Langfang Wei Bi AI Machinery Co., Ltd., founded in April 2006, is a wholly owned company in Italy.

It is mainly engaged in the design, production and testing of integral insulation joints. The products are used for cathodic protection in pipelines and pressurized systems such as oil, gas, water, hydrocarbons, vapors and corrosive liquids. The insulation joints are made of carbon steel, stainless steel, copper and various alloy steels.

In the past more than 30 years, a large number of field studies have proved that the effect of the integral insulated joint on the corrosion protection of buried pipelines is unparalleled by other anticorrosion methods. The wide application in the world, the well-known engineering design and the extensive use of oil and gas pipelines all prove this point.
