What are the characteristics of Best Price Aisi 304 Stainless Steel Coil Tube? How about weldability, corrosion resistance, polishing performance?
Best Price Aisi 304 Stainless Steel Coil Tube is often used in daily life and industrial production, so what are the characteristics of Best Price Aisi 304 Stainless Steel Coil Tube? Today I will take you to find out:
1. Corrosion resistance
Most stainless steel products require good corrosion resistance. Some foreign merchants also do corrosion resistance tests on the products: use NACL aqueous solution to heat to boiling, pour the solution after a period of time, wash and dry, and weigh the weight loss to determine the corrosion resistance. Corrosion degree (Note: When the product is polished, the Fe content in the abrasive cloth or sandpaper will cause rust spots on the surface during the test).
2. Weldability
Different product uses have different requirements for welding performance. A class of tableware generally does not require welding performance, and even includes some pot enterprises. However, most products require good welding performance of raw materials, such as second-class tableware, thermos cups, steel pipes, water heaters, water dispensers, etc.
3. Polishing performance (BQ property)
At present, stainless steel products are generally polished during production, and only a few products such as water heaters and water dispenser liner do not need polishing. Therefore, this requires that the polishing performance of the raw material is very good.
1. The stainless steel pipe must be cleaned before installation.
2. When the pipeline is long or the temperature of the conveying medium is high, a compensator should be installed in an appropriate position. The commonly used compensators are square and waveform, and the selection should be based on the working pressure and temperature.
3. The stainless steel pipe is not allowed to come into contact with the carbon steel bracket, and a stainless steel sheet or a plastic or rubber gasket without chloride ions should be placed between the bracket and the pipe.
4. When using the compression connection, special pipe fittings should be used for connection, and insulation should be placed between the pipe fittings and the stainless steel pipe, and plastic, rubber or asbestos rubber sheets that do not contain chloride ions can be used.
5. When the stainless steel pipe passes through the wall and floor, a casing should be installed. The gap between the casing and the stainless steel pipe should not be less than 10mm, and insulation should be filled in the gap. Debris filling.
6. The quality acceptance of sub-projects shall meet the following requirements:
① The inspection batches included in the sub-projects shall meet the requirements of qualified quality.
②Have complete construction operation basis and quality inspection records.
②Have complete process handover and acceptance records between relevant majors and major processes.
