Construction Guide
① Check thread integrity and remove impurities before installation.
② When using pipe wrenches or chain clamps, add a protective shim to prevent coating damage.
③ It is recommended to use PTFE raw material tape, wrapped in the same direction as the threads.
④ Control the tightening torque within the standard range to prevent coating cracking.
Quality Verification
Substrate chemical composition analysis (tested per batch)
Coating thickness measurement (20-25μm uniform layer)
240-hour acidic salt spray test (pH 3.5)
2500-cycle pressure test with no leakage
