316 Stainless Steel Tube Knowledge - Corrosion Resistance - 316 Stainless Steel Tube Heat Treatment - 316 Stainless Steel Tube Welding
2 316 and 317 stainless steels (see below for properties of 317 stainless steel) are molybdenum-containing stainless steels.
The molybdenum content of 3 317 stainless steel is slightly higher than that of 316 stainless steel. Due to the molybdenum content in the steel, the total performance of the steel is better than that of 310 and 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses.
4 316 stainless steel also has good chloride attack properties, so it is often used in the marine environment.
Corrosion resistance of 316 stainless steel pipe 5 Corrosion resistance is superior to 304 stainless steel and has good corrosion resistance in the production of pulp and paper.
6 And 316 stainless steel is also resistant to the erosion of the ocean and the aggressive industrial atmosphere. Heat resistance of 1600 degrees below the intermittent use and in 1700 degrees below continuous use, 316 stainless steel has good oxidation resistance.
7 In the range of 800-1575 degrees, it is better not to continuously apply 316 stainless steel, but when the 316 stainless steel is continuously used outside this temperature range, the stainless steel has good heat resistance.
8 316L stainless steel has better carbide precipitation resistance than 316 stainless steel and can use the above temperature range.
316 stainless steel tube heat treatment 9 Annealed at a temperature in the range of 1850-2050 degrees, followed by rapid annealing, and then rapidly cooled.
10 316 stainless steel cannot be hardened by heat treatment.
316 stainless steel pipe welding 11 316 stainless steel has good welding performance. All standard welding methods can be used for welding. Welding can be based on the use of 316Cb, 316L or 309Cb stainless steel filler rods or electrodes for welding. In order to obtain the best corrosion resistance, the welded section of 316 stainless steel needs post-weld annealing. If 316L stainless steel is used, post-weld annealing is not required.
12 Typical applications Pulp and paper equipment Heat exchangers, dyeing equipment, film processing equipment, pipelines, materials for the exterior of buildings in coastal areas.
Flexible rubber soft joint is also called rubber joint, rubber flexible joint, soft joint, shock absorber, pipeline shock absorber, shock absorber throat, etc. It is a kind of high elasticity, high air tightness, medium resistance and weather resistance. The pipe joint is a hollow rubber product that acts as a flexible connection between metal pipes
Rubber soft joint products utilize the advantages of rubber's elasticity, high air tightness, medium resistance, weather resistance and radiation resistance. High pressure, high temperature mold vulcanization. It has high internal density, can withstand high pressure, and has good elastic deformation effect. Shock absorption, noise reduction, lightweight, non-toxic.
According to the shape, it is divided into: concentric and same diameter, concentric reducer, eccentric reducer.
According to the structure, it is divided into: single sphere, double sphere, elbow sphere.
According to the connection form, it is divided into: flange connection, threaded connection, threaded pipe flange connection.

The flexible rubber soft joint solves the problem of different diameters when connecting metal pipes, and also has the effect of shock absorption and noise reduction, which can save pipe installation parts and save costs. It has the characteristics of high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration absorption, good noise reduction effect, and convenient installation. It is used in connection with pumps and Valves, pipelines with large vibration, and pipelines with frequent changes in cold and heat.
Rubber soft joint products have high pressure resistance, good elasticity (axial and lateral angular displacement), noise reduction, light weight, shock absorption, easy installation, flexible use, easy replacement and maintenance, and have acid resistance, alkali resistance, oil resistance, etc. Features.
Can be widely used in water supply and drainage, circulating water, HVAC, fire protection, papermaking, pharmaceuticals, petrochemicals, ships, pumps, compressors, fans and other pipeline systems. The ordinary type is used to transport air, compressed air, water, seawater, oil, acid, alkali, etc. at -15℃~120℃. The special type is used to transport the above-mentioned medium or oil, concentrated acid and alkali, and solid materials above -30℃~250℃.
Applicable media: sea water, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam and granular powder.
The normal applicable medium for flexible rubber joints is ordinary water with a temperature of 0-60 °C. For special media such as oil, acid and alkali, high temperature and other corrosive and hard textures, the corresponding special-resistant material rubber joints should be selected. , and cannot be used blindly or generically.
When using or storing the flexible rubber joint, avoid high temperature, ozone, oil and acid-base environment. A sunshade frame should be built for pipes used outdoors or facing the sun and wind, and it is strictly forbidden to expose to the sun, rain, and wind erosion. The surface of the joint is strictly prohibited to be painted and wrapped with thermal insulation materials. Due to the aging problem of rubber products, it should be checked and replaced in time.
