For 304 stainless steel pipe, people are familiar with it because of its wide application, but the installation of thin-walled stainless steel pipe should meet certain standards to ensure the use efficiency of thin-walled stainless steel pipe in the future. Double clamp pipe fittings, and thin-walled stainless steel pipes for industrial water purification system of the whole house. Next, we will discuss the installation standard of pipe fittings.
1. 304 stainless steel water pipe shall not be in direct contact with cement, cement mortar and concrete. When the pipeline is concealed, anti-corrosion tape shall be wrapped on the outer wall of the pipeline or plastic coated stainless steel pipe shall be used.
2. When the cement mortar is used to fill the buried pipeline, the thermal insulation material shall be used to ensure that there is a gap between the cement mortar and the pipeline. Make the concealed pipe flexible.
3. The plastic coated thin-walled stainless steel (316) pipe is suitable for burying, which can avoid the acid-base corrosion of the outer wall of the pipe or the damage of the pipe caused by sharp and hard impurities. Other packaging materials can also be used as anti-corrosion measures, such as packaging two layers of polyethylene or two layers of vinyl chloride tape, packaging two layers of asphalt paint (or epoxy resin), glass fiber plastic cloth anti-corrosion.
4. 304 stainless steel water pipe shall be reasonably equipped with expansion compensator and bracket (fixed bracket and movable bracket) to control the expansion direction or compensation of the pipe. When the length of the straight-line section of open laid or non buried hot water stainless steel pipe exceeds 10-15m, axial compensation measures shall be taken. When the nominal diameter is greater than 50mm, stainless steel wave expansion joint or stainless steel linear temperature compensator shall be installed.
5. Anti condensation measures shall be taken for pipe fittings, and hot water rust pipes shall be insulated.
6. Pipes and fittings shall be provided by the supplier. It is not suitable for welding different grades of stainless steel.
7. Pipes and fittings are thin-walled. When it is connected with accessories such as screw valve, water nozzle and water meter, it shall not be sleeved on thin-walled stainless steel pipe, but shall be transited through metal wire connector such as switch connector.
8. Oil pollution will make the rubber seal ring deteriorate, and sharp objects will collide with pipes and pipe fittings, which will cause water leakage. Therefore, we must pay attention to the construction.
9. After the pipeline is installed and the pressure test is qualified, it should be washed with low chloride ion water and disinfected with 0.03% potassium permanganate solution.
Stainless Steel Pipe-Encyclopedia
304 and 316L stainless steel materials are the only health materials that can be implanted into human body, so for water supply pipes, stainless steel pipes are the most beneficial to health. In the immersion water test, all the indicators meet the requirements of the relevant national drinking water standards. Stainless steel pipeline has smooth inner wall, no fouling, no bacterial contamination, anti-bacterial, anti-seismic, anti-tension, high pressure and high temperature resistance, no need to worry about water quality, and can prevent secondary pollution of water.Thin wall stainless steel water supply pipe is recognized as one of the best pipes with comprehensive properties
Wide application of stainless steel pipe
304, 316 L thin-walled stainless steel water pipes and pipe fittings series products are widely used in star hotels, medical and health, fire protection, housing, water, food, beverage, schools, airports, subways, high-speed rail, industry, education, ships, industrial desalination projects, drinking water, direct drinking water, cold and hot water, gas and other system fields of large and medium-sized construction projects, and the product sales network has been widely spread It has been exported to Europe, Southeast Asia and other countries and regions, and has established partnerships with many enterprises around the world, with a very broad prospect.
