Insulator for separating sections of underground metal gas pipe - prevents corrosion due to currents from household appliancesThe insulator has an inner insulating piece (3) connecting the two screw connectors (1,2) of the two sections of pipe being joined. An outer insulating piece (4) enclose...
The traditional metal pipe generally needs complicated preservative treatment before laying the underground pipes. Even in neutral and non-corrosion soil, the average life of traditional metal pipe is only 10 years. PE flexible pipeline, with PE100 as its outer ...

At very high gas velocities, an annular pattern is observed whereby parts of the liquid flow along the pipe and other parts as droplets entrained in the gas flow. In the gas–liquid interface, especially for sufficient high gas velocity, there may be large amplitude waves that break up ...
A combination device which is inserted through a house wall to bring gas inside it has a main steel through-pipe with gas-tight plastic covering, a tap on the inside end, a connection on the outside end, and a safety device to prevent the pipe from being drawn outside. From the tap ...
