Standard Flanges (Weld-neck, Slip-on, Socket-weld, Lap-joint, Blind and Screwed Types) are manufactured by Dinesh Industries to specifications of ASME B16.5, ASME B16.47, ASME B16.48, BS EN 1092, BS 4504, API-605, API-590, MSSSP44, DIN 2632 to 2638, DIN 2576, 2642, 2527, 2566. Flanges cover a full range of pressure ratings of these specifications (150 – 2500 psi for ASME & PN6-PN400 for DIN / EN flanges). Non-standard flanges are made upto a diameter of 4500 mm and the weight not exceeding 5,000 kgs.
One of the leading Lap Joint flange manufacturers and supplier in India, Dinesh Industries manufacturer Lap Joint Flanges in various types of carbon steel, alloy steel, stainless steel and duplex steel flanges as per customer recognised material standard (ASME/ANSI/DIN). The flanges are also manufactured as per customer specific requirements/drawings.
Dinesh Industries is Lap Joint Flange (LJ Flanges) Manufacturer in India manufacture Class 150 to Class 2500 LJ Flange, type of sealing face RF, FF & RTJ, material in kinds of carbon steel, low temperature carbon steel, alloy steel, stainless steel, Inconel & Hastelloy.LJ Flange is used with stud ends, according to ANSI B16.5/ANSI B16.47 Series A/ANSI B16.47 Series B American Standard. We also manufacture as per DIN Standard, BS Standard, JIS Standard, GOST Standards depends upon our customers requirements & Drawings.
Lap Joint Flanges are similar to other types of industrial flanges, but it does not have a raised face. Lap joint flanges are used in conjunction with a “Lap Joint Stub End”. The total initial cost of a lap joint flange along with a stub end is around one-third higher than that of comparable welding neck flanges. The pressure holding capacity of lap joint flanges is comparatively lower, and the fatigue life for the assembly is only one tenth that of welding neck flanges.
