HDPE Pipe Welding Machine Equipment Has Strong Thermal Storage Capacity And Timely Replenishment Capacity

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.

Tá am teocht leanúnach Shan fada. Is é fad an teocht leanúnach ná ceann de na siombailí tábhachtacha a bhaineann le feidhmíocht trealaimh táthú teite. Tá fadhb tomhais teasa fós ag an trealamh teite teite tar éis dó teocht a shocrú, go háirithe sa gheimhreadh, go bhfuil an tuyere, fiú sa bhearna neamhoibríochta, ró-mhór freisin, agus nuair a bhíonn an oibríocht, a phíopaí agus a feistis ídíonn fuinneamh teasa ar leithligh, a éilíonn go bhfuil cumas láidir stórála teirmeach ag an trealamh agus acmhainn athsholáthair tráthúil.

Second, must choose the qualified and suitable welding sleeve.

Tá an sleamhnán táthúcháin cáilithe deartha chun machnamh iomlán a dhéanamh ar an struchtúr trasdula agus doimhneacht weld an phíopa tar éis táthú, chomh maith le slaodacht an dromchla agus réidh le dromchla. I láthair na huaire, tá na céadta de tháirgeadh táirgthe baile de mhodhanna táthú teite le haghaidh línte pp-R, PPC, PE agus píopaí uisce eile. Mar gheall ar na déantóirí táirgeadh amhábhar, breiseáin, coinníollacha éagsúla comhshaoil, roghnú trealamh, ionas go mbeidh an méid píopa agus píopaí éagsúil. Dá bhrí sin, ní mór do na déantóirí agus na n-úsáideoirí píopa a gcuid sleamhnáin thrastúis píopa féin a roghnú. Maidir leis an oibreoir, ba cheart go gceanglófaí tar éis an táthú seo caite dromchla an sleamhnáin táthú a ghlanadh chun neamhíonachtaí a sheachaint sa chuid táthú.

For the pipe with more than 40mm caliber, because of the large caliber and the ability of non personal power, it is necessary to use mechanical equipment to ensure the depth and straightness of pipe entering the pipe. We found that in many construction sites with five to six workers on a 110mm interface for welding, fee Dickens can not guarantee the pipe straightness and insertion depth, the entire pipeline winding, it is difficult to imagine in a certain temperature and pressure conditions.

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

Ba chóir a rá nach fadhb í go dian i gcomhréir leis an bpróiseas táthú agus le riachtanais theicneolaíochta táthú oibriú tógála an chórais phíblíne, faoi ghnáth-theocht agus brú a úsáid. Mar sin féin, is minic a aimsímid i dtógáil píopaí agus feistis in acomhal feiniméan nó gaineamh pléasctha ó lá go lá.

The main reasons are as follows:

Shan Hot Melt welder temperature is not correct, too high or too low, the performance of polypropylene is changed;

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. Nós imeachta oibríochta táthú ceart.

Ullmhú táthú te-leá Shan

Shan don phíopa trastomhas seachtrach 25-110mm chun an béal beveling a chamfer go 15 chamfer leis an tiús balla tube de leath;

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

Shan when a pre assembled part is fused, the connection is marked in the position required by the pipe and the fitting.

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

Tar éis gach díscaoilte, ba chóir do Shan éadach tirim nó páipéar tirim a úsáid chun an teas agus an teas a théamh, ná glantach a úsáid.

Shan Hot Melt and connection

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.
