ASTM A358 EFW PIPES
PetroSan Oilfield Engineering Co.—previously known as PetroSan—was founded. It is the best fabrication and manufacturing firm in South Asia, renowned for its exceptional quality and punctual delivery. We are the industry pioneers in ASTM A358 EFW stainless steel welded pipes. Our extensive experience and specific skills. Our superior products set the standard for other producers.
PetroSan stainless steel EFW welded pipes with the ASTM standard of A358 tp304/304l and a358 tp316/316l NACE MR0175, IGC Tested pipes is the latest in the series of value-added, high performance, innovative products from Total Piping Solutions.
The PetroSan Oilfield Engg. Co. produced ASTM A358 EFW stainless steel pipe is a high-quality pipe suitable for corrosive or high-temperature service, or both, or for general applications ¹. The pipes are sorted into five different classes, ranging from double-welded to single-welded pipes, with varying levels of radiography ¹. Here are the five classes of pipes under the ASTM A358 specification :
– Class 1: Double welded by processes employing filler metal in all passes and completely radiographed.
– Class 2: Double welded by processes employing filler metal in all passes with no radiography.
– Class 3: Single welded by processes employing filler metal in all passes and completely radiographed.
– Class 4: Single welded except that the weld pass exposed to the inside pipe surface may be without the addition of filler metal.
– Class 5: Double welded by processes employing filler metal in all passes and spot radiographed.
The ASTM A358 EFW stainless steel pipe is available in various sizes, ranging from 1/8 inch to 30 inches in diameter, and comes in different thicknesses. The pipe’s dimensions and weights are determined by ANSI specifications, and it is suitable for use in various industries, including construction, oil and gas, and chemical processing.
Different standards, including ASTM, DIN, JIS, GB, AISI, and other international standards, apply to ASTM A358 pipe. The electric fusion welding process is used to create the ASTM A358 Class 1 EFW Pipes. The composition of the materials for the ASTM A358 TP304 includes silicon, sulfur, phosphorus, 8% nickel, and 18% chromium. The composition of the far more durable A358 316L includes molybdenum. The material is resistant to corrosion by chloride ions because of the molybdenum component. Because of its strength and affordability, the A358 304 is the most popular material. There are eight to seventy-two inch sizes available for the ASTM A358 stainless steel pipe. The pipes’ thicknesses vary from 3 to 60 mm. The length of the ASTM A358 uns S31254 varies up to 6 meter.
TP304L Stainless Steel EFW, ASTM A358 Pipes can have a variety of finishes, including electropolished, pickled, BA, and No 4. Class 2 and ASTM A358 TP304 CL1 differ slightly mechanically. While class 2 has superior mechanical qualities and is utilized in certain applications, class 1 ASTM A358 TP304L is the material that is used most frequently. The food and beverage sector, the building industry, nuclear applications, boilers, and the petroleum and petrochemical industries all employ the ASTM A358 TP316l. Additionally, there are many pressure classes for the ASTM A358 TP316L CL1, which are divided into schedules 10 through 160. There are lower carbon variants of both the 304 and 316 materials. Better welding capacities are made possible by the reduced carbon concentration.
