Applicable pressure vessels

This Japanese Industrial Standard applies to the construction and fixtures of pressure vessels with the design pressure of less than 30 MPa.

The pressure vessels refer to vessels which retain pressure or contain fluid generating pressure, or to those which retain external pressure (hereafter referred to as "pressure vessels").

However, pressure vessels given in a) to f) below are excluded.

NOTE: The pressure, unless otherwise specified, means gauge pressure.

a) Those within the scope of other Japanese Industrial Standards 1)

b) Those made of non-metallic materials

c) Those used for atomic energy

d) Those with riveted or soldered structure

e) Those exposed to direct fire

f) Those with special structures 2) or for special applications 3)

Notes 1) Examples are shown below.

Example 1 JIS B 8267 Construction of pressure vessel

Example 2 JIS B 8266 Alternative standard for construction of pressure vessels

Example 3 JIS B 8201 Stationary steel boilers – Construction

Example 4 JIS B 8240 Construction of pressure vessels for refrigeration

Example 5 JIS B 8241 Seamless steel gas cylinders

Example 6 JIS B 8248 Cylindrical layered pressure vessels

Example 7 JIS B 8501 Welded steel tanks for oil storage

2) Such as those with complicated shapes, flat-bottom cylindrical tanks for low temperature and tanks with membrane structure.

3) Pressure sections of rotating or reciprocating machines such as oil or water pressure machines, pumps, compressors, turbines, internal combustion engines, water or pneumatic pressure cylinders.

Scope of pressure vessels

Scope of pressure vessels shall include the main body [shells, end plates and nozzle stubs (nozzles) directly connected to them] and the sections shown in a) to c) below:

a) fixing sections to the piping,

1) to the first circumference joint (excluding the welded joint), for welded joints;

2) to the first screwed joint, for screwed joints;

3) to the first flange surface, for bolted flanged joints;

b) sections to the welded joint, in case the fixtures are welded directly onto the pressured sections;

c) sections to the cover plate subjected to pressure such as manhole and hand hole (including welded joints, bolts and nuts and gaskets).

Valves may be included in the scope of pressure vessels.
