Factory notes
Practical notes on OEM drawings, materials, threads, and export machining.
How bulkhead fittings fail in the field — and what to put on the print
Most bulkhead problems are print problems: hole size, seal stack, or thread mix-ups. Here is what to freeze before you RFQ.
Plating choices for carbon steel pipe fittings in OEM programs
Finish is part of the material decision. Use this short guide before you freeze plating on a carbon fitting print.
Passivation and galling notes for stainless pipe fittings
Stainless solves corrosion and creates new assembly risks. Here is what to specify so parts seal without seizing.
Matching hex nuts and fittings on the same thread standard
Hardware fails quietly when the nut and fitting were gauged to different assumptions. Quote them together when the stack is special.
Forging vs CNC for OEM pipe fittings: choosing the route
Process route sets tooling cost and piece price. Use volume and geometry to pick forging/heading or CNC without guessing.
What an OEM RFQ email should include (short template)
Copy this RFQ skeleton when you email drawings. Clear inputs get clearer manufacturability notes back.
What to put on a pipe fitting drawing before you ask for a quote
Clear prints get faster quotes. Use this checklist for threads, material, finish, tolerances, and file formats before you send an OEM fitting RFQ.
Carbon steel or stainless for custom fittings: a practical pick list
Material choice drives corrosion life, machining time, and price. Use this pick list before you freeze an OEM fitting print.
Thread standards we check before shipping OEM fittings
Wrong threads stop an assembly line. Here is how we read the print and verify threads before OEM fittings leave the factory.
