Full Merchant couplings are available in black, galvanized and stainless steel. Full Merchant couplings are used when stronger coupling fittings are required. For example, you can use an Full Merchant coupling in the downpipe of a well because it can hold the weight of the pipes, water and submersible pump. If a stronger joint is required, drop tube joints specifically designed for these applications are available. Black all Full Merchant are also available for applications requiring welding.
Note that Full Merchant couplings should never be used as fittings in plumbing systems where a watertight seal is critical. However, tapered Full Merchant are available for such applications.
Half merchant couplings are half the size and are used to provide threaded outlets on the flat face of metal tanks. The tank is drilled with holes/ports and the coupling halves are welded to the tank centered on the ports. One half of the coupling goes all the way through the threads, but is squared off at one end to aid in welding to the tank.
Half merchant couplings are designed for welding and are therefore only available in black finish. This means they are not available with a galvanized finish, as welding galvanized fittings produces fumes which are harmful to health.
Products are used in fire protection system, water system, HVAC system, plumbing, gas system, irrigation system, etc.These products are used in many projects , such as Beijing Airport, Shanghai World Trade Center, Canton Tower and other famous landmark projects
