430 stainless steel pipe is used for building decoration, fuel burner parts, household appliances and household appliances. 430F is a steel with free cutting property added to 430 steel, mainly used for automatic lathes, bolts and nuts. 430LX adds Ti or Nb to 430 steel to reduce the content of C, which improves the processability and welding performance. It is mainly used in hot water tanks, hot water supply systems, sanitary appliances, household durable appliances, bicycle flywheels, etc.
304L stainless steel pipe is mainly used in automobile accessories, hardware tools, tableware, cabinets, medical appliances, office equipment, weaving, handicrafts, petroleum, electronics, chemicals, textile, food, machinery, construction, nuclear power, aerospace, military and other industries.
Stainless steel pipe is mainly used for three purposes:
1. Stainless steel decorative pipe
In fact, it is a stainless steel pipe used for decoration, which is mainly widely used in stainless steel anti-theft windows, stair guardrails, stair handrails, etc.
2. Stainless steel industrial pipe
It is divided into seamless pipe and welded pipe.
Scope of application: due to the thin stainless steel welded pipe and good surface treatment effect, it is mainly used for architectural decoration products, civil decorative art stainless steel products, etc. The stainless steel industrial pipe has thick wall, uneven surface and strong bearing capacity. It is mainly used to make large size, high strength, high toughness, mechanical systems and other products.
3. Stainless steel product pipe
Stainless steel product pipe refers to the stainless steel pipe specially customized by the stainless steel pipe manufacturer because the ordinary stainless steel decorative pipe does not meet its use requirements.
2507 stainless steel pipe is used in oil and natural gas industry; Offshore stone skyshatter oil platform (heat exchanger pipe, water treatment and water supply system, fire protection system, water spraying system, water stabilization system; petrochemical equipment; desalination (desalination) equipment (and high-pressure pipe and seawater pipe in the equipment). Mechanical and structural components that require both high strength and high corrosion resistance: fuel (waste) gas purification equipment.
201 stainless steel pipe is mainly used for decorative tubes, industrial tubes and some shallow stretched products. Such as: oil waste gas combustion pipeline; Engine exhaust pipe; Boiler shell, heat exchanger and heating furnace components; Silencing parts for diesel engine; Boiler pressure vessel; Chemical transport vehicle; Expansion joint; Spiral welded pipe for gas furnace pipe and dryer, etc.
310S stainless steel pipe is widely used in kiln, high-temperature furnace, boiler, furnace liner high-temperature equipment, such as kiln car, boiler liner, high-temperature furnace, high-temperature furnace tube, combustion machine liner, etc. It can be used for high-temperature equipment. The product is resistant to high temperature and heat. 310s stainless steel plate has good creep strength and can work continuously under high temperature. The working temperature of 310S stainless steel is 1200 ℃, and it can work continuously at 1100 ℃. It is mainly used to manufacture high temperature exhaust pipe, high temperature furnace, high temperature furnace liner, crematory furnace and other steel grades requiring heat resistance, as well as high temperature and high temperature contact parts.
904L stainless steel pipe (super austenitic stainless steel) is a high alloyed austenitic stainless steel with very low carbon content. It has good corrosion resistance in dilute sulfuric acid and is specially designed for environments with severe corrosion conditions. It has high chromium content and sufficient nickel content. The addition of copper makes it have strong acid resistance, especially high resistance to chloride interstitial corrosion and stress corrosion cracking. It is not easy to appear corrosion spots and cracks. Its pitting resistance is slightly better than that of other steels. It has good processability and weldability, and can be used for pressure vessels.
Use of 2205 stainless steel pipe: 1. The heater is generally used in the oil refining unit; 2. Chemical plant equipment pipeline; 3. Fast cooling cylinder for solid solution used in textile industry; 4. Seamless steel pipe for heat exchanger and condenser. 5. High pressure seamless steel pipe for food (gb-2000) is a high-quality carbon structural steel and alloy steel seamless steel pipe suitable for chemical equipment and pipes with working temperature of - 40~400 ° C and working pressure of 10~30ma. 6. Seamless steel pipes for geological drilling and oil drilling control. 7. Cracking pipe for petrochemical industry is used to transport high-temperature and high-pressure fluid on fertilizer equipment.
API 5L pipe is carbon steel pipe used for oil and gas transmissions, it includes the pipes manufactured in seamless and welded (ERW, SAW). Materials covers API 5L Grade B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1 & PSL2 onshore, offshore and sour services.
