ASTM A 234 Carbon Steel Pipe Fitting Summary Data Sheet
Sunday, 01 April 2018
Even with all the advances in technology today, the wholly welded piping system has for decades remained the best choice for use in high pressure and high temperature application. Many piping jobs in schools, industrial plants, refineries and factories have benefited from the inherent advantages of a completely welded system. It becomes a closed container

API 5CT N80 Length Range R3 Casing Pipe
Wednesday, 21 March 2018
API-5CT N80 oilfield casing pipe contains N80-1 and N80-Q types. Those two materials are absolutely consistent regarding the chemical composition and mechanical attributes, they are just various in the heat treatment. During heat treatment, N80-1 steel is treated by normalizing and tempering, while N80Q steel is treated by quenching and tempering. Therefore, the collapsing strength
