insulators are universally applicable in the installation of pipelines  when the carrier pipe runs inside a casing. Plastic insulators provide various advantages:

since the plastic material reduces the friction coefficient to a minimum

– minimised friction prevents damage to the protective coating and insulation of the pipes

all requirements of cathodic protection are met. Plastic insulators are suitable for all pipe diameters from 25 mm upwards and many skid heights are available to suit specific requirements. 

 

 

 

 

Excellent insulating properties of the plastic material ensures all requirement of cathodic protection are met.

GRD series HDPE insulators are suitable for all pipe diameters from 25 mm upwards and many skid heights are available to suit specific requirements. We can also design and produce special specification and typed insulators on customer’s requirements.

GRD Series HDPE insulators are designed and processed under the guidance of the experts from Tsinghua University and Beijing Chemical University Technology, plus the rich experiences provided by the engineers from China Petroleum Pipeline Bureau and foreign products merit as well. The performance of GRD Series HDPE has been approved to reach and above the level of the similar products both from home and abroad. And the integrated cost performance is much above the similar products at home and abroad.　　

We adopt reinforcement measures for GRD  HDPE heavy-duty insulators with steel Straps to fast insulators on the carrier firmly, to insure the quality of the project avoiding the moving or looseness of the insulator in the case of the big-sized pipelines.

6mm thick rubber plate is fixed on the inner wall of the GRD Series insulator so that the external coating of the pipe can not damaged, not only the quality is insured, but also the construction can be speeded up. Furthermore, electric wrench is supplied so that construction is speed up more, and the cost is cut down as well.
