What is the difference between a flexible pipe and a rigid pipe? What types of pipes are used for drainage pipes, heat pipes and gas pipelines?
However, these three tubes have good seismic performance, strong sealing, construction is simple, easy maintenance, the use of reliable and so on, it is also known as the cast iron pipe Which W-type cast iron pipe is subdivided into W-type cast iron pipe and W1-type cast iron pipe, the main difference between the two is the difference between the wall thickness, because the difference between the north and south temperatures, the northern cold weather on the pipe requirements higher , So in general W-type cast iron pipe is mainly used for the north, and W1-type cast iron pipe is mainly used for the South side
Can not do, according to the construction map can be
Stainless steel corrugated hose is not easy to aging, the two ends of the connection is more difficult to fall off, the safety performance is more reliable
From the environmental point of view and save the cycle of insulation coating is good, insulation coatings can be divided into internal and external insulation and other products
