Pressure Vessels

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

Transportable pressure vessels and all vessels and equipment designated to the defense, nuclear, aerospace, railway, mining and shipping sectors are excluded from the scope. These are subject to separate and more specific regulatory requirements, verifications and standards!

Identifying and/or excluding equipment not subject to the license requirements isn’t always clear, and even if your equipment doesn’t specifically fall under TSG-regulations, there could quite easily be the need to meet some other regulatory requirements. The interpretation of “transportable” and “stationary” is also not always clearly defined, and it is almost impossible to interpret the regulatory requirements applicable to the scope of the piping.

It is crucially important that you get things right from the very beginning. Failing an audit could well mean going back to start and having to re-invest time, costs and effort. Our experts are familiar with the correct interpretation of rules and regulations and will efficiently guide you through the process.

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.

Safety Equipment

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

Standards

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

TSG vs. PED/TPED

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

3rd Party

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

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?

Organisation

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

TSG vs. ASME

Opposed to the applicable TSG-regulations, the scope of the applicable ASME codes is clearly defined.
