Tubulars, line pipe and protection for upstream and midstream.
From well construction to transmission, oil and gas projects rely on steel tubulars and pipe that hold pressure, resist corrosion and meet API specifications. Niltech Global supplies casing, tubing and drill pipe, line pipe with factory coatings and field-joint systems, and the radiography products used to qualify welds.

- Casing, tubing and drill pipe to API specifications
- Line pipe with 3LPE, 3LPP or FBE coating
- Field-joint protection matched to the line coating
- Radiographic films and NDT consumables for weld inspection
Divisions involved

- Coatings, Polymers & Advanced MaterialsPowder and liquid coatings, polymer raw materials, masterbatch and MDF surface solutions.
- Inspection & NDTIndustrial radiographic films, radiography equipment and NDT consumables for weld and component inspection.
Relevant products
Grouped by product family. Each product page lists scope, standards and what to include in an inquiry.
- SSAW Steel PipeSpiral submerged-arc welded pipe formed from hot-rolled coil — an economical route to large diameters.
- LSAW Steel PipeLongitudinal submerged-arc welded pipe formed from plate, for large diameters, heavy walls and high pressure.
- ERW Steel PipeHigh-frequency electric-resistance welded pipe for small and medium diameters with consistent wall thickness.
- Seamless Steel PipePipe without a weld seam, for high pressure, high temperature and critical service.
- CasingPipe that lines the wellbore, isolates formations and carries the pressure loads of the well.
- TubingProduction tubing that carries oil and gas from the reservoir to surface inside the casing.
- Drill PipeSeamless pipe with welded tool joints that transmits torque and drilling fluid to the bit.
- CouplingsThreaded couplings machined from seamless coupling stock to join casing and tubing.
- Premium ConnectionsGas-tight proprietary connections with metal-to-metal seals for demanding wells.
- 3LPE Pipeline CoatingThree-layer polyethylene — FBE primer, copolymer adhesive and polyethylene topcoat — for buried pipelines.
- 3LPP Pipeline CoatingThree-layer polypropylene for higher operating temperatures and heavier mechanical demands.
- Fusion Bonded EpoxyThermosetting epoxy powder for pipeline corrosion protection and general industrial coating.
- Internal Epoxy CoatingsLiquid epoxy linings that improve flow in gas lines and protect the bore of water pipe.
- Heat Shrink SleevesCross-linked polyolefin sleeves that shrink over the girth weld to form a sealed, bonded joint coating.
- Cold Applied TapeTape systems applied without heat for field joints, fittings and coating repair.
- Field Joint Liquid CoatingTwo-component solvent-free epoxy or polyurethane applied by brush or spray at the field joint.
