Pressure Vessel Inspection Code:

Maintenance Inspection, Rating, Repair, and Alteration

1 Scope

1.1 GENERAL APPLICATION

This inspection code covers the maintenance inspection,

repair, alteration, and rerating procedures for pressure vessels

used by the petroleum and chemical process industries. The

application of this inspection code is restricted to organizations

that employ or have access to an authorized inspection

agency as defined in3 .4. Except as providedi n 1.2, the use of

this inspection code is restricted to organizations that employ

or have access to engineering and inspection personnel or

organizations that are technically qualified to maintain,

inspect, repair, alter, or rerate pressure vessels. Pressure vessel

inspectors are to be certified as stated in this inspection

code. Since other codes that cover specificin dustries and general

service applications already exist (for example, Sections

1.2 SPECIFIC APPLICATIONS

1.2.1 All pressure vessels used for Exploration and Production

(E&P) service [for example, drilling, producing, gathering,

transporting, lease processing, and treating liquid

petroleum, natural gas, and associateds alt water (brine)] may

be inspected under the alternative rules set forth in Section 8.

Except for Section6 , all of the sections in this inspectionc ode

are applicable to pressure vessels in E&P service. The alternative

rules in Section 8 are intended for services that may be

regulated under safety, spill, emission, or transportation controls

by the US. Coast Guard; the Office of Hazardous Materials

Transportation of the U.S. Department of Transportation

(DOT) and other units of DOT; the Minerals Management

Service of the U.S. Department of the Interior; state and local

oil and gas agencies; or any other regulatory commission.

'I' and Of the and 1.2.2 The following are excluded from the specific require-

Code and the National Board Inspection Code), the industries ments of this inspection

that fit within the restrictions above have developed this

inspection code to fulfill their own specific requirements.

This inspection code applies to vessels constructed in

accordance with the APYASME Code for Unfired Pressure

Vessels for Petroleum Liquids and Gases, Section VI11 of the

ASME Code, and other recognized pressure vessel codes; to

nonstandard vessels; and to other vessels constructed noncode

or approved as jurisdictional special. This inspection

code is only applicable to vessels that have been placed in

service (including items further described in 1.2) and have

been inspected by an authorized inspection agency or

repaired by a repair organization as definedin 3.15.

Adoption and use of this inspection code does not permit

its usei n conflict with any prevailing regulatorreyq uirements.

a. Pressure vessels on movable structures covered by other

jurisdictional regulations (see Appendix A).

b. All classes of containers listed for exemption from construction

in the scope of Section VIII, Division 1, of the

ASME Code (see Appendix A).

c. Pressure vessels that do not exceed the following volumes

and pressures:

1. Five cubic feet (0.141 cubic meters) in volume and 250

pounds per square inch (1723.1 kilopascals) design pressure.

2. One and a half cubic feet (0.042 cubic meters) in volume

and 600 pounds per square inch (4136.9 hlopascals)

design pressure (see Appendix A).
