HDPE Water Pipe The most common connection methods are: hot melt connection, fused connection, socket-type flexible connection, flange connection, steel-plastic transition joint connection.

1, HDPE Water Pipe hot melt connection

Hot-melt connection is a special heating tool, under pressure in the HDPE Water Pipe or pipe fittings to be connected to the part to be melted, remove the heating tool, the pressure of the two melting surface together, at a steady pressure for a period of time , Until the joint cools. Hot melt connections include hot melt butt connection, hot melt socket connection, hot melt saddle connection.

Tá sreang friotaíochta tógtha i gceangal comhleádaithe le cuid de bhusca speisialta den nasc leis an bpíopa i ndlúth-theagmháil leis an gcumhacht, trí na páirteanna nasc teasa sreinge frithsheasmhachta leabaithe, ionas go mbeidh an comhtháthú, go dtí an comhfhuaraithe. Is féidir an nasc comhleádaithe a úsáid chun ceangal le feistis Píopa Uisce HDPE nó soicéad le cineálacha éagsúla agus rátaí sreabhadh leá éagsúla. Déantar an ceangal comhleádaithe a roinnt ina nasc soicéad comhleáite agus nasc cineál diallait comhleádaithe.

Polyethylene pipe jacking flexible connection is a new type of connection developed with reference to the principle of socket-type flexible connection of cast iron and polyvinyl chloride (pvc-u). It is welded at one end of the HDPE Water Pipe with a reinforced polyethylene Mouthpiece.

Socket-type flexible connection is one of the HDPE Water Pipe directly into the tube or pipe fittings in the special socket, through the socket in the lock ring compression pull, rubber seal tight seal, to connect pipe and pipe fittings purposes.

4, HDPE Water Pipe flange connection

Flange connection is mainly used for polyethylene pipe and metal pipes or valves, flow meters, pressure gauges and other ancillary equipment connection. Flange connection mainly by the polyethylene flange connector, steel or aluminum flanges, gaskets or seals, bolts, nuts and other components. Flange connection is through the fastening bolts, nuts, flange connections and flange pieces in close contact to achieve the purpose of connection.

Úsáidtear an comh-aistriú cruach-plaisteach chun píopaí poileitiléine agus píopaí miotail a nascadh le haistrithe fuar nó réamhdhéanta réamhdhéanta de pháirteanna crua-phlaisteacha. Tá fáinní glasála agus rónta ag frith-tharraingt ar fháinní glasála agus rónta ag comhpháirteanna aistrithe cruach-phlaisteacha, de ghnáth is gá feidhmíocht shéalaithe maith agus friotaíocht a tharraingt, tá friotaíocht brú níos mó ná an córas píopaí poileitiléine.

Gnéithe

1. Basic characteristics: high-density polyethylene is an opaque white wax-like material, the proportion of water than the light, the specific gravity of 0.941 ~ 0.960, soft and tough, but slightly harder than LDPE, but also slightly elongated, non-toxic, tasteless.

2. Saintréithe dócháin: is féidir inadhainte, ón tine a bheith ag sruthán, bhí barr an lasair buí, bhí an gorm ag bun, déanfaidh sé leá, leachtach gan sileadh, gan aon deatach dubh, ag an am céanna, nuair a eisíodh an cheist an parailín a dhó An boladh

3. The main advantages: Naisuan Jian, resistant to organic solvents, excellent electrical insulation, low temperature, can still maintain a certain toughness. Surface hardness, tensile strength, rigidity and other mechanical strength are higher than LDPE, close to PP, than PP tough, but the surface finish as PP
