Brief:ASTM A335 Grade P22 seamless pipe is a chromium-molybdenum (2.25Cr–1Mo) alloy steel pipe designed for high-temperature and high-pressure service. It is widely used in industries requiring reliable performance under elevated temperature conditions, such as power generation and petrochemical processing.
Brief:ASTM B444 UNS N06625 tube (commonly known as Alloy 625) is a high-performance nickel-chromium-molybdenum alloy tube designed for extreme corrosion and high-temperature environments. It offers outstanding strength, oxidation resistance, and corrosion resistance, making it suitable for the most demanding industrial applications.
UNS N06625 is strengthened by niobium (Nb) and molybdenum, providing excellent mechanical properties without the need for heat treatment. Its superior resistance to pitting, crevice corrosion, and stress corrosion cracking makes it a preferred material in aggressive chemical and marine environments.
Brief:ASTM A312 Grade TP304L pipe is a low-carbon austenitic stainless steel pipe widely used for its excellent corrosion resistance, weldability, and versatility. The “L” grade indicates reduced carbon content, which helps prevent intergranular corrosion after welding, making it especially suitable for fabricated piping systems.
Brief:ASTM A270 Grade TP316L stainless steel sanitary tubing is specifically designed for high-purity and corrosive-resistant applications in the pharmaceutical, biotechnology, food and beverage, and cosmetic industries. Manufactured in accordance with ASTM A270 standards, this tubing offers excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, thanks to its low carbon content (0.03% max) and molybdenum addition.
Brief:The ASTM A358 TP304L (UNS S30403) is an Electric Fusion Welded (EFW) austenitic stainless steel pipe designed for high-temperature and general corrosive service. The "L" grade indicates a low carbon content (≤0.03%), providing superior resistance to intergranular corrosion after welding without requiring post-weld heat treatment. This standard covers Class 1 through Class 5 pipe based on radiographic examination requirements, offering flexibility for various application criticality levels.
Brief:ASTM A928 Grade UNS S31803 duplex stainless steel pipe is a high-strength electric-fusion-welded (EFW) duplex stainless steel pipe designed for corrosive and offshore service environments. Commonly known as Duplex 2205, features a balanced ferritic-austenitic microstructure (approximately 40–50% ferrite / 50–60% austenite), delivering high strength and excellent resistance to chloride-induced stress corrosion cracking (SCC), pitting, and crevice corrosion.
Brief:API 5L Grade B PSL1 Line Pipe is a carbon steel pipe manufactured in accordance with the American Petroleum Institute (API) 5L specification, serving as the fundamental grade for pipeline transportation systems.
Brief:API 5CT H40 is a foundational grade of oil country tubular goods (OCTG) as defined by the American Petroleum Institute Specification 5CT. API 5CT H40 Casing is a reliable, general-purpose casing grade widely used in shallow to medium-depth oil and gas wells.
Brief:API 5L X60 PSL1 Line Pipe is a high-strength steel pipe manufactured in accordance with the American Petroleum Institute (API) 5L specification, specifically designed for the transportation of oil, natural gas, and water in pipeline systems.
Available in various manufacturing processes including seamless (SMLS), high-frequency welded (ERW/HFW), and submerged arc welded (LSAW/SSAW), API 5L X60 PSL1 pipes can be produced in a wide range of dimensions—typically from 21.3 mm to over 2000 mm in outer diameter, with wall thickness customized to meet specific pressure and diameter requirements.
