Threaded Pipe Coupling Dimensions Chart - Steel Coupling

A threaded coupling (or coupler) (used in piping or plumbing) is a very short length of pipe or tube, with threads at both ends that allows two pipes or tubes to be joined together.

Hebei Sanvo is a quality pipe couplings manufacturer and supplier, and exports various dimensions of steel pipe coupling, including carbon steel pipe coupling, stainless steel pipe coupling, galvanized pipe coupling, black pipe coupling, standard full merchant coupling, standard half merchant coupling, extra heavy full merchant coupling, extra heavy half merchant coupling, API Line pipe coupling, and other threaded pipe couplings.

The Threaded Pipe Coupling Dimensions Chart Is As Follows:

1, Standard Full Merchant Couplings

Merchant Steel Couplings Conforms to ASTM A865, ASME B1.20.1
Size: 1/8''-6''
Notes: 1/8''-2'' Straight Tapped(NPS), 2.5''-6'' Taper Tapped(NPT).
Merchant Couplings in 2'' are available Taper Tapped as special.
Galvanized Couplings are electroplated zinc or hot-dipped zinc;
Black Couplings are phosphate coated or sandblasted.

2, Standard Half Merchant Couplings

Merchant Steel Half Couplings Conforms to ASTM A865, ASME B1.20.1
Size: 1/8''-6''
Notes: 1/8''-1''Taper Tapped(NPT), 1 1/4''-2'' Sraight Tapped(NPS), 2.5''-6'' Taper Tapped(NPT).
Merchant Couplings in 2'' are available Taper Tapped as special.
Galvanized Couplings are electroplated zinc or hot-dipped zinc;
Black Couplings are phosphate coated or sandblasted.
