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 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.

S-Stamp und U-Stamp

SELO License - in short

The demand for pressure devices within the Chinese market is steadily increasing. All manufacturers wishing to enter this ever-growing market need a SELO License.

Boilers

The scope includes stationary pressurized hot water boilers, steam boilers and boilers heated with regenerative fuels.

Pressure Vessels

The scope includes stationary pressure vessels which are divided into different licensing categories depending on pressure, volume and medium.

Safety Equipment

The scope of application includes safety equipment necessary for the safe operation of pressure vessels and boilers.

TSG vs. PED/TPED

Opposed to the applicable TSG Regulations, the scopes of the European Pressure Equipment Directives (PED and TPED) are clearly defined.

Standards

Different TSG-regulations may apply to your pressure vessels, boilers and safety equipment. But what exactly are the TSG-regulations?

3rd Party

As of today, third parties are not admitted. This means that only Chinese authorities may perform audits and grant or issue licenses.

Organisation

What many do not know is that numerous other Chinese authorities are also involved in the licensing process.

History

The safety of pressure equipment has always been considered as a national obligation. Over the years, two standard systems have been established worldwide - Where does the SELO license fit in?
