High pressure Seamless pipe


ASTM A519 pipe are identified as high-pressure pipe used to transfer oil at high temperatures. API 5L X52, X60, X65 are also referred to as high-pressure seamless pipe. ASTM A335 specification pipe are chrome moly pipe used for high-pressure service application. These pipe are forged, cut to length, bar stock machined, bored from forged pipe with eccentricity not ore than 8%. High pressure is sustained by controlled and consistent grain structure. High pressure pipe are Hot finished with homogenous and consistent tensile requirement. Specific requirements include high yield strength and high tensile strength .The pressure friction resistance is achieved by smoother inner diameter. The inner diameter of these pipe should be free from laps, flaws and fissures deeper than 0.1 mm, max. 5 defects > 0.05 mm per cross-section.

High pressure seamless steel pipe are certified as PER DIN 50049 3.1, EN 10204 3.1/3.2 and NACE MR-0175 & NACE MR-0103

2- – 6- Outer Diameter & 50NB – 150NB Nominal Bore Wall Thickness SCH 120-SCH XXS. High-pressure seamless pipe are supplied in single random length and double random length of 4-7 meters and 7-13 meters respectively.
