What are the qualities of single-arch rubber expansion joints?
Nov-22-19
Single arch rubber expansion joint for the connection between the pipeline its structure is divided into the inner and outer layer, the middle layer and the outer layer, the inner layer for the nylon cord fabric skeleton layer, which plays a certain qualitative pressure-bearing role, to withstand the high pressure in the pipeline to prevent the bendable rubber expansion joint is torn; outer layer is generally neoprene, mainly for the rubber expansion joint anti-aging and weather resistance.Because the outer layer is neoprene rubber so heat resistance and nitrile rubber equivalent, decomposition temperature 230 ~ 260 ℃, short-term resistance of 120 ~ 150 ℃, in 80 ~ 100 ℃ can be used for a long time, with a certain degree of flame retardancy.
Rubber expansion joint has excellent shock absorption and noise reduction, compressive strength tensile properties, rubber soft connection has the advantages of reducing pipeline noise, good sealing performance, light weight, easy assembly and maintenance, long service life, etc. Both ends of the alignment saturation of the applicable range will reduce 207. in addition, long-term sexual touching noise is very easy to produce eye fatigue, eye pain, eye vision loss, tears, etc.. However, avoid contact with sharp metal instruments to avoid puncturing the sphere.
Installation can produce transverse, axial, angular displacement, not subject to the restrictions of the pipeline is not central, the flange is not parallel.
The range of use is very wide, because it has high temperature resistance, oil resistance, pressure resistance, vacuum resistance, acid and alkali resistance, anti-corrosion, resistance to a variety of chemicals and other types, in the automotive, shipbuilding, chemical, petroleum, steel, printing and dyeing, machinery, instruments and other industrial fields are involved.
Single-arch rubber expansion joints have adjustable characteristics, single-arch rubber expansion joints have approximately equal percentage flow characteristics and adjustable ratios of up to 300:1, so single-arch rubber expansion joints can provide control in a wide range of changes.
