Instrumentation Supplier for the Panipat Refinery & Petrochemical Belt

Hazardous area supply is mostly about not assuming

The Panipat refinery and petrochemical belt, and the contractors and fabricators who serve it, work to a standard that very little else in northern Haryana requires. Areas are classified. Materials are specified rather than chosen. Certificates are checked, not filed.

In that environment the difference between a good and a bad supplier is not price or even delivery. It is whether the supplier asks a question when the datasheet is incomplete, or quietly assumes something and ships it. An assumption discovered at site is a delay; an assumption discovered after installation in a classified area is considerably worse.

We would rather come back with three questions and quote two days later than send something that has to be returned. On this belt that is not caution, it is the minimum standard.

What has to be right before manufacture

Zone, gas group and temperature class, from the drawing. Not inferred from the process, not assumed from the plant. These come off the area classification drawing, and an instrument certified for IIB is not acceptable in a IIC area regardless of how well it performs.

Wetted material against the actual service. SS316L is not a universal answer in hydrocarbon and sour service. Chlorides, H2S and some process streams need something else, and the wrong choice fails in a way that matters here.

Thermowell wake frequency, calculated not assumed. On high-velocity steam and gas lines a well that fails the ASME PTC 19.3 TW calculation eventually breaks off inside the pipe. In a refinery that is a release, not a lost instrument. We run the calculation free before you order.

Certification that will survive an audit. CCoE / PESO certificates supplied with the goods, material test certificates traceable to the heat, and calibration certificates with as-found readings. Assembling this afterwards is far harder than getting it with the delivery.

Cable entries and glands as part of the certified assembly. A certified enclosure with an uncertified gland is not a certified installation, and it is a common finding.

Instrumentation we supply into the Panipat belt

For classified areas: flameproof pressure and temperature instruments, transmitters and switches specified against your zone, gas group and temperature class, with CCoE / PESO certificate copies shipped with the goods and Ex d glands supplied as part of the assembly.

For hydrocarbon and utility service: pressure gauges and transmitters with wetted materials matched to the stream, diaphragm seals where the medium demands them, and gauges with proper over-range protection.

For temperature measurement: bar stock thermowells machined from solid with no weld in the wetted section, wake frequency calculation run free, RTDs and thermocouples with spring loading, and head-mounted transmitters where cable runs are long.

For contractors and fabricators: supply against a project tag list with the documentation package the end client will demand, delivered together rather than in pieces.

Where packing machinery fits on this belt

Less than on other pages, and we would rather say so than stretch the point. A refinery does not run a carton line. What it and its contractors do have are stores, workshops and despatch points that pack spares, fabricated items and returned equipment.

For those, semi-automatic strapping and carton sealing on a bench is the right scale. Drum handling matters more — drum carriers and hydraulic pallet trucks rated for full drums are used constantly around lubricant, chemical and effluent handling.

Where a contractor packs and ships fabricated assemblies, strapping for crated and bundled loads with tension set for the item is what is actually needed. We supply that, and we do not pretend a refinery needs an in-line packing system.

Working with a plant or a contractor

Supplying a plant directly? Send the tag list with the area classification data and the material specification. We quote against it, ask where it is silent, and supply with the full certificate package.

Working as an EPC or fabrication contractor? Tell us the end client's documentation requirements at enquiry stage, not at delivery. Certificates that have to satisfy a refinery client are best organised before manufacture rather than chased afterwards.

Maintenance and shutdown work? Shutdowns are planned, and instrument requirements are usually known weeks ahead. Send the list early and we schedule it so it lands before the window rather than during it.
