China Pipe Coupling Manufacturers Carbon Steel Merchant Coupling Galvanized Extra Heavy Full Merchant Coupling Conforms To ASTM A865, ASME B1.20.1
Galvanized Extra Heavy Full Merchant Coupling Description:
Full merchant couplings are available in black, galvanized, and stainless steel materials. Full merchant couplings are used when a stronger coupling fitting is needed. For example, you can use a full merchant coupling in a drop pipe that’s in a water well because it would be holding the weight of the pipe, water, and the submersible pump. If an even stronger coupling is required, there are drop pipe couplings available that are specific for these applications.
This extra heavy full merchant coupling is furnished for the extra strong and double extra strong pipe. All are taper-tapped.
And galvanized couplings are electroplated zinc or hot dipped zinc, and galvanizing can increase the corrosion resistance of the steel pipe coupling and prolong the service life.
