Standardisation

All Products are manufactured in agreement with the guidelines set by standardisation institute each over the world similar as the Indian Boiler Regulation( IBR), Manufacturers Standardisation Society( MSS), American Petroleum Institute( API), American Society of Mechanical Engineers( ASME).

Procurement Of Raw Materials

n the manufacturing process we bear sword casting of colorful grades, pristine stell round bars, forging, tackle( nuts & bolts), gaskets, maquillages and also packing accoutrements . We buy all the raw accoutrements from the approved suppliers. 

Quality Assurance

All raw materials are checked by our Internal Quality Assurance Department prior to infusion into the manufacturing process. For example, when we receive steel castings and rods, it is checked and then possed on to stores with an “INWARD PASSED” sign and stamp, if it is rejected it is sent back to the supplier with a G.I.R. note.

Machining

The raw accoutrements is issued to the machine shop for machining through material importunity slips. Stopcock body, bonnet, stopcock seat, spindlesetc. Are machined on centre lathe machine, after which all the factors are checked by vernier callipers or micrometers. In- Process Testing still, the stopcock body and bonet are transferred for Hydrostatic Testing to the testing yard and other factors are transferred to the fitting/ assembling department, If it’s set up to be OK dimensionally and visually.

In-Process Testing

If it is found to be OK dimensionally and visually, the valve body and bonet are sent for Hydrostatic Testing to the testing yard and other components are sent to the fitting / assembling department. All the bodies and bonnets are tested on Motorised Hydrostatic Pumps or on Hand Operated Pumps. A pressure test is carried out as per relevant world standards. The theory being, when the body or bonnet is under pressure there should not be any leakage or drops of the testing and fluid from any portion of the bodies and bonnets. If there is any leakage observed, it is rejected and sent back to the foundries.

Assembly

The proposition being, when the body or bonnet is under pressure there shouldn’t be any leakage or drops of the testing and fluid from any portion of the bodies andbonnets. However, it’s rejected and transferred back to the foundries, If there’s any leakage observed.

Lapping

In some cases lapping of the seats and plugs / other components is done prior to fitting, whereas in other cases lapping is done after fitting.

Testing

After assembly the new complete valve, is sent for hydrostatic testing again. If no leakage is observed, as per the relevant standards, it is sent to the finishing department.

Finishing/Painting

Then the stopcock body face is barred and finished by Sanders and flexible shaft grinders for better appearance and smooth finishing. One fleece of erosion resistant manual( red oxide) is scattered, and if any uneven face is observed a high temperature putty is used, after which named colors for different types of faucets are scattered doubly for a superior face look. Then it should be noted that faucets which are manufactured for IBR blessing are not painted originally. they are offered for examination by the concerned inspectors without makeup, but in a fully assembled stage. The IBR number distributed is also punched after examination, and oils is done only after this.

Final Inspection

After painting, final inspection is done by our Quality Assurance Department / Third Party Inspection Agency, whose responsibility now is to co-relate and check all records relating to the valve concerned. Special attention is paid to co-relate all the serial numbers and in-process quality checks, a valve serial number and then passed on to the packing department.

Packing

In the packing department all the valves are covered with polythene bags and placed into wooden case, with a bed of grass for non-damage of valves. It is then covered and nailed with a packing note and valve users manual / maintenance guidelines for the despatch department.

Despatch

The despatch department checks all the details mentioned in the packing note and the purchase order, and send the package to the godown or to the transporter.
