Our Products
Our Complete range of products are Stainless Steel Socket Weld Flanges, Stainless Steel Spectacle Flange, Stainless Steel Weld Neck Flange, Carbon Steel Flanges and Stainless Steel Long Neck Flanges.
Socket weld flanges is similar to slip on flange in Outline, but the bore is counter bore to accept the pipes. Socket weld flanges are typically used for a smaller size of high pressure pipes. Socket weld flanges are widely used in high pressure system such as hydraulic equipment and streamlines. Socket weld pipe flanges are attached by inserting the pipe in to the socket end and then by applying fillet weld around the hub of the flanges. This allows the smooth bore and travel of the fluid and gases within the system.

Stainless Steel Spectacle Flange.
A spectacle blind or spec blind, is a safety device used to isolate a section of line or piece of equipment when the line or equipment needs to be inspected or removed from service. It is different than a valve in that the blind is a permanent or long term isolation device.
A spectacle blind is machined from a single piece of metal that is cut to match the pipe size, fit between two pipe flanges and requires an additional gasket when it is installed. Also, the bolts will need to be lengthened depending on what piping class and size blind is used. The thickness of the spectacle blind is specified based on the line pressure and pipe size.
TYPES OF SPECTACLE BLINDS
RING SPACER
Ring spacers are bored to the matching pipe ID and are the same thickness as the single blind that it replaces. When removing a single blind, either the flange or associated piping must be pulled together to seal the line, or a ring spacer must be installed to fill the gap. Thick single blinds or rigid piping systems normally require ring spacers.
SINGLE/ LINE BLIND OR BLANK
A positive shut-off device normally installed adjacent to, or in conjunction with, a valve. Their purpose is to prevent accidental flow through a pipeline to a vessel. With the exception of cast iron, plastic, or fiberglass services, they are not drilled with bolt holes, but fit inside the bolt circle of mating flanges. Pipeline blinds or blanks are not the same as bolting blind flanges. Single blinds use standard gaskets.
A combination of a single blind and a ring spacer can be fabricated for field convenience as a single unit. Weight consideration and the associated difficulty of handling heavy pieces in the field are a primary consideration in specifying a spectacle blind or a combination of blinds. Spectacle blinds are meant to be rotated to change blind/spacer orientation.
SPECTACLE BLIND
A spec blind is a combination of a ring spacer and single blind. They are usually permanently installed in a piping system and rotated as needed.
VAPOR BLIND
Similar to a single blind, but thinner, normally 1/8 (3mm) to 5/16 (8mm) thick. These are positive sealing devices intended to prevent accidental flow or leakage of vapors into a pipeline or vessel, usually while the system is in service. Vapor blinds are not to be subject to differential pressure.
TEST BLANK
A test blank is specially designed blank used for hydrostatic or other incompressible fluid testing purposes only. Their advantage is cost and weight savings since higher allowable stress values (or lower safety factors) are used in their design.
Weld neck pipe flanges are connected to the pipe by welding the pipe to the flange. Weld neck pipe flanges are generally used in high pressure applications. The inside diameter of the flange is machined to match the outside diameter of the pipe for the tight hold connection.

Type of Flanges
Stainless Steel Orifice flanges are for metering the volumetric flow rate of liquids and gasses through a pipe. Two orifice flanges are called an orifice flange union. Each flange comes with two pipe taps for measuring the pressure drop of the flow through an orifice plate. Orifice plates do not come with the flanges and are sized based on the requirements of the process. Two jack screws are used to spread the flanges apart in order to change the orifice plate. This flange is normally available in weld neck, slip-on, and threaded flanges. These flanges have a raised face.
Orifice flanges are installed in a straight run of pipe in order to avoid turbulence at the plate. As a rule of thumb, an orifice flange has ten diameters of straight pipe upstream and five diameters of pipe downstream. There are guidelines set out in (American Gas Association) AGA Report #3 which is the Orifice Metering of Natural gas.
When installing the orifice plate flange the pressure taps need to be at the same elevation to each other. The assumption when making the calculation for the orifice plate is that static head of the tubes is the same on both sides of the orifice plate. Pressure taps should not be installed facing down as the taps could become plugged with debris in the line.
Stainless Steel Weld neck orifice flanges are butt-welded into the pipeline. The inside diameter (bore diameter) of the pipe should be specified when ordering. Weld neck orifice flanges are available in standard pressure ratings: ANSI classes 300, 600, 900, 1500 and 2500. They arenotavailable in ANSI 150 sizes because the thickness of ANSI 150 flanges are not enough to allow for drilling pressure taps.
Specialized Blind steel flanges are manufactured of stainless steel which are commonly referred as blanking flanges. Blind flanges are widely used in high pressure application. Blind flanges are generally used for sealing the end of the piping systems to prevent the flow of liquid or gases. The use of Blind flange gives the ease in solution to the sealing of the piping systems.
