T/CSHB 0012-2024 Emergency cutoff valve body heat treatment technical specification
Abstract
Main technical content: The valve body of the emergency shut-off valve is a high-precision forging that meets the requirements of valve products and is obtained through a dedicated mold and multi-directional forging technology within the process temperature range. This standard specifies the internal quality, mechanical properties, inspection procedures, and inspection rules of the emergency shut-off valve body after heat treatment. This document is applicable to the microstructure and mechanical property inspection of forged parts made of Q355B material and customer acceptance. The quality inspection and evaluation of forged heat treatment of parts made of other high-strength low-alloy structural steels can also be carried out with reference to this document.
