Slip-on Flanges

We provide a large selection of Slip On Flanges to our valued customers, supported by a group of experts. We take great pleasure in creating precise, expertly manufactured slip-on flanges. The pipe is supplied with slip-on flanges, which are then fillet welded. A Slip On Flange's calculated strength under internal pressure is around two-thirds that of Welding Neck Flanges, and its fatigue life is roughly one-third that of the latter. These are flanges that are welded into place after sliding over the end of pipe. To provide the pipe enough strength and stop leaks, the flanges are slipped over it and then welded on the inside and outside.

Slip on rf flanges get their name from the fact that the gasket surface is lifted above the face of the bolting circle. These raised face flanges are easy to detect and are used in a variety of process applications. A slip on blind flange is a blank disk with a bolthole. These blind flanges are used to either terminate or isolate pipe systems. Slip on flange welding involves first slipping pipe flanges over the pipe, followed by fillet welding. In this slip on flange welding procedure, the fitting or pipe is set back from the flange face at a distance equal to the wall thickness (-0" +1/16"). Nishra Overseas is a prominent manufacturer and supplier of slip on flanges in India, with clients all over the world. Whatever your slip on flanges need, we guarantee the greatest quality at the best pricing. Please contact and speak with us.

Properties of Slip-On Flanges

Slip-on flanges have multiple features that make them useful for a variety of industrial applications. Here are the main characteristics of slip-on flanges:
  • Simple installation with little alignment required.
  • Flange connections can be made at a reasonable cost.
  • Versatile and suitable with a variety of pipe materials.
  • Available with various pressure levels.
  • Resistant to thermal expansion and contraction.
  • Ideal for low-pressure systems.
  • Capable of being welded for extra strength.
  • Space-saving design allows for efficient installation.

Slip On Flanges Marking

Every Standards have clearly requirements for steel flanges’ marking style, usually the marking words include seller’s Logo, buyer’s Logo (OEM), standard number, flange’s type, flange’s pressure, flange’s size, flange’s material, place of origin, heat number and other words for convenient to trace. If the flanges repaired by welding, it must mark on flanges showing this flange repared by welding. If the flange’s dimensions (OD, ID, PCD, Thickness, Holes number, Holes diameter, Tolerance etc) are different with the normal standard, it also must mark on flanges where it is different with normal ones. Another important place is heat number marking, it is the tracing base for every piece flange, and from the heat number we can trace to the beginning of raw material import.

  • The Marking Style for European Standards Flanges, DIN, UNI, EN 1092-1 norms etc
