Welcome everyone to come and buy

Compensation function: Under the same external dimensions, the compensation function of non-metallic rubber joints is much greater than that of metal joints. Especially for the compensation function of lateral displacement, the compensation function of non-metallic rubber joints is almost an order of magnitude greater than that of metal joints.

Compensation resistance: Rubber joints are like an elastomer, which will generate resistance after being shrunk or stretched. The resistance of metal joints is much greater than that of non-metals. This resistance is too great, which is not good for the system and will damage the surrounding equipment.
High temperature and corrosion resistance: The material of the rubber joint not only has good high temperature resistance, but also has excellent acid and alkali resistance. The yield limit of ordinary carbon structural steel is equal to zero under the environment of 600 ℃, and it will oxidize and peel when the temperature is higher. Carbon steel rubber joints are easy to crack during work. Stainless steel rubber joints will have low leakage corrosion in low temperature environments, and their cost is considerable.
Thermal insulation and energy saving performance: The mechanism of the rubber joint itself has thermal insulation performance. However, metal joints do not have this condition. In order to maintain heat, the outer layer of the metal joint is covered with a layer of heat insulation.
Maintenance and replacement performance: Rubber joints need no maintenance during the normal service life; replacement of rubber joints is much more convenient than metal joints. This is especially noticeable for large joints. Because the metal joint must be hoisted as a whole after the ground assembly, large lifting equipment must be used, and the rubber joint can be disassembled and assembled on the system. If it is replaced, its metal structure can be replaced, and the components can be easily wound up.
Service life: The service life of the joint is closely related to the environmental conditions. In coal-fired power plants, the service life is more than five years, and the operating temperature is less than 300 ℃. Not uncommon. The situation for oil-fired power plants is more complicated. If you burn light oil and diesel, the service life of the joint can generally be 3-4 years; if you burn heavy oil or crude oil, because of frequent cleaning, the damage to the joint is very serious, usually only 1-2 years.
Use pressure: rubber joints can be divided into composite joints and rubber joints. The working pressure of composite joints generally does not exceed 0.5 atmospheres (50Kpa); the pressure of rubber joints can reach a dozen atmospheres or even higher.
Use medium: metal joint can be liquid, gas, powder. Rubber joints are generally only suitable for gases. Rubber joints can be either gas or liquid. The operating temperature of rubber joints is generally within 100 ° C.
Shanghai Luoying Pipeline Equipment Co., Ltd. has more than 20 years of production experience. It has strict quality control from the production of rubber joints to finished products. It also uses special rubber to make special rubber joints, regardless of the choice of raw materials. From the manufacturing process of rubber joints, we all have unique experience and solutions to ensure the quality of each rubber joint. Welcome everyone to come and buy!
