Heat Treatment Assurance
A full-automatic natural gas furnace with 24 meters in length.The real temperature tolerance could be within 10ºC.
NOTE -It is recommended that the temperature for tempering should
be at least 100°F [50°C] above the intended service temperature; consequently, the purchaser should advise the manufacturer if the service temperature is to be over 1100°F [600°C].
Pipe of Grades P1, P2, and P12, either hot finished or
cold drawn, may be given a final heat treatment at 1200°F[650°C] to 1300°F [705°C] instead of heat treatments specified All pipe of Grades P5c shall be given a final heat treatment in the range from 1325°F [715°C] to 1375°F[745°C].
Quality Ensurance
1.Each lot of raw materials will be tested by spectrometer before put in storage.
2.100%PMI the mother pipe to ensure we put right material.
2.100%PMI the finished pipe again to ensure we produced right grade
Permitted tolerance for OD:
OD | Plus tolerance(+) | Minus tolerance (-) |
10.29-48.3 | 0.4 | 0.4 |
<48.3--≤114.3 | 0.79 | 0.79 |
<114.3-≤219.1 | 1.59 | 0.79 |
