Product Applications & Usage Scenarios

Diye industrial Threaded Fittings adopt standard threaded connection designs, supporting common thread standards including NPT, BSPP and BSPT. They feature easy installation and disassembly, reliable sealing performance, and enable pipeline connection without welding, making them ideal for connection, direction change, diameter reduction and sealing of various small and medium-sized fluid pipeline systems, especially for working conditions where welding is inconvenient and maintenance is frequent.

Our products are highly versatile and widely used in water supply and drainage, HVAC, fire fighting pipelines, mechanical equipment, instrument supporting, light industry pipelines, small chemical plants, as well as domestic and commercial pipeline systems. They allow quick connection with various small valves, filters, water pumps and instruments, with flexible installation and simple maintenance. As a best-selling pipeline accessory mainly for export and domestic sales by our Chinese factory, we, as a professional manufacturer and reliable supplier, fully meet the conventional and customized needs of different customers worldwide.

Selected Materials & Product Advantages

As a formal China threaded pipe fittings manufacturer, Diye Factory strictly selects high-quality raw materials and rejects inferior or defective materials. We mainly provide two high-grade material options to adapt to different working conditions, and all materials undergo strict physical and chemical tests and performance inspections, complying with quality standards for pipeline accessories at home and abroad.

Material Selection

For conventional non-corrosive, normal temperature and pressure working conditions, we adopt high-quality carbon structural steel and 20# steel, featuring high material strength, stable pressure resistance and excellent cost-effectiveness, suitable for conventional pipelines conveying water, air and oil media; for scenarios requiring high corrosion resistance and rust prevention, we use 304/316L stainless steel, which is acid and alkali resistant, rust-proof and anti-oxidation, ideal for pure water, weak acid and alkali media, food-grade pipelines and humid corrosive environments, with no rust or deformation after long-term use.

Relying on the precision machining technology of Diye's own factory, our Threaded Fittings have high-precision threads with tight engagement, eliminating thread slipping and leakage. They feature regular appearance and smooth inner walls with low flow resistance. As a professional China supplier, we support quick delivery of conventional specifications and customization of non-standard threads and special sizes, meeting both bulk project procurement and small-batch order needs. With direct factory pricing, stable quality and efficient delivery, we provide worry-free and reliable one-stop threaded pipe fittings supply services for global customers.
