Materials and Surface Treatment
We utilize premium pliable cast press as our base fabric. This press experiences a extraordinary warm treatment handle in our 100-ton normal gas tempering ovens. The treatment changes the fragile carbon into nodular graphite, making a pliable, shock-resistant material.
Our hot-dipped galvanizing handle drenches each fitting in liquid zinc at controlled temperatures. The zinc metallurgically bonds to the press surface, making numerous defensive layers. This coating regularly measures 70-85 microns thick, giving long-lasting assurance against dampness, chemicals, and climatic corrosion.






Application Areas

Perfect for civil water conveyance, building plumbing, and water system networks.
Gas Pipeline Projects
Suitable for characteristic gas, LPG, and compressed discuss dispersion systems.
Oil and Petroleum
Works well in low-pressure oil exchange and capacity office connections.
Industrial Manufacturing
Ideal for manufacturing plant compressed discuss lines, coolant frameworks, and handle liquid handling.
Marine Environments
The galvanized coating performs excellently in coastal and high-humidity conditions.






Installation Instructions
Preparation
Clean the pipe strings altogether. Evacuate any flotsam and jetsam, ancient sealant, or corrosion.
Thread Sealant Application
Apply PTFE tape or affirmed pipe string sealant to the male strings. Wrap tape clockwise when seeing the string end.
Hand Tightening
Thread the fitting by hand to begin with. This guarantees legitimate arrangement and anticipates cross-threading.
Wrench Tightening
Use two torques for the last fixing. One torque holds the fitting body whereas the other turns the association. Do not over-tighten, as this can harm the threads.
Pressure Testing
After establishment, weight test the framework some time recently putting it into service.
