Spiral wound metallic gaskets to ASME B16.20 for raised face (RF), tongue & groove (T&G), and male & female flanged joints across all pressure classes. Constructed from alternating layers of pre-formed metal strip (SS 304/316/321 or special alloy) and soft filler material (flexible graphite or PTFE), with carbon steel or SS centering/outer ring and optional solid metal inner ring. Supplied for all NPS sizes from ½" to 60" (DN 15 to DN 1500) across ASME Class 150 to 2500: the industry standard gasket for turbine casing joints, steam inlet flanges, steam piping, heat exchanger nozzles, and pressure vessel joints.
Primary Industrial Application
Universal gasket for turbine overhauling and plant maintenance: turbine casing split-line joints, steam inlet and exhaust flanges, HP/LP bypass piping, heat exchanger nozzle flanges, pressure vessel manholes, and all standard ASME B16.5 / B16.47 flanged piping. Essential stock item for plant engineers and procurement managers, required in every planned shutdown and overhaul. Supplied individually to drawing or as complete flange gasket sets for a valve, turbine, or exchanger. Filler selection: flexible graphite for steam, water, and high-temperature service; PTFE for chemical and corrosive service.

Mechanical dismantling joint designed for easy disassembly and reassembly of piping sections during maintenance without damaging adjacent components. Provides axial adjustment for quick removal and reinstallation of pumps, valves, and equipment.
Application: Pump and compressor suction/discharge connections, valve maintenance points, water treatment systems, and industrial piping requiring regular equipment removal and reinstallation.
Compression gland packing in graphite, PTFE, and PTFE-graphite braided constructions for valve stem sealing, pump gland boxes, and rotating shaft seals. Supplied as cut rings or coiled rope in square cross-sections from 3 mm to 50 mm. Pure flexible graphite packing for high-temperature steam valve stems; PTFE packing for chemical and corrosive service; PTFE-graphite hybrid (graphitized PTFE) for combined chemical resistance and thermal conductivity across both rotating and reciprocating applications. Asbestos-free throughout: fully compliant with current Indian and international environmental regulations.
Application: Universal maintenance consumable across all plant types: steam turbine auxiliary valve stem packing (gate, globe, and control valves), centrifugal pump gland boxes, reciprocating pump plunger seals, agitator shaft seals, rotary compressor shaft seals, and heat exchanger channel cover joints. Supplied as rope coil (specify cross-section and length) or as pre-cut rings (specify shaft OD, stuffing box ID, and number of rings). Most frequently procured alongside turbine overhauls, valve repacking during planned shutdowns, and pump mechanical seal conversions where gland packing is retained.
Spring-loaded safety relief valves (SRV/PSV) for overpressure protection of steam boilers, pressure vessels, steam headers, heat exchangers, and process piping. Supplied to API 526 (flanged steel SRVs for process plant), ASME Section I (power boiler safety valves, snap-action), and ASME Section VIII (pressure vessel relief valves). Three types: Conventional spring-loaded (standard), Balanced bellows (variable or high back-pressure service), Pilot-operated (high set-pressure accuracy, minimum blowdown, large orifice). Body materials from carbon steel through SS 316 and exotic alloys. IBR certification available for Indian boiler and steam system applications.
Application: Mandatory on every pressure vessel and steam boiler in Indian plants: required under IBR (Indian Boiler Regulations), Factories Act, and IS/ASME codes. Critical applications: steam boiler drum SRVs (ASME Section I / IBR), turbine steam inlet header SRVs, lube oil system relief valves, heat exchanger shell-side relief, hydraulic accumulator safety relief, and thermal relief valves (TRVs) on blocked-in liquid lines. Supplied as direct OEM-matched replacements (specify make, model, set pressure, orifice designation, and inlet/outlet size), or as new installation valves with sizing calculation to API 520.
