Flanges Manufacturer in Bhavnagar


Flange Manufacturer in Bhavnagar

The trustworthy leading flanges Manufacturer in Bhavnagar, with ex stock inventory of 500 tons Flanges are used for connecting pipes, valves, pumps, and other equipment to form a piping system. The use of flange provides easy access for cleaning, inspection, or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. We are specialized in manufacturing a comprehensive range of carbon steel flanges, mild steel flanges, and stainless steel flanges from ½” NB to 48” NB. Steel flanges are widely used as connectors in piping systems to connect pipes to pipes, tees, reducers, elbows, valves, and other piping equipment.

What is a Flanges? What are the Various Types of Flanges?

A flange is a type of fitting used to connect pipes, valves, pumps, and other equipment to form a piping system. A flanged joint involves three separate components; the flanges, the gaskets, and the bolting. One of the most important advantages of using a flange is that it allows more flexibility in maintenance.

The various types of flanges include Weld neck Flanges (WNRF), Slip-on Flanges (SORF), Blind Flanges (BLRF), Lap Joint Flanges, (SOLJ), Socket-weld Flanges (SWRF), Screwed (Threaded) Flanges, Long weld neck Flanges (LWNRF), Spectacle Blind Flanges, Spacer & Blind Flanges, Ring Type Joint Flanges (RTJ), Reducing Flanges, Raised Face (RF) Flanges, Orifice Flanges, Large Diameter Flanges, Custom Flanges, Drawing Flanges, Forged Flanges, Plate Flanges, Flat Face Flanges, etc.

What is flange material?

Materials for Flanges. Pipe flanges are manufactured in all the different materials like stainless steel, cast iron, aluminium, brass, bronze, plastic etc. but the most used material is forged carbon steel and have machined surfaces.

What is flange grade?

The most common materials for pipe flanges (forged grades) are: ASTM A105 (carbon steel high temperature to match A53/A106/API 5L pipes), A350 Grades LF1/2/3 (carbon steel low temperature to match A333 pipes), A694 Grades F42 to F80 (high yield carbon steel to match API 5L pipe grades), ASTM A182 Grades F5 to F91.

What is flange standard?

A flange standard lays down the dimensions, surface finish, facing type, marking, material and technical specifications for flanges. National flange standards in Europe have largely been superseded by the European EN 1092 series.

What are the different flange standards?

Standard Flange Classification: The most common flanges pressure classes are #150, #300, #600, #900, #1500, #2500 and #3000 according to ASME designation. To other standards, as DIN, pressure classes are defined by the acronym PN, as for example, PN10, PN16, PN20, PN25, PN40, PN50, PN100, PN150, PN250 or PN420.

Flanges Classification

Each of the above characteristics will have an influence on how the flange performs across a range of processes and environments.
So how can you tell which flanges are up to the task and which are not?
Flanges are often classified based on their ability to withstand temperatures and pressures.
This is designated using a number and either the “#”, “lb”, or “class” suffix. These suffixes are interchangeable but will differ based on the region or vendor.

Flanges Standards & Markings

To help make comparison easier, flanges fall under global standards established by the American Society of Mechanical Engineers (ASME) — ASME B16.5 & B16.47.
If you’re attempting to replace or verify existing parts, all flanges must include markers — typically on their outer perimeter — to aid in the process.

These markers also follow a strict order:
  • Manufacturer logo or code
  • ASTM material code
  • Material Grade
  • Service rating (Pressure-temperature Class)
  • Size
  • Thickness (Schedule)
  • Heat Number

  • Common classifications include:
  • 150#
  • 300#
  • 600#
  • 900#
  • 1500#
  • 2500#

  • Exact pressure and temperature tolerances will vary by materials used, the flange design, and flange size. The only constant is that in all cases, pressure ratings decrease as temperatures rise.


    Special designations, if any — for example, QT for Quenched and tempered or W for repair by welding This guide offers a solid foundation of the basics of flange design and how to choose the ideal flange for your piping system. However, with a wide range of stainless steel flanges and other flange materials available, it is impossible to list every configuration, detail, or consideration.
