Flexible rubber soft joint is also called Rubber Joint, rubber flexible joint, soft joint, shock absorber, pipeline shock absorber, shock absorber throat, etc. It is a kind of high elasticity, high air tightness, medium resistance and weather resistance. The pipe joint is a hollow rubber product that acts as a flexible connection between metal pipes Rubber Expansion Joints,Rubber Flexible Joint,Flanged Rubber Expansion Joint,Flexible Rubber Expansion Joint Inner Mongolia Overseas.Trade co.,LTD , https://www.flangevalvejoint.com
Since Li Yinzhong, the chief engineer of the 10th Anhui Huasu Engineering Project Department, was established in early July, after seeing information on the protection and welding of stainless steel tubes in the network, they actively organized technicians, management personnel, and welding experts to promote nitrogen in stainless steel tubes. The feasibility of the protection welding in this project was scientifically demonstrated. They believed that the Anhui Huasu Engineering Pipeline Welding had a total of 110,000 inch diameters, and the stainless steel welding had a total of 60,000 inch diameters, reaching 55% of the total welding volume, and the pipe material was suitable. The use of Tantalum N2 gas shielded welding will take precedence over traditional argon-filled welding processes, both from welding quality and project cost accounting.
For this purpose, the project department organized all electric welding operators on the site to conduct special training on nitrogen protection welding technology in stainless steel pipes. The technician, Guo Jianwei, who has been working for many years in welding, combined with slides on the technical requirements and precautions for nitrogen protection welding in stainless steel pipes. Explained.
After several days of theoretical training, the welders performed welding practices on the prefabricated site. The pass rate of one inspection was 98%. At present, the tenth-build Anhui Huasu Engineering Project Department is implementing stainless steel pipe welding with nitrogen in a large area.
"Non-gas shielded welding in stainless steel pipe," "Non-swapping" and "Argon gas protection welding" are not much different in terms of technical requirements. Not only are workers acceptable, but welding speed is also guaranteed!" says welder technician Guo Jianwei.
The rubber soft joint products take advantage of the advantages of rubber's elasticity, high air tightness, medium resistance, weather resistance and radiation resistance. High pressure, high temperature mold vulcanization. It has high internal density, can withstand high pressure, and has good elastic deformation effect. Shock absorption, noise reduction, lightweight, non-toxic.
According to the shape, it is divided into: concentric and same diameter, concentric reducer, eccentric reducer.
According to the structure, it is divided into: single sphere, double sphere, elbow sphere.
According to the connection form, it is divided into: flange connection, threaded connection, threaded pipe flange connection.
Flange for connecting rubber joint: DIN BS ANSI JIS standard
Working pressure: 0.6Mpa, 1.0Mpa, 1.6Mpa, 2.5Mpa

The flexible rubber soft joint solves the problem of different diameters when connecting metal pipes, and also has the effect of shock absorption and noise reduction, which can save pipe installation parts and save costs. It has the characteristics of high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration absorption, good noise reduction effect, and convenient installation. It is used in connection with pumps and Valves, pipelines with large vibration, and pipelines with frequent changes in cold and heat.
Rubber soft joint products have high pressure resistance, good elasticity (axial and lateral angular displacement), noise reduction, light weight, shock absorption, easy installation, flexible use, easy replacement and maintenance, and have acid resistance, alkali resistance, oil resistance, etc. Features.
Can be widely used in water supply and drainage, circulating water, HVAC, fire protection, papermaking, pharmaceuticals, petrochemicals, ships, pumps, compressors, fans and other pipeline systems. The ordinary type is used to transport air, compressed air, water, seawater, oil, acid, alkali, etc. at -15℃~120℃. The special type is used to transport the above-mentioned medium or oil, concentrated acid and alkali, and solid materials above -30℃~250℃.
Applicable media: sea water, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam and granular powder.
When using or storing the flexible rubber joint, avoid high temperature, ozone, oil and acid-base environment. A sunshade frame should be built for pipes used outdoors or facing the sun and wind, and it is strictly forbidden to expose to the sun, rain, and wind erosion. The surface of the joint is strictly prohibited to be painted and wrapped with thermal insulation materials. Due to the aging problem of rubber products, it should be checked and replaced in time.
Shijian Company actively promotes nitrogen protection welding process of stainless steel pipe
In July, during the peak construction period of pipeline construction of Anhui Huashi Engineering of Ten Jian Company, in order to improve the welding quality and construction progress, they actively promoted the nitrogen protection welding of stainless steel pipe, and received good results. The qualified rate of one-time welding reached more than 98%. And nitrogen is cheaper than argon, and it is estimated that the entire project can save more than 60,000 yuan in cost.
