What are surf flanges?
Sorf flanges are connections used in the oil, gas and petrochemical industries. The term ‘SORF’ stands for Socket Weld and Slip On Raised Face; it refers to a specific type of pipe connection that utilizes socket welding, a low-pressure, leak-free joint between two pieces of pipe or fitting. SORF flanges have raised faces that provide extra strength to withstand higher pressures without leaking. Depending on the application, they are available in different materials like iron, steel, plastic, and other alloys. The dimensions conform to ANSI B16.5 Flange Standards, and they come with raised faces lined with PTFE (polytetrafluoroethylene) ring gaskets for tighter sealing capability when bolts are tightened properly.
Advantages of Soft Flanges
Soft Flanges offer a range of advantages over traditional hard-seated flanges. Soft sealing materials, such as PTFE or polytetrafluoroethylene, give superior sealing qualities to other metals used in the flange connection process. This means greater reliability when the joint is undergoing heavy pressure or vibration and extended life expectancy with reduced maintenance requirements. Moreover, they are lightweight and can easily be installed in tight spaces. They also require less bolting torque to achieve a seal due to their smoother finish which helps save installation time and reduce labor costs. Finally, soft flanges provide enhanced safety since they are designed not to leak even under high pressures or temperatures, unlike metal-to-metal connections.
Types of Soft Flanges
Different types of soft flanges are based on the material used to construct them. The most common type is the rubber flange, made of natural or synthetic rubber. Rubber flanges are used in low-pressure applications and are resistant to many chemicals. Another type of soft flange is the PTFE flange, which is made of polytetrafluoroethylene. PTFE flanges offer high chemical resistance and are ideal for applications involving acids, bases, and other harsh chemicals. Additionally, there are silicone flanges, neoprene flanges, and Viton flanges.
Applications of Soft Flanges
Soft flanges are used in many industrial applications, including petrochemicals, oil and gas, food and beverage, pharmaceuticals, water treatment, etc. They are used in chemical processing plants to transport chemicals from one location to another. Soft flanges transport fluids and gases in production processes in the food and beverage industry. In the water treatment industry, soft flanges transport wastewater and potable water.
Installation of Soft Flanges
Soft flanges are easy to install and involve a few simple steps:
Clean the flange’s mating surface and the piping component’s mating surface.
Apply a lubricant to the gasket to ease installation.
Align the flange with the piping component and insert the bolts.
Tighten the bolts in a crisscross pattern to ensure even gasket compression.
Conclusion:
Soft flanges are an important component in the piping system and offer numerous advantages over their metal counterparts. They are flexible, lightweight, and easy to install, making them an ideal choice for many industrial applications. Different types of soft flanges include rubber flanges, PTFE flanges, silicone flanges, neoprene flanges, and Viton flanges. With the right installation and maintenance, soft flanges can offer a long lifespan and reliable performance in industrial settings.
