Description

310 Stainless Steel Stainless Steel Welded Tube Polished Stainless Steel Pipe Stainless Steel Flex Pipe

Seamless & Welded Pipe From Plates as per ASTM A-358
Introduction
and Scope

This cover electric - fusion welded austenitic Chromium-nickel stainless steel pipe suitable for corrosive or high temperature service, both. Five classes of pipe are covered under this specification:

Class 1: Double side welded using filler material and 100% radio graphed.
Class 2: Double side welded using filler material. No radiography required.
Class 3: Single side welding using filler material and 100% radio graphed.
Class 4: As class 3, expert root pass may be made without filler.
Class 5: Double side welded using filler material and spot radio graphed.
Materials This specification covers 19 grades of material steel. The plate material comply with the requirements of ASTM A - 240. Most commonly manufactured grades are 304, 304L, 304H, 316, 316L 310.
Size Range OD: 8" NB (219.08 mm) to 36"NB (914.04 mm)
Thickness: NB Size in Schedule 5, 10, 10s, 40, 40s
Length: As per customer specification.
Process Of Manufacture The pipes are manufacutred from levelled plates which are edge bevelled and progessively "O" formed on hydraulic presses. The edges of the pipe are either manually TIG welded or continuously welded on Track and Boom. Weld portion is radiographed as per requirements. Annealing of pipe is carried out on continuous furnace. Pipe is further straightened, sized, end finished, pressure tested, pickled and passivated, marked and packed.
Tolerances OD: +/- 0.5% of specified diameter based on circumferential measurement.

Thickness: Minimum thickness at any point not more than 0.3 mm under nominal Thick.

Out of roundness: Difference between maximum & minimum OD%
Straightness: 3 mm in 3 mtrs.
Length: As per customeer specification.
Test Transverse bend weld tests.
Transverse tension test to ASME code IX para QW 150.
Hydrostatic Test ASTM A-530.
Radiographic classes1,3,4 to ASME Code VIII para UW 51,
Class 5 to ASME.
Sec. VIII para UW 52.
