RubberJoint Quality Affect It's Performance


 Rubber joint quality does have great effect on the performance of rubber expansion joint, high-quality rubber joint material is sure to make pipes more long-term stable operation, inferior rubber joint will cause some of the high-pressure pipeline potential hazards occur, resulting in the pipeline project of incalculable loss. So customers must be strict on rubber joint choosing to reduce the project late maintenance. XINLI Pipeline as A professional rubber joint manufacturers, combined with many years of production experience, we'll try to help you distinguish the quality of rubber joint quality.

Firstly for the color of the ball, rubber joint quality of the color sphere is glossy black, and the surface of the sphere rarely appear dirty phenomenon, rubber itself will have a relatively strong pungent taste. It is very obvious. In addition to the glue will cause rubber connector ball color change, product storage for a long time will also caused inner and outer rubber joints appear yellow.
Secondly, pressing rubber joint surface and the observing the hardness of rubber joints, rubber joint has just come out for a period of time, the surface of the sphere with finger pressing can feel a bit soft, this is due to the elasticity of rubber, but the store situation for a long time under the ball in the air in a storm drain will cause it hard, thus seriously affect the displacement compensation performance of the rubber joint.


Rubber Expansion Joint

Rubber expansion joint is widely used in the field of chemical industry, construction, supply water, sewage drainage, petroleum, light and heavy industry, sanitation, plumbing, electricity and other fundamental engineering.

Dismantling Joint

Dismantling Joints are used to connect Flange on the one side and weld pipe on the other,modulate the product's length in between

Duckbill Check Valve

Duckbill check valve is a simple, reliable, cost effective method of backflow prevention. The series flange integral duckbill check valve is designed to be installed between two mating flanges.

Expansion Bellows Compensator

Metal bellows expansion joints (also called Metal Expansion Joint) are compensating elements for thermal expansion and relative movement in pipelines, containers and machines.


Valve is not only own with the functions of opening quickly, easy to maintain, good sealing but also safety fire-safe and Antistatic designs.

Shock Absorber

Shock absorber is adopted in ductile iron, which improves the plasticity and toughness of the product, and the strength of the steel is higher than that of the carbon steel

Pipe Accessory

S312,S404 Water-Proof Sleeve is generally applied to the structure with requirement of vibration or water proof in the position.
