Oil refinery picks valve locks
March 1st 2008

One of the largest oil-refining projects in China, the Xinjiang Dushanzi Project, is due to have more than 700 Netherlocks valve safety devices installed.

HQCEC, the EDC contractor for the CNPC project, recently bought 718 MRL valve locks from the Dutch company to make sure that high standards of safety will be ensured in the facility.

They are designed to operate reliably at low temperatures and in high-stress environments, such as those found at the Dushanzi site.

The valve interlocks eliminate the potential for human error in processes which involve the operation of manual valves, requiring safe procedure to be followed. The locks physically prevent a user from performing potentially dangerous actions, protecting people and property from damage; until the correct key is inserted, the Multi-Rotation lock will not allow the valve to be operated.

Netherlocks says that, to date, this is the largest number of interlocks provided for such a venture in China, reflecting both the size of the project and the increased focus on safety that is becoming so important in China.
