식료품 화학 가공 용으로 용접된 오스텐이틱 스테인레스 스틸 파이프

The Austenitic Stainless Steel Welded Pipe is manufactured from high-quality austenitic stainless steel coils or sheets, formed into a cylindrical shape, and longitudinally welded using advanced Tungsten Inert Gas (TIG) or Laser welding technologies. Austenitic grades are characterized by their face-centered cubic crystal structure, which provides excellent formability, toughness at cryogenic temperatures, and outstanding corrosion resistance. This welded pipe offers a cost

품질 TP316L SMLS 파이프 저탄소 몰리브덴무 로저 무선 파이프 공장

TP316L SMLS 파이프 저탄소 몰리브덴무 로저 무선 파이프

TP316L SMLS pipe is a low carbon, molybdenum-bearing austenitic seamless stainless steel pipe designed for superior corrosion resistance in aggressive environments. The "TP" designation indicates that the pipe meets the requirements of ASTM A312, the standard specification for seamless, welded, and heavily cold worked austenitic stainless steel pipes. "SMLS" denotes seamless construction, meaning no longitudinal weld seam exists. The low carbon content (0.030% maximum)

품질 ASTM A500 스테인리스 스틸 쿼어 파이프 클래스 B 구조적 쿼어 홀 섹션 공장

ASTM A500 스테인리스 스틸 쿼어 파이프 클래스 B 구조적 쿼어 홀 섹션

What Is ASTM A500? ASTM A500 is the American standard for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is the go-to specification for structural applications where strength, weldability, and economy are required. Square steel tubes under ASTM A500 are produced as cold-formed welded tubes, then heat-treated to remove internal stresses and improve mechanical properties. The standard covers four grades: A, B, C, and

크롬 망간스 아우스테니트 무선 파이프 산업용 니켈이 낮은 대안

Chrome-Manganese Austenitic Seamless Pipe with Mill Test Certificate The Chrome-Manganese Austenitic Seamless Pipe is an austenitic chromium-nickel-manganese alloy that provides an economical solution for moderately corrosive environments. Compared to standard carbon steel, it delivers superior oxidation resistance and significantly higher mechanical strength. At ZhongCheng, we manufacture these pipes in strict accordance with ASTM A554 / A312 standards, ensuring precise

품질 산 내성 SS316 꿰매지 않는 파이프 저탄소 황에 대한 우수한 저항성 공장

산 내성 SS316 꿰매지 않는 파이프 저탄소 황에 대한 우수한 저항성

Acid-resistant 316 seamless tube is a premium austenitic stainless steel product specifically designed for service in acidic and chemically aggressive environments. The addition of 2-3% molybdenum distinguishes this grade from standard 304, providing significantly enhanced resistance to a wide range of acids, including sulfuric, phosphoric, acetic, and organic acids, as well as chloride-induced pitting and crevice corrosion. The seamless manufacturing process ensures uniform
