Qingdao Lacy Planning Rubber Industry Cluster

On December 5th, 2016, Qingdao Laixi Rubber Materials Industry Cluster District of Shandong Province was planning to enter the first stage of public comment period.

The industrial cluster is positioned as an important rubber material base in northern Qingdao and a pillar industrial base in Laixi.

According to the publicity announcement issued by the website of the Qingdao Municipal Environmental Protection Bureau, the scope of this plan includes: the Western Region covers an area of ​​2.7 square kilometers; the eastern area covers an area of ​​approximately 1.7 square kilometers.

The industrial base will create a space model of "multiple nodes in two areas", that is, in the production and R&D area of ​​two rubber materials, a number of rubber material production and public matching nodes will be laid out.

It is understood that rubber chemical industry is one of Lacey's pillar industries, with a good industrial foundation and a relatively complete industrial chain.

After years of development, this rubber material industrial agglomeration area has become a high-tech industrial agglomeration area integrating tire processing and new material research and development.

In order to better promote the development of the rubber material industry and help Lacey’s economic development, Qingdao City has made special plans for the industrial area.

Pressure seal bonnet is suggested for better closure in high pressure condition, while bolted bonnet is still available for customer's option. 


The pressure seal design incorporates a metal-to-metal seal that becomes tighter as the pressure increases. The initial preload deforms the taper on the soft iron gasket to mate with the taper on the bonnet. The thin knife-edge on the gasket is wedged tightly between the body and the bonnet. The shallow angle insures that the gasket is sealed tightly with only a small upward force on the bonnet. Once the initial seal is created, the body/bonnet joint will remain leak free regardless of thermal or pressure conditions in the valve.After the joint has been assembled, there is no further need to adjust bonnet cap screws.
