Installation & Use
Before installation, check the flange surface, bolt holes, and sealing face for galvanizing layer damage, scratches, or contamination; clean the welding end and flange sealing face thoroughly. Use gaskets compatible with carbon steel and the working medium; tighten bolts evenly and symmetrically to ensure uniform pressure and reliable sealing. Conduct a pressure test after installation to confirm no leakage before formal operation. Avoid damaging the galvanizing layer during installation.
Precautions
Store in a dry, clean, and ventilated warehouse to avoid moisture, corrosion, and damage to the galvanizing layer; handle with care during transportation to prevent collision and scratch. Use within the rated pressure (Class 150) and temperature range; avoid overloading or improper installation. Professional welding and installation personnel are recommended to ensure the welding quality and galvanizing layer integrity.
