橡胶接头是用于金属管道之间起挠性连接作用的中空橡胶制品。 Introduction: Rubber joints are hollow rubber products used for flexible connection between metal pipes. It consists of inner and outer layers of rubber, ply and traveller, which form a tubular rubber piece. After vulcanization, it is combined with metal flange or parallel joint loose sleeve.

Rubber joints are hollow rubber products used for flexible connection between metal pipes. It consists of inner and outer layers of rubber, ply and traveller, which form a tubular rubber piece. After vulcanization, it is combined with metal flange or parallel joint loose sleeve. Therefore, the flange of the rubber joint is also important. The soft rubber joint can not only reduce vibration and noise, but also compensate for thermal expansion and contraction caused by temperature changes. It is widely used in various piping systems. So how is the flange of the rubber joint anticorrosive?
The flanges of rubber joints can be divided into three types: stainless steel, carbon steel, and cast steel. Among them, carbon steel and cast iron are the most practical. Due to the high cost of stainless steel, stainless steel is not commonly used in practical work unless it is a corrosive medium. The cast steel flange of our Shanghai Luoying Pipeline Equipment Factory is galvanized and spray-coated for anti-corrosion treatment.
The cast steel galvanized flange is anti-corrosion treated by spraying plastic, the cast steel galvanized flange soft joint is composed of cast steel flange and rubber ball, and the cast steel flange is anti-corrosion treated by galvanizing. Since cast steel flanges are manufactured using a casting process and have porosity, the appearance of cast steel galvanized flanges has pores. Although treated, the appearance is affected. Under normal circumstances, cast steel flanges are mostly spray-coated for anti-corrosion treatment. In this way, the pores generated by the casting process are covered with plastic powder, and the appearance of pores is almost invisible. In this way, the appearance of the cast steel spray flange rubber joint is better. After the flange air hole treatment of the cast steel galvanized flange rubber joint, you will see a light orange substance, which generally exists in the hole. Although it affects the appearance, it does not affect the use.
In the process of using rubber joints for the corrosion protection of flanges, paint anticorrosion can also be used. Anticorrosive coatings are generally divided into conventional anticorrosive coatings and heavy anticorrosive coatings, which are an essential coating in paint coatings. Conventional anticorrosive coatings are used to prevent corrosion of metals and other materials under general conditions, and to protect the life of non-ferrous metals. Heavy anticorrosive coatings refer to conventional anticorrosive coatings, which can be used in relatively harsh corrosion environments and have the ability to A type of anticorrosive coating that achieves a longer protection period than conventional anticorrosive coatings.
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 have unique experience and solutions to ensure the quality of each rubber joint. However, Shanghai Luoying Pipeline Equipment Co., Ltd. has been a professional manufacturer of rubber joints for many years. Our company can process rubber. The types are also diverse, and the quality of our Shanghai Luoying products conforms to national standards. The rubber joint products sold are accompanied by a supply list and quality inspection report and a company quality inspection chapter.
