HDPE Water Pipe Acid And Alkali Resistance, Organic Solvents

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 priključek za vodno cev

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.

2, taljeni priključek HDPE za vodovod

Taljena povezava je vgrajena uporovna žica s posebnim varovalnim delom povezave s cevjo v tesnem stiku z močjo, prek vgrajenih uporovnih žic grelnih priključnih delov, tako da se integracija, dokler se ne ohladi. Stopljena povezava se lahko uporablja za priključitev na HDPE vodovodne cevi ali priključke z različnimi vrstami in različnimi stopnjami pretoka taline. Taljena povezava je razdeljena na taljeno vtičnico in taljeno sedlo.

3, pe socket type flexible connection

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.

5, HDPE Water Pipe of the steel-plastic transition joints connected

Jekleno-plastični prehodni spoj se uporablja za povezovanje polietilenskih cevi in ​​kovinskih cevi s hladnimi ali drugimi montažnimi jekleno-plastičnimi prehodnimi spoji. Prehodni zglobi iz jeklene plastike imajo zaporne obroče in tesnila proti vlečenju, običajno zahtevajo dobro tesnjenje in odpornost proti vlečenju, odpornost na tlak je večja kot pri sistemu polietilenskih cevi.

Lastnosti

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. Combustion characteristics: flammable, from the fire can continue to burn, the top of the flame was yellow, the bottom was blue, burning will melt, a liquid dripping, no black smoke, at the same time, issued when the issue of paraffin burning The smell

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
