Welded pipe and tubing.

The following restrictions apply to the use of welded pipe and tubing specifications when utilized in piping systems, and not when utilized in heat exchanger, boiler, pressure vessel, or similar components:

(a) Longitudinal joint. Wherever possible, the longitudinal joint of a welded pipe

shall

must not be pierced with holes for branch connections or other purposes.

(b) Class II. Use unlimited except as restricted by maximum temperature or pressure specified in

Table

table 1 to § 56.60-1

(a)

or by the requirements contained in § 56.10-5(b)

of this chapter

.

(c) Class I.

(1) For those specifications in which a filler metal is used, the following applies to the material as furnished prior to any fabrication:

(i) For use in service above 800 °F

.

full welding procedure qualifications by the Coast Guard are required. See part 57 of this subchapter.

(ii) Ultrasonic examination as required by item S-6 in ASTM

A376 (incorporated by reference; see

46 CFR

§ 56.01-2)

shall

must be certified as having been met in all applications except where 100 percent radiography is a requirement of the particular material specification.

(2) For those specifications in which no filler material is used in the welding process, the ultrasonic examination as required by item S-6 in ASTM

A-376 shall

A376 must be certified as having been met for service above 800 °F.
