Welding: Electric Resistance Welding (ERW), high-frequency welding process. The weld seam shall be 100% inspected by Eddy Current Testing (ET) and shall be free from cracks and incomplete penetration.
Galvanizing: The galvanized coating thickness shall be not less than 85μm (double-sided). The surface shall be free from "black ash" defects. Residual stress shall be controlled to prevent the risk of hydrogen embrittlement.

Applicant Field

Indoor water supply pipes are commonly used for branch water supply in multi-story residential buildings and office buildings, connecting faucets, water heaters, and other terminal water devices in kitchens and bathrooms. They can also serve as building branch pipes for secondary water supply in residential communities, suitable for low- to medium-pressure water supply systems.
Heating Pipes. Used for the branch pipes of low-temperature hot water heating systems in residences and factories, transporting hot water for circulation and heat dissipation; they can also serve as connecting pipes for radiators, with the galvanized layer preventing internal rust and blockage.
Agricultural Irrigation and Aquaculture. Main pipes for drip and sprinkler systems in agricultural greenhouses, transporting irrigation water; aeration and water exchange pipes in aquaculture ponds, resistant to corrosion in humid environments.
The support columns for outdoor billboards and signs combine strength with rust resistance.
The inlet and outlet pipes of small wastewater treatment equipment convey low-concentration sewage or clean water.
