Content

CL3000 threaded couplings are used to connect pipes in high pressure environments.ASTM A105 forged pipe fittings are carbon steel pipe fittings,for butt welded fittings in same material,the specification in American Standerd is ASTM A234 WPB.

 

Types of Threaded Couplings:

Full Coupling: Both ends of the full thread coupling are threaded.

Half Coupling: One end of a half thread coupling is threaded and the other end is welded.

 

Shapes:

Straight:CouplingS with the same diameter at both ends.

Reducing: The two ends of the coupling have different sizes.

 

Threaded Types:

NPT PT BSPP BSPT PF

 

PRESSURES

Threaded pipe fittings have 3 grades of pressures to satisify different applications: CL2000,CL3000,CL6000,among these,the THD fittings of CL3000 is the most commonly chosen.

 

Carbon Steel Galvanized VS Stainless Steel

Carbon steel pipe fittings could be galvanized to enhance the anti corrosion function,it could be equivalent to stainless steel in some applications.
