Universal Joint

There are so many way to join the HDPE pipe we can find out on the internet.

As our client frequently ask question, herewith we discuss about universal joint,the way to join HDPE pipe with almost all kind of pipe material.

Commonly there are so many kind to join the HDPE pipe, but since today we founf that only two popular way to do HDPE pipe to other pipe material join. Other pipe material here means kind of PVC pipe, PPR pipe, Steel pipe, Galvanize pipe and some more.

Here is the two popular kind of universal joint:

Stubflange joint means flange to flange joint. Using stub end as the flange holder then bolt and nut to lock the joint. Kind of simple joint and very strong joint. Provide stub flange to each end of the pipe. Remember to insert a gasket or rubber packing between the joint before tighten the bolt and nut.
