Plate Flanges, which are of wide variety, are manufactured mainly from plates. They are conforming to national & international standards and they are hubless. Plate flanges are produced from quality mill plates. Before cutting pieces out of plates, each plate is checked for serious laminations. They should be virtually free of voids, non-metallic inclusions and other defects. Another important property of plate is its weldability and hardenability. For more critical application of flanges, the hardness, strength and impact properties are also important factors. These properties vary through, along and across the section of the product as a result of temperature and micro structural variations during hot rolling, cold rolling or quenching and cooling. Steel can be combined with other metals to form alloys, which can make them corrosion resistant, stronger or lighter.

Slip-On Flange

Slip-On Plate Flange is a popular type of pipe flange. 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 onto different pipes. Welding reduces fabrication costs of these pipes. The two ends of the pipes are then connected with the help of fasteners. These are available in wide variety of sizes and applications. They can be custom made as per the requirement of the clients.


They are conforming to the following National and International Standards :

  • Type : Slip-On Plate Type Flange
  • Material : Carbon Steel : BIS 2062, BIS 2002, ASTM A515 GR. 60/70 & Stainless Steel : ASTM A240-ASME SA240 TP 304/304L/316/316L
  • Dimension : ASME-ANSI B16.5, ASME-ANSI B16.47, AWWA C207, BIS 1560, BIS 13159, BS EN 3293, BSI 4504, BS 10, DIN 2527, DIN 2576
  • Size Range : 15 NB To 1200 NB

Blind Flange

Blind Plate Flange is round plate which has all of the relevant bolt holes but no centre hole. They are used for covering or closing the end of a pipe. It also permits easy access to the interior of a pipe line once it has been sealed and must be reopened. These flanges are ideal for lower pressure applications. These are available in wide variety of sizes and applications. They can be custom made as per the requirement of the clients.


They are conforming to the following National and International Standards :

  • Type : Blind Plate Flange
  • Material : Carbon Steel : BIS 2062, BIS 2002, ASTM A515 GR. 60/70 & Stainless Steel : ASTM A240-ASME SA240 GR. 304/304L/316/316L
  • Dimension : ASME-ANSI B16.5, ASME-ANSI B16.47, AWWA C207, BIS 6392, BIS 1560, BIS 13159, BS EN 3293, BS EN 4504, BS 10, DIN 2527, DIN 2576
  • Size Range: 15 NB TO 1200 NB

Lap jointing Flange

Lap Jointing Plate Flange slide over the pipe and are most commonly used with stub end Fitting. A pipe is typically welded to the stub end and the Lap Joint pipe flange is free to rotate around the stub end. The benefit of this is that there will not be any issues with bolt hole alignment. Lap Joint pipe flanges are often used for applications that require frequent dismantling. Coastal Flange provides Lap Joint pipe flanges in all material grades, specifications and sizes. These are available in wide variety of sizes and applications. They can be custom made as per the requirement of the clients.

    They are conforming to the following National and International Standards :
  • Type : Lap Jointing Plate Type Flange
  • Material : Carbon Steel : BIS 2062, BIS 2002, ASTM A515 GR. 60/70 & Stainless Steel : ASTM A240-ASME SA240 GR. 304/304L/316/316L
