ASTM A249 TP304L Stainless Steel Welded Tube For Heat Exchanger Conderser High Corrosion Resistance
Yuhong Special Steel has been engaged in austenitic stainless steel and nickel alloy steel (Hastelloy, Monel, Inconel, Inkoloy) seamless welded pipes and pipes for more than 25 years, and steel pipes are sold every year. Over 80,000 tons. Our customers have covered more than 45 countries including Italy, Britain, Germany, the United States, Canada, Chile, Colombia, Saudi Arabia, South Korea, Poland, Singapore, Australia, France, etc.
ASTM A249 TP304L Stainless Steel Welded Pipe is produced to ASTM standard, stainless steel 304L grade and bright annealed, 19.05 mm (0.75 in) outside diameter, 1.25 mm (0.049 in) wall thickness, is a common size for heat exchangers, condensers and other Heating process system.s.
A 249 Tp 304l is a popular grade of low carbon austenitic stainless steel. In general, alloy A249 Tp304l is considered a general-purpose alloy with many favorable properties. One of these properties is its good formability, which is why the alloy can be easily shaped and formed into the specified A249 Tp 304l stainless steel welded pipe. Additionally, ASTM A249 304l Welded Pipe has good weldability and can be welded using conventional practice techniques.
ASTM A249 TP304L Stainless Steel Properties SS 304L is a low carbon 304 austenitic stainless steel, in detail, the carbon content in 304L is up to 0.035%, which can improve corrosion resistance in many applications, 304L mechanical properties include tensile strength up to 483 Mpa, yield point up to 170 Mpa, elongation 35%, hardness minimum 90 (HRB), non-magnetic grade, ideal material for welded pipe.
304l stainless steel welded pipe is made from a low carbon version of grade 304 steel. The material has carbon, manganese, silicon, phosphorus, sulfur and 18% chromium and 8% nickel. Yuhong is a leading manufacturer of 304l stainless steel welded and seamless pipe types. These are strong tubes, but not as strong as the 304. The minimum yield strength of the tube is 170MPa and the minimum tensile strength of the tube is 485MPa.
304l stainless steel pipe suppliers produce high hardness pipes. Due to the reduced carbon content, the material has a Brinell hardness of 201HB and ductility. Tubes can be ERW, welded, seamless, fabricated or LSAW fabricated. These tubes can meet ASTM a213, 249 and 269 specifications. These are some high pressure and high temperature specifications. Therefore, SS UNS S30403 welded pipe is used in heat exchangers, boilers, condensers, superheaters, power generation and oil and gas industry applications where high pressure and high temperature are prominent.
These tubes are available in nominal bore sizes from 1/8" to 30". Stainless steel 304L ERW pipe is available in wall thicknesses ranging from 0.35mm to 6.35mm. There are different schedules for tubes from sch20 to XXS. UNS S30403 SS Heat Exchanger Tubes are designed for heat exchanger applications. The shape of the tubes can also vary, such as round, square, rectangular or hydraulic. ASTM A249 TP 304L Stainless Steel Coiled Tubing is available in lengths ranging from single random, double random to custom lengths. Tubes are available in flat, beveled and threaded end types for different assemblies. Please feel free to contact us for more information on 1.4306 Stainless Steel Tube and prices.

Annealed and Pickled Stainless Steel Welded Pipe A249 welded pipe should be solution annealed after welding. Generally, the heat treatment temperature of austenitic stainless steel is 1040-1150 degrees Celsius. Different grades have different annealing temperatures. This process can remove oxide skin, plain weave and stress relief, making the pipe soft and easy to manufacture. , After annealing, the stainless steel tube should be pickled in an acid mixture to remove the oxide scale, clean the surface, and then form an oxide film to protect the tube under passivation conditions. Bright Annealed Stainless Steel Welded Pipe Bright Annealed (BA) finish is another surface condition that increases the brightness level of the surface of the tube for a cleaner surface and is a perfect addition to the annealed passivation finish.
