Q345B cold drawn square tube

Q345B pipe ya viwanja vya baridi ina utulivu mzuri na ni muundo wa pamoja.The epoxy resin coating center is reinforced welded steel pipe. Muungano wa muundo huu unaruhusu pipe ya chuma kuwa na ustawi bora.The pipe is not only not easy to corrode in the face of various corrosive media, but also has a relatively stable expansion coefficient, so the cold drawn square pipe is not easy to deform after use and can effectively extend the service life of the pipeline system.
