Yes, we can manufacture custom pipe fittings directly from your DWG design files. ZheJiang Dream Industry Limited provides comprehensive custom CNC machining, OEM, and ODM services, processing 304 and 316L stainless steel, carbon steel, brass, and copper into precise elbows, tees, reducers, couplings, and custom threaded or welded connectors based on your exact CAD specifications.
Transforming a DWG design file into a physical, high-pressure pipe fitting involves a rigorous manufacturing workflow. Once your DWG file is received, our engineering team conducts a detailed design review to optimize the geometry for CNC turning, milling, or thread processing. We ensure compliance with international standards such as ASME B16.9, ASME B16.11, and DIN/JIS, while maintaining tight dimensional tolerances up to ±0.03mm.
For demanding environments, material selection is critical. Our 316/316L stainless steel options provide superior chloride and marine-grade corrosion resistance, while our 304 stainless steel offers cost-effective oxidation resistance for food processing and general plumbing. During production, we implement 23 in-process quality inspection steps, including First Article Inspection (FAI) and full dimensional checks. This controlled process keeps our manufacturing defect rate below 0.3%, ensuring that every threaded, socket weld, or butt weld fitting performs reliably under high-pressure conditions (up to Class 2500 or 9000# for forged series).
Our practical capability is demonstrated through successful international projects. For example, we completed a custom Valve Handwheel and Pipeline Supply project for an industrial pipeline system client in the United States, delivering 8,000 pieces with consistent dimensional accuracy. Additionally, we support custom surface treatments including pickling, passivation, electropolishing, and sandblasting to enhance the corrosion resistance and service life of the finished components.

What file formats do you accept for custom pipe fitting production?
We accept 2D and 3D technical files including DWG, DXF, PDF, STEP, IGS, and STP. Our engineering team utilizes these files directly for programming our CNC machining centers and lathes.
How do you verify the material quality and dimensional accuracy?
Our facility is ISO 9001 certified. We perform raw material inspections, First Article Inspections (FAI), in-process inspections across 23 steps, and final dimensional checks. Material certificates and RoHS/REACH compliance documentation are available upon request.
What are the minimum order quantities for custom machined fittings?
We provide flexible MOQ options. For initial prototyping and sample verification, we support orders of 1 to 10 pieces. Standard custom production runs typically start at 50 to 500 pieces, while mass production covers runs of over 1,000 pieces.
ZheJiang Dream Industry Limited delivers reliable, drawing-based manufacturing solutions for global industrial clients requiring custom pipe fittings.
