Products

The Fuel injection pipes exported by us are made from Seamless Tubes and Forged Nuts manufactured by our parent company M/S Gandhi Special Tubes Ltd. The seamless tubes are scale free, bright, soft, annealed tubes with a very clean bore (mirror finish) and having surface roughness value below 2 microns Ra. These pipes are fully Fabricated as per O.E Specifications & Designs, i.e. Pipes are Forged, and fitted with forged Nuts and bending is done as per O.E drawings or samples.

PERW (Precision Electric Resistance Welded) Tubes exported by us are manufactured by our parent company, M/S. Gandhi Special Tubes Limited (ISO/TS 16949:2009 and ISO 9001:2008) set up its plant in technical collaboration with BENTELER STAHL/ROHR GMBH & CO.AG of Germany. The project involves manufacturing of small diameter precision welded steel tubes.

•   DIN 2394
•   EN 10305-2
•   SAEJ 526
•   SAEJ 356 etc or equivalent

Strict measures are taken to ensure Scale free and bright tubes with high degree of internal cleanliness conducting following tests:

•   Bubble Test to check Leakages with dry nitrogen under water @ 70 bar pressure.
•   Tensile Test
•   Flattening, Flaring, Bending Test
•   Eddy Current Test
•   Micro hardness Test
•   Chemical Composition
•   Metallurgical & stereo Microscopy
•   Dimensional checks

•   The precision welded steel tubes are manufactured using the latest and most advanced technology. Raw material is DD/EDD grade low carbon steel CRCA coils. The process involves continuous Forming, Direct Current Welding, and Sizing by passing through a set of stretch reducing rolls and thereafter followed by bright annealing in continuous roller hearth Furnace under reducing atmosphere. The resultant tubes are Soft, Scale free and Bright having excellent physical properties.
•   The tubes are pressure tested at @ 70 kg/cm2 pressure with dry nitrogen under water before straightening and finishing operations. The continuous manufacturing process enables supply of the tubes in straight lengths & coils up to 1000 meters.

Tube Fittings & accessories manufactured and Exported by us are cold forged. The raw material used for manufacturing these tube fittings are as per International Standard.

Applications for Tube Fittings & accessories

•   Stringent quality control is maintained during and after manufacturing process to ensure that the products are as per O.E.M standards and specifications.
•   High Degree of Reliability ensuring Zero Failures on account of Cracked nuts
•   Greater Shear Strength than Machined Nuts
•   Excellent Surface Finish which not only gives better looks to the nuts but improves product life
