Nipolet Manufacturer in India
Sawariya Metal Industries is a manufacturer, supplier, stockist and exporter of Nipolet in stainless steel, carbon steel, alloy steel, duplex, nickel alloy and other grades, in a wide range of sizes and pressure ratings.
A nipolet is a one-piece fitting combining a weldolet and an extended nipple, used for valved vents, drains and instrument take-offs.
Olets are forged branch outlet fittings welded onto the run pipe to create a reinforced branch connection. They are a compact, cost-effective alternative to reducing tees and allow branches to be added at any position along the run pipe.
Key Features of Nipolet
Integral Nipple
Weldolet and nipple in one piece.
Valve Connection
Ideal for small vent and drain valves.
Integral Reinforcement
Designed to reinforce the run pipe at the branch.
Cost Saving
Lighter and cheaper than a full reducing tee.
