At present, the company's main production equipment includes: 68 welding equipment; 21 machines plus equipment; 16 vulcanizing equipment; 8 rubber mixing equipment; 20 hoisting equipment; 3×7 meters curing tank, 5×13 meters curing tank.

Liwei Industry is the rubber joint national standard drafting unit, the main process is molding, specifications from DN25-DN3800, is the most comprehensive mold library in China. The rubber joint is formed by a combination of automation and manual mode, which is fast and can be mass-produced. We can also customize the joint by hand winding process to meet customer needs.

Our rubber joint adopts a streamlined, large deflection design, which does not affect the flow rate during pipeline transportation, and plays the characteristics of shock absorption, noise reduction and multi-directional displacement. At present, there are natural rubber, butyl rubber, neoprene rubber, EPDM rubber, nitrile rubber, etc., to meet the needs of different media.

It is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, water heating, fire protection, electric power and other basic projects. According to different materials can be made into acid, alkali, corrosion, oil, high temperature, radiation, wear resistance, aging and other varieties, to adapt to a variety of media and environment.

Pipe lining rubber can be made of DN25-DN2200 pipe, lined with 2mm- 18mm rubber plate. The products can be lined with pipe liner, tank liner, valve liner and so on. In addition to the conventional valve liner, we can also provide alloy steel, alloy copper, stainless steel and other special materials of the valve liner, which is also our cooperation with Tsinghua University innovation.

Team members have excellent communication skills and efficient working ability, pay attention to cutting-edge technology trends, and constantly introduce innovative and unique new products and solutions; We also actively participate in industry exchanges and forums to learn and accumulate new achievements in related fields.

We focus on team collaboration and communication, and encourage experience sharing and technical exchange among members to improve the overall comprehensive strength of the team. We also implement strict quality management, and each project executes a standardized management process to ensure product quality and the stability of engineering implementation.

Our R & D team always adheres to the spirit of "always on the road, constantly challenging ourselves, advancing with The Times", takes customer satisfaction as the goal, constantly pursues excellence and innovation, and provides customers with more quality and efficient services and solutions.
