GIC is the leading Orifice Assembly Manufacturer in India providing reliable solutions for accurate pressure measurement to process industry worldwide.
ORIFICE PLATE WITH WELD NECK FLANGE UNION
The weld neck flange is normally referred to as the “ high Hub” flange. It is designed to transfer stresses to the pipe, thereby reducing high-stress concentrations at the base of the flange. The pressure tappings are provided through the flange at a distance of 1” from the face of the plate (shown in the drawing attached). Weld neck flanges are preferred where radiography on welding is involved.
ORIFICE PLATE WITH SLIP-ON FLANGE UNION
The slip-on flange has a low hub because the pipe slips into the flange prior to welding. It is welded both from inside and out to provide sufficient strength and prevent leakage. The slip-on flanges are bored slightly larger than the OD of the matching pipe.
ORIFICE PLATE WITH MALE-FEMALE CARRIER RING AND FLANGED UNION
The construction is similar to the above except a male-female carrier ring is provided to facilitate pressure tapping through it (corner tapping). This construction is generally used for lower line sizes (normally less than 2”). Carrier rings are also available for bigger sizes on request. Carrier ring machined from single block is also offered in place of male-female carrier.
