Rubber joints are widely used in industrialization, and because rubber joints have good overall performance, they are widely used in chemical plants, construction, water supply and drainage, drainage pipes, crude oil, light and heavy industry, refrigeration, environmental sanitation, plumbing installation, fire safety and stability, electric power engineering and other basic engineering projects. The normal easy-to-use material of rubber joints is 0-60 temperature ℃ general water general water, such as oil, strong acid, strong alkali, continuous high temperature and other corrosion-resistant materials, should choose the corresponding durable material rubber joints, can not be actively mixed or general.
Corrosion-resistant rubber joints, joints applied in the self-priming pump import and export trade, should be located near the self-priming pump side, and self-priming pump in the middle should be assembled metal material size head joints, and assembly can achieve the size head size mouth effect. When the amount of pipeline movement ≥ the maximum compensation amount of the joint, the total number of corrosion-resistant rubber joints should be increased to parallel surface movement, prohibit in order to regulate the deviation of the pipeline, so that the corrosion-resistant rubber joints in the case of disturbing movement and bias, can not exceed the degree (pulling and shrinking, moving, shifting, etc.).
