Indexable Threading Inserts for Steam, Gas and Water Pipes Usage （NPTF/BSPT）

Carbide indexable threading inserts dedicated to pipe threads (NPTF/BSPT) adopt corrosion-resistant carbide substrates and multi-layer composite coatings. They are developed specifically for machining sealing threads in pipe systems for steam, gas and water supply. Through precision grinding, the inserts form accurate 55° or 60° pipe thread profiles. Combined with optimized chip breaker groove design, they ensure smooth chip evacuation when machining pipe materials such as cast iron, cast copper and stainless steel. Strictly complying with international pipe thread standards including R/Rc, NPT and G, the product delivers excellent thread sealing performance with a sealing pressure of over 5MPa, fully meeting the sealing requirements of various fluid conveying systems. It is an ideal choice for mass production of pipe components.

● Precision Sealing Threads: Strictly comply with international pipe thread standards to ensure thread fitting precision and sealing reliability.
● Superior Corrosion Resistance: Dedicated substrate material and coating adapt to humid working environments with steam, water vapor, etc.
● Efficient Machining Performance: Optimized groove design maintains stable cutting performance when machining pipe materials.
● Long Service Life: Special wear-resistant coating ensures ultra-long service life even when machining materials like silicon-containing cast iron.

● Steam Pipe Systems: Machining of sealing threads for components such as boiler pipes and steam valves.
● Gas Conveying Pipes: Manufacturing of threads for key components such as gas valves and pipe joints.
● Water Supply Systems: Machining of tapered pipe threads for water meter joints, fire hydrants and water supply pipe fittings.
● Chemical Pipes: Manufacturing of threads for corrosion-resistant materials in components such as chemical equipment pipes and valves.
