Heat Treatment Assurance

Our facility features a fully-automatic natural gas furnace measuring 24 meters in length, capable of maintaining temperature tolerance within 10ºC. For optimal performance, we recommend tempering temperatures at least 50°C above intended service temperatures.

Important Note: When service temperatures exceed 600°C, please advise our manufacturing team to ensure proper heat treatment specifications.

Quality Assurance Process

Each raw material lot undergoes spectrometer testing before storage
100% Positive Material Identification (PMI) on mother pipe to verify material composition
100% PMI on finished pipe to confirm correct grade specification

Permitted Outer Diameter Tolerances

Outer Diameter (mm)	Plus Tolerance (+)	Minus Tolerance (-)
