Safety Equipment

The scope of application includes safety equipment necessary for the safe operation of pressure vessels and boilers. These include safety valves, bursting discs, safety locks, and pressure-gauges etc.

As TSG-regulations don’t always clearly state if a license is required (see standards) it is extremely difficult for a manufacturer to make regulatory decisions: whilst national standards apply to pressure vessels, they generally don’t apply to safety equipment!

As a result specific type testing is required (see type testing). Such type testing is performed exclusively according to Chinese standards. Occasionally you may not find a Chinese standard specifically applicable to your equipment.

We have experienced this for many years and know how to encounter such situations.

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.

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.

We know your world won't wait.
