Shan, the pipes and fittings are only a thin surface of the melting, once they are fused between, the strength of the weld is not guaranteed, this is what we usually call false welding phenomenon; Conversely, if the temperature is above 274 Shan, the surface molecules of pipes and fittings are destroyed by high temperature, so that pp-r form thin liquid, after connecting will make the pipe diameter smaller, more importantly, the connection part will occur brittle crack, especially in the piping system completed after the water pressure, Such problems often occur.

Shan tenperatura tenperatura denbora luzea da. Tenperatura konstantearen luzera urtuko soldadura ekipoen errendimenduaren ikur garrantzitsuenetako bat da. Hot-melt ekipamenduak oraindik ere bero kontsumitzen duen arazoa du, tenperatura finkatzeko, batez ere neguan, batez ere neguan, nahiz eta ez funtzionamendu hutsean, bere beroaren kontsumoa oso handia da, eta operazioa behin bere hodiak eta burdinolak dira. Aparteko bero energia kontsumitzen dutenak, ekipamenduak eskatzen ditu biltegiratze termiko sendoa eta berreskuratzeko gaitasun egokia.

Second, must choose the qualified and suitable welding sleeve.

The qualified welding sleeve is designed to fully consider the transverse structure and weld depth of the pipe after welding, as well as the surface viscosity and surface smoothness. At present, the domestic production of hot melt welding method of pp-R, PPC, PE and other water pipes manufacturers have hundreds of. Because the manufacturers of the production of raw materials, additives, different environmental conditions, equipment selection, so that the production of pipe and pipe size is different. Therefore, the pipe manufacturers and users must choose their own pipe diameter welding sleeve. For the operator, after the last welding should be required to clean the surface of the welding sleeve to avoid impurities in the welding part.

40 mm-ko kaliburua baino gehiagoko kanalerako, kaliburu handia eta botere pertsonaleko gaitasuna dela eta, ekipamendu mekanikoa erabili behar da kanalizazioan dagoen kanalizazioaren sakontasuna eta zuzena ziurtatzeko. Aurkitu genituen bost sei sei langile soldatzeko 110mm interfaze batean eraikitako gune askotan Dickensek ezin duela hodi zuzentasuna eta txertatze-sakonera bermatu, hoditeria osoa, oso zaila da tenperatura eta presio baldintza jakin batzuetan imajinatzea.

Third, hot melt welding in the easy to occur problems.

Kontuan izan behar da soldadura prozesua eta soldadura teknologiaren baldintzak betetzeak hoditeriaren sistemaren funtzionamendurako, tenperatura normala eta erabiltzeko presioa ez dela arazoa. Hala ere, eguneroko eguneroko eraikuntzan hodien eta burdineriaren eraikuntza lehertu egin daiteke lehertu egin daitekeen fenomeno edo harea.

The main reasons are as follows:

Shan Hot Melt soldatzailea tenperatura ez da zuzena, oso altua edo oso baxua, polipropilenoa errendimendua aldatzen da;

Shan the surface of the welding sleeve is not properly disposed, or the surface coating falls off to make the contact part of the pipe produce sand hole;

The size of the Shan welding sleeve is not correct, so the melting depth and weld structure of the pipe are not suitable.

The welding surface of the pipe is not cleaned before the Shan welding.

Shan welded pipes and fittings do not maintain concentric or straight lines.

IV. Correct welding operation procedure.

Preparation of Shan hot-melt welding

Shan for the outer diameter 25-110mm pipe to chamfer the beveling mouth to 15 chamfer to the original tube wall thickness of half;

The Shan is cleaned with a cleaning machine (or alcohol) and a brush to the surface of the weld part of the pipe;

Aurrez muntatutako zatiak fusionatzen direnean, lotura hodiak eta egokitzea eskatzen duen kokapenean markatuta dago.

Sham 40mm caliber above the pipe welding must use the plane and the vertical pipe welding machine;

After each dissolution, Shan should use dry cloth or dry paper to clean the heating sleeve and heating head, do not use detergent.

Shan Hot Melt eta konexioa

Shan The tubes and fittings are inserted into the heating sleeve and the heating head, do not rotate or move too fast (to make the material melt time).

After the Shan is heated, remove the pipes and fittings from the heating element and do not rotate the heating part.

Shan the pipe and fittings are pressed along the axis immediately after heating, do not rotate. Strictly adhere to the hot-melt welding standards to maintain the time and cooling time.
