FLANGES MANUFACTURERS & SUPPLIERS
OM Tubes is a flanges manufacturer and flange supplier. These flanges are subject to manufacturing processes using equipment and machinery used by world class mills. Flanges are made in carbon steel, stainless steel and nickel alloys based on customer requirement. OM Tubes adds a plethora of accessories such as fasteners and gaskets along with the flanges. Thus provides the customer with a one stop solution.
FLANGES : PRODUCT
Flanges are connection supports used in a pipeline to connect two major pipelines. The mechanical support provided with flanges provides a steady equipment design for the pipeline. For supporting a greater mass, a heavier flange body is required. The structural strength provided by the flanges is a great value addition required in the pipeline design. Flanges are connected to each other with the use of fasteners and gaskets.

FLANGE FACING
Raised Face
Raised Face is the most applied flange facing type and easy to identify. Gasket surface is raised above the bolting plane. The principle of raised face is to establish more pressure on a smaller gasket area the thereby increase the pressure containment capability of the joint.
As per ANSI/ASME B16.5, flanges designed under pressure class 300 lbs has 1.6mm raised face height and 6.4mm for flanges over 400 lbs and 2500 lbs pressure class.
Ring Type Joint (RTJ)
Ring Type Joint has grooves cut into their faces to accommodate a steel ring gasket between two similar RTJ facing and form a tight seal when the bolt is tighten.
An RTJ Flange may have a raised face with a ring groove, but it does not serve as any part of the sealing assembly. Ring Type Joint flanges are applied for high pressure, high-temperature application with “initial line contact” mechanism served by the metallic ring gaskets.
Flat Face (FF)
Flat Face Flanges have gasket surface in the same plan that of the bolting surface. Mostly flat facing is applied on flanged ends, which are produced from castings or fiber glass.
Flat Face flanges are never to be bolted against a raised face or any other. If required, the raised face should be removed prior to installing. Failing to which will result in damage and shut down of the process.
Male & Female (M&F)
Male & Female Grooved Flanges must be matched. One flange has an area that extends beyond the normal flange face, which is male joint. The other flange or mating flange gas a matching depression or groove machined into its face to crate the locking mechanism.
Male Female Joint Flanges are commonly used for high pressure and high-temperature services, namely Heat Exchanger & Boiler assemblies.
Tongue & Groove (T&G)
Like Male-Female, Tongue & Groove Flanges also must be matched too. One flange has a raised ring called as Tongue machined into the face while the mating flange gas a matching depression or the groove.
Prominently found on flanged pump covers and valve bonnets. Also used for high temperature and high pressure applications. None of the facing should be inter-joined to create any flange joint.
FLANGE FACE FINISH
Stock Finish
Most widely used among any flange face finish and practically suitable for flanges under all ordinary service conditions. Under Bolting compression, the soft face from a gasket will embed into this finish, which helps create a seal and a high level of friction is generated between the mating surfaces.
Concentric Serrated
As the name suggest, concentric serrated finish comprised of concentric grooves. A 90 Deg tool is used and serrations are spaced evenly across the face.
Spiral Serrated
Spiral serrated finish is a continuous or photographic spiral groove but it differs from the stock finish in that the groove typically is generated using a 90-deg tool which creates a “V” geometry with 45 Deg angled serration.
Smooth Finish
Smooth finish shows no visual apparent tool markings. These finishes are typically utilized for gaskets with metal facings such as double jacketed flat steel and corrugated metal. The smooth surfaces mate to create a seal and depend on the flatness of the opposing faces to effect a tight seal. This is typically achieved by having the gasket contact surface formed by a continuous spiral groove.
FLANGE GASKET
Gaskets are important to realize a leak free flange connection. Gaskets are compressible sandwiched material in the form of sheets or rings pressed against the mating surface of the flange faces to create a static seal.
The principle mechanism of the gasket is to occupy the microscopic spaces and irregularities between the flange facing and form a seal that is designed to keep hold on liquids and gases. Gaskets are available in a variety of styles, shapes, sizes, material, etc. ASME B16.20 is designed specifically for Metallic and Semi Metallic Gaskets Pipeline flanges and ASME B16.21 is design specification for Non-Metallic Flat Gasket for Pipeline Flanges.
FLANGE BOLTING
Flange are mated together by use of suitable bolting products. This includes Hex Bolts, Screws, Studs, Nuts, Washers, and Pin, etc. The quantity will vary on size and pressure class of the pipeline flanges. Diameter, length is also dependent on the flange size & pressure class.
Widely used bolts in Process Piping & Oil-Gas Industries for ASME B16.5 Flanges are Stud Bolts. Stud Bolts with 2 nuts and washers as per requirement of bolting friction. ASME B16.5 & ASME B18.2.2 specification states bolting requirement for pipeline flanges with different material standards.
PRODUCTION OF FLANGES
We have world class machinery for flanges manufacturers. We have CNC, Lathe Machines as well as punch dyes required for manufacturing of flanges. The forgings are outsourced. We have in house testing facilities like Spectro machine, PMI Machine, Mechanical test, Hardness Test, Ultrasonic Testing, Hydrostatic Testing, Pressure testing, and manual inspection of gauge. Our product range also includes pipe fittings and fasteners which are considered piping accessories for a pipeline set up.The production Raw material is subject to heat treatment for optimum use of a dye for processes ahead. Then the flanges are made as per dimensions specified in the ANSI Standards with a hub or without the addition of the hub. Then the flanges are machined and finished and then the marking process of the flanges is done.
