steel sleeve for cold rolling mill quenching process: Pit quenched with water quenching and oil cooling.
We use advanced process of smelting and casting dedicated to ensure the steel sleeve chemical composition is reliable, accurateand and has the same properties. Centrifugal casting is dedicated to ensure internal and external surfaces of sleeve have no defects such as crack, slag, blowhole, blister, etc. The heat treatment process will make sure the mechanical performance of sleeve. With the special machining tool and rational process the sleeves have high performance of concentricity, cylindrical, symmetry and balancing.

Waterproof rigid stainless steel pipe sleeves for building concrete walls

Application of pipe sleeves

When passing steel, cast iron, copper or plastic pipes through walls, ceilings or floors, waterproof sleeves serve as a protective conduit. The pipe passes through the inside of the sleeve.

Stainless steel pipe sleeve benefits

  • Save time and money for civil works
  • Positive hydrostatic sealing
  • Long seal life
  • Seals and pipe
  • Corrosion protection
  • Compensates for misalignment
  • Absorbs shocks, sound and vibration
