Insulation joints (or isolation couplings or isolation joints) provide electrical isolation and cathodic protection in pipelines, tanks and pump stations where oil, gas and water are the carrier fluids. Insulation fittings are available in sizes ranging from 2 to 48 and pressures ranging from ANSI 150 to ANSI 900.
Three features ensure electrical isolation.
1. insulating gaskets prevent metal-to-metal contact at the joints
2. Internal cavities are filled with a special dielectric compound
3. Inner and outer surfaces are coated with two (2) coats of non-conductive epoxy paint, or according to customer specifications.
The welded end hubs of our insulated joints are supplied according to the customer's pipe specifications. Optional extra-long stubs (supplied by the customer) can be included in the completed joint.
Features of insulating joints:
1. Non-conductive material: The primary feature of an insulating joint is that it is made of a non-conductive material, which prevents the transfer of electrical current.
2. Easy to install: Insulating joints are typically easy to install, as they do not require any special tools or equipment.
3. Wide temperature range: Many insulating joints are designed to withstand a wide range of temperatures, making them suitable for use in a variety of applications.
4. Chemical resistance: Some insulating joints are made of materials that are resistant to chemical corrosion, which makes them suitable for use in chemical processing plants or other environments where chemicals are present.
The primary advantage of an insulating joint is that it provides electrical isolation between two sections of pipe, which can help to prevent electrical accidents and protect personnel.
Insulating joints are commonly used in a variety of applications, including:
1. Chemical processing plants: In chemical processing plants, insulating joints are used to prevent the transfer of electrical current between pipes, which can help to prevent explosions or other accidents.
2. Oil and gas pipelines: Insulating joints are used in oil and gas pipelines to prevent the transfer of electrical current between pipes, which can help to prevent fires or other accidents.
3. Power plants: Insulating joints are used in power plants to prevent the transfer of electrical current between pipes, which can help to prevent electrical accidents and protect personnel.
4. Water treatment plants: Insulating joints are used in water treatment plants to prevent the transfer of electrical current between pipes, which can help to prevent electrical accidents and protect personnel.

1, Product Information: ZHW expansion bellows could primarily reduce the vibration and the noise of the piping system. Completely solve the different piping problems as displacement of joint, axial flex and etc. According to different material requirement, stainless steel bellows could be made as acid proof, alkali proof, and corrosion proof to suit different medium and environment. The material is good sealing, light weighting, easy to fix and maintain, also has long working expecting. But please keep the rubber joint far away from sharp metal in order to avoid breaking of the rubber body. 2, Product Description: ZHWs expansion bellows Series EBF521 can withstand extreme variations in temperature ranging from very low to high temperatures i.e. from Cryogenic up to 600 °C. Stainless steel bellows are diffusion tight, have an excellent chemical resistance as well as high physical strength. On top of it, stainless steel bellows have very good corrosion characteristics. United Flexible bellows and expansion joints are generally produced and assembled in sizes from nominal 40 mm (1-1/2?�) up to nominal 2000 mm (80?�). 3, Product Applications: Absorbs and isolates troublesome pipeline vibrations Smooths out force-pump system pulsations Tranquillize jittering compressor pipelines Also absorbs pipeline expansion, compensates for misalignment, eliminates piping stresses. Ends costly failure and downtime caused by pipeline vibration transmissions Customized to solve your vibration problem 4, Product Features: Reasonable structure, good elasticity, large range of compensation pipeline and little counterforce to the brackets of pipeline. Shock absorption and noise decrease, heat and dust insulation, environmental protection and simple structure bracket. The displacement can be deflected to prevent damage caused by subsidence of connected brackets and equipment base. It can adapt itself to the centrifugal difference of pipeline installation to provide convenience to installation and maintenance. Good resistance to milling, heat, aging and corrosiveness and long service life. Little resistance and little weight. Each performance is better than the compensation device of other materials. The temperature range of media is wide:-40--300°c.
