A358 / A358M High Temperature Inconel Welded Steel Tube , Electric Fusion Welded Steel Pipe

ASTM A358/A358M

Electric-Fusion-Welded Austenitic Chromium-Nickel
Stainless Steel Pipe for High-Temperature Service

Grade:

316L, 317, 317L, 321, 321H, 348,S32050, N08800.

Welding:

The joints are full penetration bouble-welded or single-welded

Heat treatment:

All pipes are with heat treatment condition.

Please specify your heat treatment requirement in the enquiry.

Permissible Variations—The dimensions at any point in a length of pipe shall not exceed the following:

Outside Diameter—Based on circumferential measurement, 60.5 % of the specified outside diameter.

Out-of-Roundness—Difference between major and minor outside diameters, 1 %.

Alignment—Using a 10-ft [3-m] straightedge placed so that both ends are in contact with the pipe, 1⁄8 in. [3 mm] deviation from contact with the pipe.

Thickness—The minimum wall thickness at any point in the pipe shall not be more than 0.01 in. [0.3 mm] under the nominal thickness.

Table 1 Annealing Requirements

A New designation established in accordance with Practice E527 and SAE J1086.

B Minimum, unless otherwise stated.

C Quenched in water or rapidly cooled by other means, at a rate sufficient to prevent reprecipitation of carbides, as demonstrable by the capability of passing Practices

A262, Practice E. The manufacturer is not required to run the test unless it is specified on the purchase order (see Supplementary Requirement S7). Note that Practices

A262 requires the test to be performed on sensitized specimens in the low-carbon and stabilized types and on specimens representative of the as-shipped condition for

other types. In the case of low-carbon types containing 3 % or more molybdenum, the applicability of the sensitizing treatment prior to testing shall be a matter for

negotiation between the seller and the purchaser.

D Quenched in water or rapidly cooled by other means.

Inspection and Quality Control:

In house control, also accept Customer Inspection at site or Third Party Inspection
