Plate flanges are typically used in several businesses, where they are primarily used for connecting, and keeping pipes sequester from the outside world in the oil and gas industries. This type of plate flange is one and it can make larger circumference than other flanges and tolerate pressures much higher.

Such advantage is served by in its ability to withstand severe heat and cold while making a lasting cohesion between pipes of different dimensions. The plate flanges are flexible in that they come in different sizes as well as metals composed of carbon steel, stainless steel and alloy steel amongst others.

Plate Flanges Welding

Welding process those have the purpose of connecting the plate flanges to each other or associate dissimilar parts of the system. It’s unquestionable that the tying together of two words is so important! A joint of this sort hardly ever has any risk to leak or break up because the connection is firmly sealed by ordinary methods like nuts and bolts or glue.

Uses of Plate Flange

‘Case heads’ are the plate  flanges that have an impact on both pipes but could be the connection to separate system parts or block defined segments as well.

Plate flanges can be seen at a large variety of applications in the pipe installations. They are favorable in the regularity of connecting metal pipes or toward various the sections of a pipeline’s district.  these purpose these flanges match with 2 metal components to ensure they don’t get united. Their functionality extends over more than metal joints, where they may connect to plastic pipes or even different units of an air conditioning or heating system.

  • Slip-on plates flanges are important when assembling pipes of different diameters since their placement is only done by pushing them into junctions between a pipe and another pipe.
  • Here we will weld the pipes lap joint and butt cut into the metal sheet top. The slip-on plates and the more interesting technique used by lap joints to seal the pipe bodies they join are in sharp contrast. This is the toughest and hardest of steel tests as none can go beyond it.
  • The threaded plates flanges which have the capacity to be run indefinitely and to do the welding under high-pressure, thus, the empowerment of the long-life of threaded plates implies that the threaded plates can be used in both the comparison of industrial life environment.

Types of Plates Flanges Supplier

Types includes slip-on, threaded, lap joint, socket-welding, weld neck, blind, and long weld neck plates. Depending on each specific need and kind of connection certain sources advantages will be applied in different extent.

plate flanges


Platinex Piping Solutions LLP is a specialised manufacturer of high quality ASME/ANSI/DIN standard plate flanges in India. We offer immediate delivery programs for standard size of carbon steel plate flanges and stainless steel plate flanges. Plate flanges can be manufactured as per custom size requirements of our customers.

Stainless steel plate flanges are manufactured from plated produced in accordance to the ASTM A240 and ASME SA240 standards. Plate flanges are widely accepted as an alternative to cast or forged flanges in low pressure applications because of the benefits listed below.

Advantages of Plate Flanges

  • Free of any defects
  • Superior grain structure compared to forged or cast products
  • Extended service life
  • Reduction of the normal maintenance costs

Plate flanges are most widely used in fuel and water pipelines, where two flange plates are bolted together with a gasket in between them. The flange plate will have bolt holes all around the perimeter and will be used to create junctions, tees and joints.

Why Platinex for Plate Flanges Manufacturing

Our Platinex Piping Solutions LLP provide efficient plate flanges used in piping systems for their high performance. Nevertheless, giving an integral level of the advantages possible and the worth of this to your system is enough. Consequently, such fittings should be used in situations where a connection under the ambient pressure exceeding 150 lbs is absolutely vital. On this note, welding robots have an edge in that they are ideal when working with corrosion-resistant materials such as stainless steel and compliance to strict design requirements because of specific code restrictions. Thus, effective performance is obtained when the Platinex plate flanges are installed into your piping system if there is the need for high pressure withstanding and strong resistance against corrosion.
