WHITE METAL SOCKET TYPE WINDING ROPE CAPPEL ‘N MC’ White Metal Socket type Cappels are supplied for all rope and loads. They conform to IS : 7587 (Part II) — 2006. They are used for connecting winding rope to the suspension Gear. The length of the taper of the basket is usually not less than 6 times and not more than 8 times the diameter of the rope and the angle of taper is between 3° and 6° .

'NMC' Whirling Hygrometer Consists of two thermometers with least count of 0.50 C and range 0-50 C and are mounted side by side in a plastic wooden frame.

Select the Magnehelic gage for high accuracy - guaranteed within 2% of full scale. Using simple, frictionless Magnehelic movement, it quickly indicates low air or non-corrosive gas pressure - either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems. It’s inexpensive, too.

Tub Couplings are manufactured Conforming to DGMS circular No. 1 of 1986

Toggle Joint couplings are designed to provide a quick make-and-break joint. Housings are hinged for one-piece handling.

It consists of an outer non-rusting tube inside which a close fitting rod slides. On this rod a scale is graduated with 1 mm least count by etching operation. The scale does not fade because of etching.

1. ‘NMC’ Prop puller primarily is meant for pulling the props etc. from goaf area. Alternatively it can be used for felling the trees, pulling the machines.

The pressure on which the clamp can be used will vary with the type of clamp, pipe OD, medium etc. Use the following table as a guide (recommended working pressure, in bars, under ideal circumstances) :

Style 77S Stainless Steel Coupling is designed with cross Rib construction for 2 inch and 3 inch and for other sizes they come with plain surface. Couplings are cast of high quality Type 304SS for corrosion resistance and strength. Alternatively, Couplings with SS 316 castings are also available.

It is one band clamp (SS Half circle repair clamp) with partial gasket. For the repair of small holes in pipes with OD from 21 mm. up to 323.9 mm. Working range 4 mm. for smaller size & up to 10 mm. larger sizes Available forW. P. up to 300 P51(20.4 Bar)

Smoke Generator consists of Glass tube containing granulated pumic stone saturated with anhydrous tin or titanium tatrachioride. Glass tube is fitted with a rubber aspirator bulb thro’ rubber tube at one end & the other end is in the form of a tip coyèred by a rubber cap.

They are of Steel Construction provided with soft iron jaws. Centre Bolt adjustment eliminates slit.

'NMC' Safety Hook operation and detaches the Cage or skips from the winding rope in the event of an over wind.

INTRODUCTION: Rotary Extensometer In same areas conventional method of Roof Testing is not possible or convenient. There is no visual indication of how close is the system to ultimate failure.

The quality and performance of the gasket and sealing rings is a crucial factor in the efficiency of any compression-fit pipe joint. NMC are able to offer gaskets & sealing rings in a variety of designs and compounds to suit a wide range of applications.

(AS PER DGMS TECHNICAL CIRCULAR / 04) Dated 28.09.2010 NMC’ Hydraulic Cappel Banding Machine has been developed to replace the traditional method of Sledge Hammering during Banding and Disbanding of FWRC. It should be used at the time of re-capping of FWRC.

Pitot Tube is standard air velocity meter. It consists of two concentric tubes. Inner one measures total pressure existing in the fluid stream, the outer measures static pressure only. When these tubes are connected to Manometers only the velocity pressure is registered. This pressure is a measure of linear velocity of gases.

Improved ‘N MC’ Water Gauge comprise two no 6mm straight corning glass tubes terminating into a brass block with a connecting passage. One limb is open to atmosphere & other is connected to fan drift. A tap is provided to close the connection while taking reading. A scale with adjusting screw is mounted behind the glass tubes. A spirit level helps in keeping the instrument vertical.

NMC’ PE Coupling is mechanical pipe Coupling meant for plain end Metric uPVC Pipes. It comprises two flanges (MCI/Ol), one central sleeve (M.S), two wedge section Rubber Rings. one set of galvanised ‘D’ Bolt & Nut.

These Clamp can be easily and quickly be assembled by just tightening four captive bolts and guarantees leak-proof repair of pipes. Useful for taking branch connections off existing water mains even under pressure. Range : DN50-DN300.

Maxi Range offers the possibility to cover a much larger diameter range than in the past and more pipe materials can be joined whether in steel, ductile iron, cast iron, asbestos cement, PVC or almost any other rigid pipe material.

A range of tapping Tees that allows flanged branched connections to be made to an existing water main, whist it remains pressurized. Kwik Tee can be used in conjunction with all popular pipe materials. Range : DN80-DN300.

A range of tapping clamps that provides a quick, cost effective method of installing or replacing service pipe connections, whilst under operating pressure. Kwik Tap can be used with standard drilling equipment.

KWIK Finger Repair Clamp These repair clamp provide an economical and permanent method of repairing damaged pipes from pin hole leaks to full 360° circumferential breaks. These clamps are light weight and easy to handle. Range : DN40-DN600.
