Thin-walled stainless steel seamless pipes refer to stainless steel pipes with a ratio of wall thickness to outer diameter not greater than 6%. Mainly used for building water supply pipes.
Construction and installation of thin-walled stainless steel seamless pipe
1) Thin-walled stainless steel pipes and fittings should not be in direct contact with cement, cement mortar and concrete. When the pipeline is concealed, the anti-corrosion tape should be wrapped around the outer wall of the pipe or a plastic-coated thin-walled stainless steel pipe should be used.
2) When cement mortar is used to fill the concealed pipeline, thermal insulation materials should be used to ensure that there is a gap between the cement mortar and the pipe. So that the hidden tube can be freely stretched.
3) The plastic-coated thin-walled stainless steel pipe should be selected for burial, which can avoid acid-base corrosion on the outer wall of the pipe or damage to the pipe by sharp and hard debris.Other wrapping materials can also be used for anti-corrosion measures, such as wrapping two layers of polyethylene tape or two layers of vinyl chloride tape, wrapping two layers of asphalt paint (or epoxy resin), and glass fiber plastic cloth for anti-corrosion.
4) The pipeline should be reasonably equipped with telescopic compensation devices and brackets (fixed brackets and movable brackets) to control the expansion direction or compensation of the pipeline. When the length of the straight line section of the hot water thin-walled stainless steel pipe for exposed or non-buried hidden application exceeds 10~15m, compensation measures should be taken in the axial direction of the pipe. When the nominal diameter is greater than 50mm, stainless steel wave expansion joints or stainless steel linear temperature compensators should be installed.
5) Anti-condensation measures should be taken for thin-walled stainless steel pipes for water supply in buildings exposed to the outside world, and thin-walled stainless steel pipes for hot water should be insulated.
6) The pipes and fittings should be supplied by the supplier uniformly. It is not suitable for welding between different grades of stainless steel.
7) The pipes and fittings are thin-walled. When connecting with accessories such as silk valves, water nozzles, water meters, etc., the thin-walled stainless steel pipe should not be threaded, but should be transitioned through adapters and other wire-connected accessories.
8) Oil pollution will deteriorate the rubber sealing ring, and sharp objects collide with pipes and fittings will cause water leakage, so be careful during construction.
9) After the pipeline is installed and the pressure test is qualified, it should be rinsed with low chloride ion water and disinfected with 0.03% potassium permanganate aqueous solution
Advantages of thin-walled stainless steel seamless pipes
1. Good corrosion resistance
2. Material saving
3. Strong impact resistance
4. Good hygiene
5. Small thermal conductivity
6. The inner wall of the joint is unobstructed
7. Simple construction
8. High cost performance
9. Beautiful product appearance
