Manufacturing of Casing Pipe

The production of casing pipes are smelting raw material in electric furnaces, treated with synthetic slag and cast by continuous casters. This raw material making process guarantees the component of chemical is pure steel, given the phosphor and sulfur contents. This provides highly ductile, malleable and corrosion-resistant pipes, which can operate at low temperatures in a number of corrosive media. Steel grades and heat-treatment regime application allows production of high-strength pipe.

Specifications of Casing Pipe

Casing pipes should have minimum yield strength of 35,000 psi. Casing pipes need to have smooth walls and be exceptionally straight and round. Casing pipe and joint construction should be of uniformly thick steel to avoid any matter leaking from the casing. The outside diameter, size and wall thickness should conform to ASTM Designation A252. Use pull-on or wrap-around rubber varieties of “casing end seals” to seal the ends of the steel casing pipe. Apply corrosion-proofing water-based paint to the exterior pipe surface to safeguard against atmospheric corrosion during shipping and storage.
