Product Introduction

Insulated joint is an indispensable and important pipeline accessory in the gas transmission and distribution system and oil pipeline system. It is mainly used in the gas transmission and distribution system and the gas pressure regulating station. Its function is to insulate and isolate the sections of the gas transmission and distribution pipeline, the gas pressure regulating station and the transmission and distribution pipeline from each other, protect it from electrochemical corrosion, extend its service life, and can also be directly buried for use. Based on the comparison, analysis and research with foreign products, the integrated insulation joint of our company is mainly designed for the leakage problems that often occur in China's gas transmission and distribution pipelines.

Product Features and Structural Principles

The integral insulating joint is composed of the following parts: upper and lower pipes, sleeves, insulating parts, seals, and insulating coatings. The upper and lower pipes of the insulating joint are connected with the end pieces, and the insulating parts and sealing parts are clamped to form a double sealing structure with insulating properties. The sleeve adopts two forms of groove welding or direct welding with the upper pipe, which firmly seals the insulating parts and the upper and lower pipes inside to form a "sealed container", which not only ensures good insulation effect, but also greatly improves the pressure bearing capacity of the insulation structure.
