What are the differences between cast iron pipes W and A?
Cast iron drainage pipe generally divided into three categories, namely W type socket cast iron pipes, cast iron pipes of A type, B type cast iron drainage pipe, the three pipes have good seismic performance, strong sealing performance, simple construction, convenient maintenance, reliable use, so it is also called the cast iron pipe for earthquake.
W type socket cast iron drainage pipe made of stainless steel flexible clamp connection in the construction of the installation; A type cast iron drainage pipe with flexible flange and sealing ring connection in the construction of the installation; B type cast iron drainage pipe comprehensive advantages of W type and A type cast iron drainage pipe, straight pipe part adopts W type bearing mouth of pipe, pipe fittings with double flange structure;
W cast iron pipe is subdivided into W cast iron pipe and W1 cast iron pipe, the difference between them is the difference between the wall thickness. Because of the cold weather, the requirements for pipes are higher. The W cast iron pipes are mainly used in the north, while the W1 cast iron pipes are mainly used in the south.
Type W: combination of both advantages of the connection type A interface has the advantages of high strength and convenient installation, because of the use of W type straight pipe and reduces the material cost and can be coupled with the design structure of the B type pipe is more compact than the A type pipe, saving installation space.
