PRODUCT DESCRIPTION

Our reducing pipe nipple is manufactured from high‑quality Q235 carbon‑steel pipe, hot‑dip galvanized or epoxy powder coated for rust‑proof performance. One end is male thread and the other end is female reducing thread, perfectly connecting different‑diameter fire‑fighting and irrigation pipes.

Threads are strictly machined according to NPT or BSP standard to ensure tight connection without water‑leakage after assembly. This threaded nipple is welded onto our 3‑meter grooved pipe section in our factory to form engineered pre‑fabricated fire‑piping assemblies.

Key Advantages

Precise NPT/BSP thread machining, smooth thread surface for firm assembly and reliable sealing.
Hot‑dip galvanized / epoxy coated treatment resists corrosion for long‑term service indoors and outdoors.
Factory‑welded onto grooved pipes cuts down field‑side welding work and saves local labor costs for M&E contractors.
Matches ASTM A53 steel pipe, compatible with fire‑protection sprinkler and irrigation pipeline systems following NFPA requirements.
Custom lengths and reducing sizes are available to meet your project‑specific demands.
