How our manufacturing process works
Planning
We start by reviewing your specifications, standards and
drawings in detail.
Threads, materials, pressure class and documentation needs are all confirmed before we cut any steel.

Build-up
Raw pipes are sourced and checked with mill certificates, then scheduled onto the right CNC and automatic threading lines. Our team plans the most efficient route for your mix of sizes and quantities.
Implementation
Cutting, threading, machining and surface treatment are carried out step by step according to your order. In-process inspections keep dimensions and threads within tolerance so everything fits on site.
Why Choose Stainless Threaded Fittings
Corrosion Resistance that Lasts
304/304L and 316/316L stainless options resist rust, chemicals, and cleaning agents—ideal for wet, sanitary, or coastal environments.
Strong & Dimensionally Consistent
Tight tolerances and robust wall thickness options help fittings maintain integrity under pressure and temperature cycling.
Hygienic & Cleanable
Low-carbon and polished options help minimize crevices and facilitate washdowns in food, beverage, and pharma applications.
