Discussion on Issues in the Implementation of the New Version of GB150
Thread Content
As of February 1, 2025, the new version of GB/T150 has come into effect. Any questions or issues that arise during its implementation can be shared for discussion and mutual learning*
Do anyone have any specific questions or difficulties regarding the implementation of the new version of GB/T150? We can specify it, and together we will explore solutions. .

Clause 8.5 of the revised GB150 states that: \"The performance-improving heat treatment carried out by the manufacturer of pressure vessels or pressure components shall be supported by process tests, and the heat treatment process shall be formulated based on those tests.\" Can this be understood as requiring process tests to be conducted before manufacturing, heat treatment to be carried out in the same furnace during manufacturing, and all performance tests to yield satisfactory results? For this requirement, both of these production methods are acceptable. How do everyone understand this requirement?
Your understanding is correct. According to Clause 85 of GB150, heat treatment aimed at improving performance does indeed require support from process testing, primarily to verify whether the selected heat treatment process can meet the anticipated technical requirements and performance standards. Conducting process tests before production is primarily aimed at determining the most suitable heat treatment parameters and procedures, to ensure that the quality of the final product meets standard requirements. At the same time, heat treatment in the same furnace during the manufacturing process, along with various performance tests, is also feasible, as long as the consistency and reliability of each batch of products can be ensured. In practice, an appropriate solution can be selected based on the specific production conditions and equipment capabilities. The most important thing is to ensure that the heat treatment process enables pressure vessels or pressure components to meet the design and usage standards, thereby ensuring safety and functionality. .
In GB/T150: 5.1.5 The classification of vessels is determined in accordance with TSG21, based on the medium group, volume, and design pressure. The classification of medium hazards is carried out in accordance with GB/T42594. Should it be TSG21-2016 or HG20660-2000? How do you all handle it?
Those regulated by TSG21 follow HG20660-2000; those not regulated follow GB/T42594
Are there any official channels for getting formal responses to questions regarding the new standards? The website of the Pot Capacity Standards Committee doesn’t provide any means for feedback, and the experts who conduct standard-related training also don’t answer questions. It takes ten years to develop such standards, but it seems there are many issues with them!
