2. PRESSURE-TEMPIRATIJRE RATlNS
2.1 Pressure-temperature ratings for these fillings are shown in Table I. Ratings are independent of the contained fluid and are the maximum allowable working pressures at the tabulated temperatures. Intermediate ratings may be obtained by linear interpolation between the temperatures shown.
2.2 The temperatures shown for the corresponding pressure rating shall be the material temperature of the pressure retaining structure. It is implied that the material temperature is the same as the fluid temperature. Use of a pressure rating at a material temperature other than that of the contained fluid is the responsibility of the user and subject to the requirements of any applicable code.
2.3 For purposes of this Standard Practice, castings are included for Class 150 fittings only.
a) The manufacturer’s name or trademark
h) Material identification
c) The symbol “SPI 14” to denote compliance with this Standard Practice
d) (‘lass 1000 or IM
e) Size
f Other markings in accordance with MSS SP.
25. Where size and shape of fittings do not permit all of the above markings, they may be omitted in the reverse order given.
g) The marking of plugs, bushings, and locknuts is not required by this Standard Practice.
5. NIATIRJAI.
5.1 Class 150 fittings shall be cast or may be wrought. (‘lass 10(N) fillings shall be wrought only.
5.2 Castings The chemical and mechanical properties of the castings shall be at least equal to the grades contained in ASTM A 351. Castings shall be heat treated by the solution annealing method specified in ASTM A 351. The castings shall be capable of passing the intcrgranular corrosion tests performed in accordance with practice B of ASTM A 262 with a corrosion rate established between the manufacturer and purchaser. Alternatively, the castings shall be capable of passing the intergranular tests perfonned in accordance with practice E, alternate method B, of ASTM A 262. The manufacturer shall be prepared to certify that the product has been so produced.
5.3 Wrought Fittings, couplings, and caps shall be made from wrought forgings. seamless tubing. or bar stock. The chemical and mechanical properties shall be as a minimum equal to the grades contained in ASTM A 182, A 479 or A 511. Wrought material shall be heat treated by the solution method as specified in ASTM A 182, A 479, or A 511. The wrought material shall be capable of passing the intergranular corrosion tests perfbrmed in accordance with practice E of ASTM A 262. The manufacturer shall be prepared to certify that the product has been so produced.
