Product Description


Carbon Steel Flanges

Carbon steel flange, that is, the main material is carbon steel flange or end flange connectors. It contains carbon steel flange, known as carbon steel flange.

Carbon Steel Flanges are designed with care using current techniques under the visionary guidance of accomplished professionals at manufacturing unit. Offered range is stringently tested on various parameters of quality for ensuring flawlessness and defect free. These products are widely used in various industries and widely appreciated by clients for owning unmatchable characteristics. Offered range supplied in quality assured packaging material.

Carbon steel flange
ASTM A694

The standards of A694 are more rigorous than the more common SA105N and SA350LF2 grades, providing more robust specifications for high-pressure fluid transmission in oil and gas piping systems. The increased demands on the physical properties of the steel create a stronger metal throughout the pressure range, from low to high temperature services.

ASTM-A694-chemical-composition
ASTM-A694-tensile-requirements

Each grade in the A694 specification is assigned a number correlating to the minimum yield strength (in ksi units) required for that grade; GradeF52 for example requires a minimum Yield Strength of 52 ksi.

SA105N

This is a mild Carbon Steel that is not only one of the most common of the Carbon steels, but also one of the most common steels in the world. It is hard, not brittle or ductile, and has a low price point. SA105N is very common throughout many industries, and is even used with stainless Steel piping systems with the aid oflap joint End Rings

We stock large diameter Fitting(18" – 42") SLIP-ON, Lap Joint, Weld Neck, and Blind Flange in SA105N, in class 150 and 300, and can also source a variety of sizes and classes for longer lead times, from 12" to 60".

SA350 LF2

This is a grade of Carbon Steel intended primarily for low-temperature service and requires notch toughness testing. Very similar to SA105N, this material is used in more industrial applications such as the oil and gas industries.

We can supply large diameter Flanges of all types in SA350LF2, from 18" to 60", in a wide variety of pressure classes.

The A350 LF2 Line is often referred to as Carbon Steel Low Temp Fittings or Flanges

We carry a large inventory of Carbon Steel Flanges in many types and sizes.

Carbon Steel Forged Flanges

A flange is defined as a plate type device, normally round, that is attached to the end of a pipe, fitting, valve or other object to facilitate the assembly and disassembly of a piping system.

Flanges are manufactured in all the different materials to match the material of the pipe and fittings to which they are being attached. While some flanges are made of Cast Iron, the vast majority of flanges are forged carbon steel.

Forged steel flanges are made in seven primary ratings: Class 150, Class 300, Class 400, Class 600, Class 900, Class 1500 & Class 2500-

Chemical Composition of ASTM A694

ASTM A694 Standard covers carbon and alloy steel forgings for pipe flanges, fittings, valves, and parts for high-pressure transmission service.
