Details Overview
Clamp-type rubber joints are easy to install, low in cost, and convenient to maintain. They reduce vibration, lower noise, have good flexibility, and are easy to use. They have high internal density and good elastic deformation. Clamp-type rubber joints consist of fabric-reinforced rubber components and clamp fasteners, used for pipeline vibration isolation, noise reduction, and displacement compensation. They are a type of pipe joint with high elasticity, high airtightness, media resistance, and weather resistance. ratings: 0.1MPa and 0.6MPa. Applications include connections to pumps and valves, fire-fighting equipment, and pipelines experiencing significant vibration or frequent temperature changes. Suitable media include seawater, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam, and particulate matter. Types include oil-resistant rubber joints, high-temperature resistant rubber joints, acid and alkali resistant rubber joints, wear-resistant rubber joints, seawater resistant rubber joints, corrosion-resistant rubber joints, internally oil-resistant, externally high-temperature resistant rubber joints, and negative pressure resistant rubber joints.
Features: Clamp-type rubber joints reduce vibration, lower noise, have good flexibility, and are easy to use. It features high internal density and excellent elastic deformation.
Clamp-type rubber joints consist of fabric-reinforced rubber components and clamp fasteners, used for pipeline vibration isolation, noise reduction, and displacement compensation. It is a highly elastic, airtight, media-resistant, and weather-resistant pipe joint. This achieves the purpose of compensating for the displacement caused by thermal expansion and contraction of pipelines and water transportation. Compared with ordinary rubber joints, it has the following characteristics:
Clamp-type rubber joints save on flanges and bolts, reducing project costs.
Clamp-type rubber joints do not require flanges at the pipe ends, improving production efficiency.
Clamp-type rubber joints simplify installation and maintenance, improving work efficiency.
The clamps are made of stainless steel, featuring corrosion resistance. Installation lengths can be specified according to standard requirements or designed according to the needs of the connecting customer.

| Note: 1. Special requirements can be made according to user drawings. The sphere can be made of nitrile rubber, EPDM, chloroprene rubber and other materials. 2. For suspended water supply, use products above DN200. The pipeline must have a fixed support or fixed bracket, otherwise the product should be installed with an anti-pull-off device. 3. If the user uses a rubber joint, the corresponding flange should be a valve flange. | ||||||
