About Us

ARCELLOR CONTROLS (INDIA). Our brand name ARC-LOK stands for ACURRATE, RELIABLE & COMPLETE SOLUTIONS FOR INSTRUMENTATION VALVES & FITTINGS.

We are one of the pioneers in the manufacture of Instrumentation Tube & Pipe Fittings, Compression fittings, Globe Valves, Needle Valves, Ball Valves, Check Valves, Gate Valves, Valve Manifolds, Air Header, Condensate Pot, Air Filter Regulator, and Erection materials for Hydraulic and Pneumatic applications in India.

The wide applications of ARC-LOK Products are in Power plants, Oil refineries, Petrochemical Plant, Steel Plant, Paper Plant, and Instrumentation industries. Pre-tested raw materials are used in the manufacture of various products, ensuring high quality and timely supply to the Customers. The products are tested and guaranteed as per Advanced Industrial Standards.

Quality Management
The Quality Management System complies with ISO 9001:2008 , ISO 14001 , OHSAS 18001 , CE & PED standards for service range of Design, Manufacture and supply of Compression Tube & Precision Pipe Fittings, Instrumentation Valves and Manifolds. The Fittings are with respect to Pressure equipment Directives. In house design facilities and modern testing set up ensure a confirming product and repetitive accuracy. Qualified work procedures and stringent quality checks at various stages of production ensure quality products.

Best testing facilities like High end profile projector, Impulse and vibration test, and pressure cycling & temperature test for fittings are performed. Our fittings are also tested in accordance with ASTM F1387 and our valves and Manifolds are tested in accordance with MSS SP 99.

For critical applications. Stainless Steel fittings are manufactured as standard, with a unique heat code traceability number, either stamped or etched on each individual fitting. Upon request, full material documentation is available, tracing the stainless steel back to the original cast or melt.

2 test benches for Hydraulic high pressure test to 20,000 psi and pneumatic high pressure tests to 2,000 psi and vacuum test up to 700 mbar.

All critical pipe threads are formed on thread rolling machines. Seating surfaces are burnished to ensure perfect leak tight surfaces. To ensure a leak–tight seal, use of pipe thread sealant on all NPT threads the most effective sealing method is Teflon tape.
