It is suitable for transportation of pressure water, such as water and gas. The material of sand casting centrifugal cast iron pipe is grey cast iron.
1.2 continuous cast iron pipe
It is suitable for transportation of pressure water, such as water and gas. Continuous cast iron pipe, continuous casting grey cast iron pipe.
2 drain cast iron pipe
General drain pipe and fittings for cast iron bearing. Flexible anti-seismic interface drainage cast-iron pipe. Excellent flexibility and flexibility under internal pressure. Can be accustomed to larger axial displacement and lateral deflection, the cast iron pipe rubber ring sealing, bolt fastening. The utility model is suitable for indoor drainage pipes of high-rise buildings and is particularly suitable for earthquake areas. Three 、 nonferrous metal tube
Aluminum alloy containing 98% pure aluminum and aluminum alloy as the main body, with copper, magnesium, manganese, zinc and chromium. Aluminium and aluminium alloy tubes are formed by drawing or kneading industrial pure aluminium or aluminium alloy. Aluminum has better acid and corrosion resistance.
1. aluminium and aluminium alloy tube aluminium and aluminium alloy.
Known as brass or copper brass tube is made of brass, brass and brass in general.
2. copper and copper alloy tubes and copper tubes are mainly made of pure copper and phosphorus deoxidized copper.
3. lead and lead alloy tubes four plastic pipes
Plastic pipes are usually made of plastic resin, and are involved in stabilizers, lubricants and so on. Building engineering has been more and more widely used. Water, water supply, piping, drainage, exhaust and sewage cleaning pipes, underground drainage systems, storm pipes, pipe fittings for wire equipment and so on, are mainly used for house building. By plastic method, in the tube machine by kneading processing. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, simple processing, easy construction and so on
