[DIN] Pipeline Expansion Joint “good compression resistance”

Shanghai Songjiang Group Introduce to you: [DIN] Pipeline Expansion Joint “good compression resistance” information. Which is composed of natural rubber and polyester cord fabric, has good compression resistance.

Introduction of [DIN] Pipeline Expansion Joint

DIN Pipeline Expansion Joint（German standard） is composed of natural rubber and polyester cord fabric. The two have complementary advantages in performance. Natural rubber has good elastic and elastic properties, which can provide sufficient and effective compensation for the displacement of the pipeline due to various environmental influences during operation. In addition, polyester cord fabric, as a material with high strength and compression resistance, can effectively improve the compression resistance of the product as the main material of the Pipeline Expansion Joint, and avoid the explosion of the sphere during operation due to excessive pressure. It is mainly used for parts between pipes and valves, between pipes and pipes, and between pipes and equipment, which are connected to each other and play a sealing role, because there are many applications between these equipment and pipes.

[DIN] Pipeline Expansion Joint Features

DIN Pipeline Expansion Joint（German standard） is composed of colloid and two looper flanges. The colloid is made of inner and outer layers of synthetic rubber, skeleton nylon cord, pressurized steel ring, and is made of advanced air blow molding process through high temperature vulcanization. The pipeline rubber bellow produced in this way can make the working pressure of the joints 5 times higher than that of ordinary rubber joints. Especially in the pipeline with corrosion resistance, acid and alkali resistance, and oil resistance, it can show its special effect and improve the service life of the rubber joint.
