HIGHER MALLEABILITY

"UNIK" Brand Pipe Fittings withstand higher internal and external pressure without development of cracks as these are produced by using better melting characteristics and heat treatment procedures to provide better ductility.

EFFECTIVE GALVANIZING

"UNIK" Brand Fitting are galvanized by highest purity Zinc in the Virgin form by controlled hot dip process. Therefore, these have uniform, clean and continuous coating of Zinc on both internal and external unmachined surface without any black spots and as well as acid spots. In "UNIK" Brand Pipe Fittings, The thickness of Zinc coating exceeds the minimum specified in the Indian Standard, so as to provide added resistance to corrosion in abnormal weather conditions.

CHAMFERING

"UNIK" Brand Pipe Fittings are chamfered slightly at each thread opening for easy entrance of pipe and correct first thread engagement.

PRECISION THREADING

"UNIK" Brand Pipe Fittings are threaded after galvanizing in order to keep the threads clear and free from dregs. All outlets are threaded simultaneously with the help of HSS ground taps on automatic threading machines to ensure perfect thread alignment at correct angles so "UNIK" Brand Pipe Fittings have threads matching the theoretically correct profile.

MATERIAL

Blackheart malleable cast iron as per IS : 14329-1995 grade BM-300.

THREADS

Threaded as per IS : 554-1999, parallel female and taper male threads.

FINISH

Galvanized Finish tested in accordance with provisions contained in IS-4759-1996.

TEST & WORKING PRESSURES

"UNIK" Brand Pipe Fittings are tested for leakage at an internal hydraulic pressure of 20 kgf /cm2 or at an internal air pressure of 7.5 kgf/cm2. The maximum working pressure for water is 20Kgf /cm2 and for oil, steam (saturated) gas, air, it is 11 kgf /cm2 at ambient temperature.

QUALITY CONTROLS

The process controls are rigidly enforced throughout the production time to ensure that finished goods are of the highest quality.
