310 Stainless Steel Stainless Steel Welded Tube Polished Stainless Steel Tubing Stainless Steel Flexible Tube

Plate welded and seamless pipe per ASTM A-358
Introduction and scope	This electrically fusion welded austenitic-nickel stainless steel tubing jacket is suitable for corrosive or high temperature service, both. This specification covers five classes of pipe: Class 1: Double-sided welded with filler material and 100% radiographic. Class 2: Double-sided welding with filler material. X-ray is not required. Class 3: Single-sided welding with filler material and 100% radiographic. Class 4: As Class 3, the Expert Root Pass can be performed without filling. Class 5: Double-sided welding with filler material and spot radiography.
Materials	This specification covers 19 classes of steel materials. The plate meets the requirements of ASTM a-240. The most common fabrication grades are 304, 304 L, 304 H, 316, 316 L, and 310.
Size range	Outside Diameter: 8&"NB (219.08mm) to 36 GG" NB (914, 04 mm) Thickness: NB dimensions in tables 5, 10, 10, 40 and 40 Length: according to customer specifications.
Fabrication process	These tubes are made of horizontal plates that have beveled edges and are gradually formed into a&"or GG" shape. in the hydraulic press Tube edges can be hand TIG welded or continuously on the track and arm Welds will be radiographed as required Pipe annealing is carried out in a continuous furnace Additional straightening, sizing , final finish, pressure test, pickled and passivated, marked and packed.
Tolerances	Outside Diameter: 0.5% of specified diameter based on circumferential measurements. Thickness: the minimum thickness at any point of the nominal thickness shall not exceed 0.3 mm. Roundness: difference between the maximum outside diameter and the minimum outside diameter% Straightness: 3m 3mm. Length: according to customer specifications.
Proof	Side bending weld test. Transverse tensile test in accordance with ASME Code IX, section Qw 150. Hydraulic test ASTM a - 530. Class 1, 3, and 4 radiographs in accordance with ASME Code VIII, point UW 51, ASME level 5. Seconds VIII, para. UW 52.
Marked	All pipes are marked as follows: Volcanic, ASTM a - 358, grade, size, table number, furnace number.
