Series of Airtight & Protective Airtight Wall Penetrating Pipes and Embedded Pipes

Remove rust from embedded pipe fittings and apply two coats of red lead anti-rust paint on the inner surface. Embed the fittings into walls during civil construction.

Weld the airtight rib to the short pipe before embedding. Full penetration welding is required for joints between pipes, pipes and flanges, as well as pipes and airtight ribs to ensure tight sealing.

Type I is designed for pipe connection at both ends; Type II for pipe connection at one end only.
