DIN flanges

on

DIN Flanges production and processing of finished solution treatment must be enclosed , so that product performance is optimal.

Applications Of DIN Flanges

In many applications, engineers need to find a way to close off a chamber or cylinder in a very secure fashion, usually because the substance inside must differ from the substance outside in composition or pressure.

  • DIN Flanges used in Chemical and petrochemical processing
  • DIN Flanges used in electronics
  • DIN Flanges used in processing equipment for maintaining product purity in handling foods, synthetic fibers
  • DIN Flanges used in marine and offshore engineering

DIN Flanges Norms

All the Raw Materials received by our company are subject to chemical and physical test and weighed immediately on receipt only thereafter they are taken in the stock.

The Welding neck flanges is normally referred to as the high hub flange.

Welding Neck Flanges

A weld neck flange (also known as a high-hub flange and tapered hub flange) is a type of flange.

Threaded Flanges

Threaded flanges are widely demanded as pipe flanges i.e called as threaded pipe flanges used in different industrial applications.

Slip-on flange

Slip-On flanges or SO flanges are commonly lower in price than weld-neck flanges, and to this effect are a popular choice for our customers.

Blind Flanges

The blind flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes.

Flange facing types according to DIN EN 1092-1

Flanges and their joints - Circular flanges for pipes, valves, fittings and accessories, PN designated - Part 1: Steel flanges

This European standard specifies requirements for circular steel flanges in PN designations PN 2,5 to PN 400 and nominal sizes from DN 10 to DN 4000. This standard specifies the flange types and their facings, dimensions, tolerances, threading, bolt sizes, flange face surface finish, marking, materials, pressure/ temperature ratings and flange masses.

Flange faces have to be smooth enough to ensure a tight, leak-free seal for bolted flanges.

Type A: flat face

Type B: raised face

Type C: tongue face

Type D: groove face

Type E: spigot

Type F: recess

Type G: O Ring recess

Type H: O Ring groove

ASTM A335 Chrome Moly Pipe

Chrome Moly Pipe has become a standard in the power generation industry and the petrochemical industry, not only because of its tensile strength, corrosion resistance and high-temperature strength, but also because of its cost-effectiveness. Grades P-11, P-22 – P-91 & P-92 are prevalent grades for the power industry, while P-5 & P-9 are the grades utilized in major refinery processing.

Steel pipe world standards

Pipe manufacturing refers to how the individual pieces of pipe are made in a pipe mill; it does not refer to how the pieces are connected in the field to form a continuous pipeline. Each piece of pipe produced by a pipe mill is called a joint or a length (regardless of its measured length). In some cases, pipe is shipped to the pipeline construction site as “double joints”, where two pieces of pipe are pre-welded together to save time. Most of the pipe used for oil and gas pipelines is seamless or longitudinally welded, although spirally welded pipe is common for larger diameters. 1.

Orifice Flanges

Orifice flange for run installation should be so constructed, machined and attached to the that the inner surface of the passage extends through the orifice flange so that there is no recess at the orifice plate. Orifice flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used. The basic purpose for this is to measuring the flow rate of either gases or liquids in the respective pipeline. These flanges are used in various industrial applications and are available in various sizes and materials.
