Aesteiron Steels is Orifice Flange Manufacturers & Suppliers. Orifice Flange are for metering the volumetric flow rate of liquids & gasses through a pipe. Two orifice flange 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 Flange are installed in a straight run of pipe in order to avoid turbulence at the plate. While installing the Orifice Plate Flange the pressure taps need to be at the same elevation to each other.

Product Details:

We Aesteiron Steels Pvt Ltd, are one of the Leading, manufactures & suppliers of Slip On Flanges.

Slip On Flanges are a popular type of pipe flanges. These are type of flanges that slide over the end of piping and then welded in place. These flanges are ideal for lower pressure applications. These are easily fitted and welded into different pipes. Welding reduces fabrication costs of these pipes. These are available in wide variety of sizes and applications.

Material Used: Common materials used are as follows :

• Stainless steel
• Brass
• Steel
• Alloy Steel
• Aluminum
• Plastics
• Titanium
• Monels
• Carbon steel
• Alloy titanium etc.

Slip On Flanges Advantages

• Low cost installation
• Less time needed to spent on ensuring the accuracy of the cut pipe
• They are somewhat easier to align
• The slip-on flanges have low hub because the pipe slips into the flange before welding
• The flange is welded both inside and outside to provide sufficient strength
• They prevent leakage

Slip On Flanges Features 

• One size fits all pipe schedules.
• Fabricators can more easily cut pipe to length for slip-on flanges.
• The smaller thickness of this flange allows for easier alignment of bolting holes.
• They are generally not preferred for high pressure temperature environments.

Spectacle Blind Flange is generally a piece of metal that is cut to fit between two pipe flanges & are usually sandwiched between two gaskets. A spectacle blind flange is often made from two metal disc that are attached to each other by small section of steel. The shape is similar to a pair of glasses or "spectacles" hence the name spectacle blind flange.

Aesteiron Steels is Socket Flange Manufacturers & Suppliers. Socket Flange is typically used on smaller sizes of high pressure pipes. This pipe flanges are attached by inserting the pipe into the socket end & applying fillet weld around the top. And hence this help for smooth bore & better flow of the fluid or gas inside of the pipe.

Product Details:

We Aesteiron Steels Pvt Ltd, are one of the Leading, manufactures & suppliers of Socket Weld Flanges.

Socket welding flange, a popular type of pipe flange, was initially developed for use on small-sized high- pressure piping. The fabrication of this type of flange is similar to that of a slip-on flange. However, the internal pocket of a socket weld flange allows for a smooth bore and better fluid flow. When provided with an internal weld, the static strength of this flange is equal to slip-on flange, but the fatigue strength is 50% greater than double welding slip-on flanges. Smooth bore conditions in such a flange can easily be attained without having to bevel the flange face and, after welding, to reface the socket weld flange as would be required with slip-on flanges. For this reason, the internally welded flange is popular in chemical process piping.

Key Features:The recess on the inside diameter of the socket weld flange allows for a good fit of the pipe allowing for a smooth flow of liquid.
Socket welding flanges work well for smaller sizes and higher pressure temperature conditions. They are similar to slip-on flanges, but must specify the schedule of the pipe where they will be used for with socket welds.
