ABOUT HEX COUPLING

Hex coupling nuts are those which are used to make up long tie road assemblies from shorter lengths of rod and to facilitate assembly of two fasteners of fittings which of each have external threads. The standards of chemical and mechanical performance are controlled in conformance with ASTM fittings specifications. Standards threads with other threaded series are profiles available by special orders. Hex coupling nuts can also be threaded with two distinctive thread sixes or profiles. Those parts are usually identified as reducing couplings. These hex coupling can be provided when high strength rods are specified. These fittings will meet all the properties called in for those specifications. The rods must be threaded into coupling nut for a distance equal to or greater than the normal thread diameter. Hex coupling has standard finishing and a plain surface with either cold drawn or hot rolled mill finish which depends on the type of bar stock used.

PRODUCTION OF COMPRESSION FITTINGS

Our state of the art factory has 21 CNC Machines, 12 Lathe Machines, 3 Heavy Punch Machines, and 5 Dye Machines for an end to end process at one place. Our production capacity at peak in a 3 shift schedule is 1.3 million pieces of assembled units per month. Added to that we have in house testing facilities like spectro machine, PMI Machine, Mechanical test, Hardness Test, Ultrasonic Testing, Hydrostatic Testing, Pressure testing, and manual inspection of gauge. Our production range also includes instrumentation valves, condensate pots, snubber, manifolds, and custom designed valves. Hex Coupling can be made in NPT, BSPT & BSPP Threads.

The production process can be divided for BODY, NUTS and FERRULES :

  • Body:As per design standard the body is made from hex or round bar which is subject to heat treatment depending on the stature of the bar. Followed by that, the body is machined depending on the thread required by customer.
  • Nuts:Nuts are made in a fairly simple process by a machining of hex bar as per size and thread from a standardized design.
  • Ferrule: Ferrules are the heart of the Hex Coupling. Our specialization lies in the manufacture of an innovative method that makes the ferrules compatible with other manufacturer designs and increases the life of the fitting.

INSTRUMENTATON FITTINGS QUALITY CONTROL

As a Hex Coupling, Instinox is backed by all the possible certifications of a world class mill including ISO 9001:2008, ISO 14001:2007, OHSAS 18001: 2004 & CE-PED 97/23/EC. We are also members of various renowned agencies and Chambers of Commerce including MASSMA, EEPC, FICCI, FIEO, Indian Merchants Chamber etc.Coupled with that i-LOK Hex Coupling are supplied with a default one year product replacement warranty against customer word without any further questions. We are confident because 100% Hex Coupling are tested in house for any defects in quality or workmanship manufacturing. Not even a single fitting can leave the premises without a 3 layer inspection of chemical test, mechanical test, visual inspection, dimension inspection, pressure test, gauge test and conformity to the order. Thus we are generally stuffed with loads of orders for 90 days schedule ahead of time.

Each heat and lot of Hex Coupling is supplied with a material test certificate as per EN 10204 NACE 3.1 standards indicating the chemical and mechanical properties of the fittings along with pressure rating. We also confirm the guarantee of the fittings supplied as per Purchase order specifications and attest the same in the Material Test Certificate. We also welcome any third party inspection from an agency nominated by the customer to comply with NACE 3.2 Certification if required by customer at an extra cost.
