Carbon steel equal tee

Carbon steel equal diameter tee is an important and large amount of pipe fittings in petroleum and chemical pipeline engineering.
DETAILS:

Carbon steel equal diameter tee is an important and large amount of pipe fittings in petroleum and chemical pipeline engineering. At present, cast tee, forged tee, t-welded tee and extruded tee are mostly used in China's pipeline engineering. Large amount of repair welding is often required in the installation process, which directly affects the progress of the project, and the defects of cast tee are not easy to inspect Leakage accidents often occur after the project is put into operation, so it is not suitable to be used in petroleum and chemical pipelines.

Carbon steel equal diameter tee is an elbow formed by hot pressing or forging. Its connection form is directly butt welding the tee with steel pipe. The main manufacturing standards of butt welded tee are GB / t12459, GB / T13401, ASME b16.9, sh3408, sh3409, Hg / t21635, Hg / t21631, SY / t0510.
