RP Sales serves seven industrial verticals: power plants (IBR boiler tubes), sugar mills (bagasse boiler + evaporator tubes), oil & gas (API 5L line pipe), automotive (cold-drawn precision, ST52), construction (IS 1239 ERW, structural RHS/SHS), water and irrigation (IS 4270 borewell), and OEMs (DIN 2391 hydraulic). Each vertical has its own grade, standard and documentation requirements; we match the right MTC, TPI, and IBR per order.
Power generation
Thermal power plants buy seamless boiler tubes (SA192, SA210 Gr A1/C, SA213 T11/T12/T22), economiser tubes, condenser tubes (SA179, SA249), and high-pressure feedwater piping. IBR Form III-C is mandatory. We supply Maharashtra Seamless, Jindal Saw, ISMT, and Tenaris-origin material with full IBR documentation.
Sugar mills
Bagasse-fired boilers consume seamless boiler tubes (SA192, SA210 Gr A1) and water-wall tubes annually. Evaporator and juice-heater tubes are typically SA179 cold-drawn. Off-season replacement windows are short — we maintain stock for emergency dispatch through the crushing season (October-April).
Oil & gas
Line pipe per API 5L PSL 1 / PSL 2, sour-service NACE MR0175, casing per API 5CT. Hot-rolled seamless and ERW for collection systems and gathering lines. We supply IOCL, BPCL, ONGC, GAIL, and EPC contractors with TPI by SGS / BV / Lloyds as standard.
Automotive & OEM
Cold-drawn precision tubes per DIN 2391 / EN 10305 in ST37.4, ST52, E235, E355. Hydraulic cylinder tubes (BK+S H8). Drive shafts, propeller shafts, structural tubes. Tighter tolerances and consistent batch quality matter more than headline price.
Construction
IS 1239 ERW (medium and heavy class), IS 4923 RHS / SHS for fabrication, scaffolding pipes per IS 4923. Galvanized variants for plumbing and outdoor use. Volume-driven; price-sensitive but quality-floor matters for structural use.
Water & irrigation
IS 4270 borewell casing, IS 12818 uPVC column pipes, IS 1239 medium class for distribution. Galvanized variants for saline groundwater zones. PHED tenders and minor-irrigation department supply.
