Bolted rubber soft joint
ball is composed of a rubber tube with an inner rubber layer, a reinforced layer with multiple scraped nylon cord fabrics, and an outer rubber layer. The rubber materials used are different according to different media, including natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene rubber, silicone rubber, fluorine rubber and so on. With heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, oil resistance and other functions. With the substantial increase in the worldwide sales of bolted rubber soft joints, this type of pipe compensation fittings has gradually become an indispensable part of modern industrial pipe laying. Therefore, his installation problems also become very important. Today we will make a detailed summary of the reasons for the cracking of the bolted rubber soft joint.
The strength of the bolted connection is relatively low. If the bonding method is not accurate, the strength of the joint will be lower and cracks may occur. This requires that the vulcanization process of the soft rubberized joint with bolts be controlled during the production process. To avoid insufficient vulcanization.
In the process of using the bolted rubber soft joint, the connection length is not enough, forcibly exceeding the connection length, and the shrinkage range may be cracked. The compensation expansion and contraction of the pipeline must be accurate. According to the pipeline material, temperature, tube length, and expansion coefficient, Accurate amount of expansion and contraction to avoid exceeding the expected compensation amount, resulting in the pull-out of the bolted rubber soft joint.
In some high-pressure pipelines or the bends of pipelines, a limit device must be installed outside the bolted rubber soft joints, especially the bends of the pipes should also be added with brackets or piers to protect the bolted rubber soft joints. .
Fourth, the bolted rubber soft joint may crack under the influence of outdoor weather, exposure to sunlight, etc., below the operating temperature. Outdoor use of bolted rubber soft joints should do a good job of sun protection of bolted rubber soft joints to extend its service life.
The bolted rubber soft joint used in the vulcanization process has a poor performance of the rubber machine or has been self-sulfurized, over-polished, and the wire rope rusted. The strength of the joint will be greatly reduced. When in use, it may be easily spread. The phenomenon that the joint part is disconnected.
Due to the good overall performance of the bolted rubber soft joint, it is mainly used for the lifting and transportation of raw water and sewage, the feed water and cooling circulating water of thermal power plants, metallurgy industry, condensate water, pipeline transportation of chemicals in chemical industry, petrochemical industry Cooling, dilution and other flexible connections between long and short distance pipelines. Because rubber has high abrasion resistance, it is also suitable for low temperature transportation of granular and powdery and vapor in all industries.
