ABOUT NUT

A nut which has a threaded hole. Nuts are always used opposite to a mating bolt to fasten a stack of parts together. The two partners complement each other and are kept by a combination of their threaded friction. In nut loose applications where vibration or rotation worked, locking mechanism may be employed. Nut are mostly found in hexagonal shape for the reason being 6 sides give a good granularity for angles for a tool to approach and loosen the fix. /it takes 1/6th of a side to rotation to obtain the next side of the hexagon and grip is optimal. Polygons with more than six sides to not give a requisite grip and polygons less than six sides take more time to be given a complete rotation. Other rotation valves such as wing nuts or captive nuts are available for inaccessible areas.
Nut are graded with strength ratings compatible with their respective bolts so that they are able to support the proof load of the threaded nut. Instinox supplies a variety of nuts from household hardware versions to specialize industry specific designs that are engineered to meet various manufacturing standards.

MANUFACTURING PROCESS OF NUT

In modern fastening technology the cold forming procedure is used to manufacture majority of fittings. In this procedure the fittings is formed, usually in multistage process, by pressure forging then cold extrusion and reducing, or a combination of these three procedures. The term solid or cold forming was used for this type of production method.
Major Steps included in the manufacturing process:-

  • Machining
  • Forming without cutting
  • Cold forming or Hot forming

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. Nut 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 Nut. 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

Each heat and lot of Nut 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.
