TSG vs. ASME

Opposed to the applicable TSG-regulations, the scopes of the applicable ASME codes are clearly defined. This regularly causes unpleasant license audit surprises for US and Canadian manufacturers acting according to ASME codes.

At first glance, the Chinese SELO license seems to be somewhat comparable in structure and preparation with the processes described in the ASME codes. And in fact, there is also a broad agreement on the selection of approved materials. The reasons for this can only be described as speculative! The Chinese authorities only differentiate between pressure equipment requiring a license and license-free pressure equipment (see license mandatory yes/no).

The question as to which is the more conservative: the ASME codes or the TSG-regulations? It can only be answered by saying that the applicable TSG-regulations leave manufacturers significantly less freedom in terms of outsourcing, material selection and manufacturing processes. When a manufacturer inadvertently disregards this, he may well encounter considerably more problems.

We strongly recommend that you involve us from the very beginning- ideally during your initial planning phase. This is the most efficient means of kicking off on the right foot and the only guarantee of encountering less problems whilst saving valuable time and money.
