Rubber joints play a vital role in heating pipes.

According to the connection form, rubber joints are divided into three types: loose flange type, fixed flange type and threaded type; according to the structure, they can be divided into five types: single sphere, double sphere, concentric reducer, eccentric reducer, curved sphere and fan coils. Rubber joints are made of inner and outer layers of rubber, cord fabric layer and steel wire ring, which are formed by vulcanization and then loosely combined with metal flange or parallel joint.
 
This product is widely used in various pipeline systems because it can reduce vibration and noise, and compensate for heat rise and cold shrinkage caused by temperature changes. Heating system has many different classification methods, according to the different heat medium can be divided into: water supply heating system, steam heating system, hot water heating system can be divided into natural circulation system and mechanical circulation system. According to the different ways of water supply and return, hot water heating system can be divided into single pipe system and double pipe system.
 
According to the different ways of pipe laying, hot water heating system can be divided into vertical system and horizontal system. According to the different temperature of heat medium, the hot water heating system is divided into low temperature heating system and high temperature heating system.
 
Bendable rubber joint and flange supporting combination of what happens.
 
According to the use of the flange selected for use is not the same, commonly used three kinds of cast steel, stainless steel and cast steel these three, supporting the flange no matter which is slotted flange, now on the market more sales is cast iron flange, the price is cheaper. The disadvantage is that sometimes porous, easy to rust over time, stainless steel flanges supporting rubber joints are mostly used for more demanding pipeline projects, such as chemical pipelines, petroleum natural gas pipelines, etc., the selection of the right counterpart flange is to be given to perfect, durable as well as connection methods.
 
Select pipeline flat welding flange please use the following criteria.
 
1 . Water pipeline mouth its connection part of the inner diameter must be the same as the inner diameter of the rubber anti-vibration joint.
 
2 . The contact surface of the flange connected to the mouth of the water pipe must be smooth and flat in order to ensure a sealing space. If the contact surface of the rubber joint is not tightly bonded with the water pipe, there will be noise, insufficient pressure and water leakage.
