Stainless Steel Pipe Application Requirements
Jul 27, 2022
The car industry
The main use of stainless steel is the exhaust system, accounting for the total amount of automobile stainless steel 1/2 above, 80% for ferritic stainless steel. The exhaust gas produced by the automobile engine flows out of the muffler through the exhaust inlet pipe, front pipe, hose, converter, center pipe and finally. Exhaust system commonly used steel 409L, 436L and so on. Automobile mufflers mainly use stainless steel welded pipes. It is estimated that the stainless steel pipe used by the car accounts for about 1.5% of the whole downstream of the stainless steel pipe consumption, and the use of stainless steel seamless pipe and welded pipe ratio of about 2:1
The petrochemical industry includes the fertilizer industry
The demand for stainless steel pipe is great, the industry mainly uses stainless steel seamless pipe, specifications include: 304, 321, 316, 316L, 347, 317L, etc., the outer diameter in ￠18-￠610, the wall thickness in 6mm-50mm or so (generally choose specifications in φ159mm above the medium and low pressure pipeline), the specific application field is: Furnace tube, material conveying tube, heat exchanger tube, etc.
Water and gas and other fluid delivery
Stainless steel pipe and its water transmission equipment are the most advanced basic water purification materials in the world today, with strong corrosion resistance, which can not be compared with cast iron pipe, carbon steel pipe, plastic pipe, etc.
Water preparation, storage, transport, purification, regeneration, desalination and other water industry best selection of materials. The annual demand is about 25,000 tons.
Equipment manufacturing and maintenance
Annual consumption of stainless steel pipe more than 20,000 tons. This type of industry mainly uses sanitary or antibacterial grade stainless steel pipe. The sanitary seamless tube made of imported SUS304 and 316L can meet the special requirements of various media in food and biopharmaceutical fields. Antibacterial stainless steel has the advantages of stainless steel and good antibacterial properties, in the kitchen equipment, food industry table and utensils, medical instruments, daily life tableware and towel hanging bracket, refrigerator bracket and other fields of increasing demand. Suction straw, especially suitable for
Used for solids such as powder, debris and granular objects
Used of gaseous media.
Used in industrial dust removal and suction equipment, air conditioning and ventilation systems
Used as a durable protective tube
Used for manufacturing machine parts and engineering structures
It is used for all kinds of conventional weapons, gun barrels, and shells. If we compare the living space of a human being to a human body, the pipes laid in the living space are like blood vessels and nerves. Conveying high quality drinking water, the choice of pipe fittings is very important. To this, the author recently visited the concerned experts of stainless steel branch of China special steel association.
The EXPERT THINKS NOWADAYS THE BUILDING USES CONDUIT TO BE CONCEALED PROJECT AND CONDUIT WELL PROJECT MOSTLY, IF TUBE MATERIAL CHOOSES IMPROPER, ACCORDING TO THE EXPERT CALCULATES, WILL CAUSE CONDUIT MATERIAL ITSELF VALUE TO INVESTOR 10~20 TIMES ECONOMIC LOSS. In addition, the selection of pipes is also a barometer of the development and progress of the water industry. The 5 selection principles of water supply pipe: safety, reliability, economy, sanitation, energy saving, sustainable development, which is also the several characteristics of green pipe, only the pipe that can well meet these principles is really good pipe.
The intensity of comparison
The most commonly used stainless steel in the water industry is 304 and 316 stainless steel, which can meet the vast majority of water treatment and transportation conditions.
