What is the difference between a Stainless Steel 310S flange and a gasket?
A stainless steel 310S flange is a low-carbon version of the 310 grade. These flanges are designed to connect a range of pipes, tubes, valves, and other piping equipment in the system. They provide structural stability to the piping module as it goes through fluctuating pressures and temperatures across the system. Flanges are generally screwed or bolted, making them easy to install and dismantle for repairs or reimbursement. They can also be welded in place if the need arises. A gasket is a component that is fitted between two gaps or sections in pipes when a flange is installed. These gaskets play a pivotal role in sealing the connection between the flange and the piping components. They act as static seals within the line.

How are 310S Stainless Steel pipe flanges made?
310S stainless steel pipe flanges are compact structures that are designed for optimum performance in the piping industry. These Stainless Steel 310S Flanges are manufactured, making use of three techniques, namely casting, cutting the material from a rolled plate, and forging.

  • Casting
    In this method, molten metal is poured into a mold to form the desired shape. After the liquid in the mold is hardened it is removed from the cast and machined to appropriate dimensions and surface finishes.
  • Cutting
    In the cutting process, the metal is cut and flattened using rollers until it reaches the intended thickness. The flange is then cut to meet the appropriate outside and inner diameter of the flange.
  • Forging
    Forging makes use of hot steel billets, which are placed over extruded metal, and hammer pressed or run over dies to form the solid flange shape. After forging takes place, the metal is machined to get it in shape.

ASTM A182 F310S blind flange vs spectacle flange
Blind flanges and spectacle flanges have the same function of isolating sections of equipment and pipeline in the systems. However, they have some features that help in differentiating them.

  • ASTM A182 F310S blind flange is a module that completely isolates the ends of hydraulic systems and curtails the flow. Spectacle flanges are made up of a spacer and a blind cap. These components help in blocking pipe modules providing room for maintenance or the addition of new components in the system.
  • Spectacle flanges are designed with a spacer and a blank end. Blind flanges are components, which possess no head and have a singular end that effectively seals the pipeline.
