품질 냉면 무선 스테인레스 스틸 정밀 파이프 밝은 표면 밀착 관용 ± 0.03mm 공장

냉면 무선 스테인레스 스틸 정밀 파이프 밝은 표면 밀착 관용 ± 0.03mm

Cold drawn seamless precision pipe is manufactured from solid billet through a process of piercing and cold drawing, resulting in no weld line, uniform wall thickness, and excellent dimensional accuracy. Compared to welded tubing, it offers superior pressure resistance and structural integrity, making it ideal for high-reliability applications. Key Features: No weld seam – homogeneous structure Tight tolerance: OD/ID up to ±0.03mm Smooth surface finish: Ra ≤ 0.4μm Enhanced

품질 TP304 /TP 316L 스테인리스 스틸 정밀 파이프 OD 1.6mm - 50.8mm ASTM A269 공장

TP304 /TP 316L 스테인리스 스틸 정밀 파이프 OD 1.6mm - 50.8mm ASTM A269

ASTM A269 precision stainless steel pipe is manufactured to the strict requirements of the ASTM A269 standard, which covers seamless and welded austenitic stainless steel tubing for general corrosion-resistant and high-temperature service. This pipe offers excellent dimensional accuracy, clean internal surfaces, and reliable mechanical properties, making it ideal for instrumentation, medical, and other precision applications. Key Features: Compliant with ASTM A269 standard

ASTM A790 용접된 듀플렉스 스테인리스 스틸 파이프 2205 2507 2304 등급

Welded duplex stainless steel pipe is manufactured by forming a flat strip of duplex stainless steel into a cylindrical shape and welding the longitudinal seam. This process produces a pipe with excellent dimensional accuracy, consistent wall thickness, and a cost-effective solution for corrosive service applications. Our welded duplex pipes are produced using advanced welding techniques including ERW (Electric Resistance Welding), EFW (Electric Fusion Welding), and DSAW

품질 무선 스테인레스 스틸 원형 파이프 ASTM A312 304/304L/316/316L 10S ~ XXS 일계 공장

무선 스테인레스 스틸 원형 파이프 ASTM A312 304/304L/316/316L 10S ~ XXS 일계

Seamless stainless steel round pipe is manufactured without any weld seam, created by extruding a solid billet through a mandrel to form a hollow tube. This process results in a pipe with uniform wall thickness, superior pressure resistance, and excellent structural integrity — making it the preferred choice for high-pressure, high-temperature, and corrosive environments. Unlike welded pipes, seamless pipes have no weak points along the longitudinal seam, offering reliable

품질 ASTM A312 SA312 스테인리스 스틸 무선 파이프 공장

ASTM A312 SA312 스테인리스 스틸 무선 파이프

The ASTM A312 Pipe for Chemical Processing is manufactured in accordance with the internationally recognized ASTM A312 standard, which specifies seamless, straight-seam welded, and heavily cold-worked welded austenitic stainless steel pipes. Designed specifically for high-corrosion and high-temperature service in chemical plants, this pipe offers excellent resistance to a wide range of aggressive media, including acids, alkalis, solvents, and chemical intermediates. Its

품질 해양 화학 용품용 부각성 원형 스테인레스 스틸 파이프 공장

해양 화학 용품용 부각성 원형 스테인레스 스틸 파이프

The High Corrosion Resistance Round Pipe is engineered from premium stainless steel grades with optimized chromium, nickel, and molybdenum content to withstand aggressive environments where standard steel pipes would rapidly degrade. This pipe provides exceptional protection against rust, pitting, crevice corrosion, and stress corrosion cracking caused by chlorides, acids, alkalis, and marine atmospheres. Available in seamless or welded construction, it delivers long-term

정밀 301 304 316 430 냉간 압연 스테인레스 스틸 스트립 2B BA No.4 마감

Precision cold rolled stainless steel strip is a narrow, thin-gauge stainless steel product manufactured to significantly tighter thickness and width tolerances than standard cold-rolled sheet. Unlike standard sheet (typically 1000mm or 1219mm wide), precision strip is produced in narrow widths — usually less than 600mm — and thin gauges from 0.05mm up to 3.0mm. The key differentiator is the tolerance : the precision strip holds thickness variations to as low as ±0.005mm,
