China Carbon Steel Coupling Manufacturer Steel Merchant Coupling Black Steel Full Merchant Coupling Used Often In Low-Pressure Piping Situations
Black Steel 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.
Please note that full merchant couplings should never be used as a pipe fitting in a plumbing system where a watertight seal is critical. However, taper-tapped merchant couplings would be acceptable to use for this type of application.
And the black carbon steel pipe, the original material of the black steel pipe coupling, has been sandblasted or coated to enhance its corrosion resistance.
