Tube & Pipe Fabrication
Coiled Tube & Tube Coiling Services China
Custom tube coiling — helical coils with controlled diameter, pitch and end geometry for fluid routing and compact assemblies.
Direct answer: Tube coiling services at Balford wind tube into helical coils with controlled coil OD, pitch and end geometry for fluid routing, heat exchange and compact packaging. We review material, wall and coil geometry before quoting, and can deliver coiled tube as finished assemblies.
What Is a Coiled Tube?
A coiled tube is a length of metal tube wound into a helix, either as a finished coiled tube assembly or as a compact delivery form for tube that is later cut, bent and end-formed. Balford produces coiled tube in stainless steel, copper, brass and carbon steel, with coil OD, pitch, number of turns, leg lengths and end forms set by the drawing. Typical uses are fluid and refrigerant routing, heat-exchange coils, sensor and instrument tubing, and compact packaging inside equipment.

Core Capability: Tube Coiling
Helical coils
Controlled coil OD, pitch and number of turns.
Leg and end forms
Straight legs and end forms to the drawing.
Coil assemblies
Cut, formed and assembled coils from one supplier.
Material variety
Stainless, carbon steel, aluminum, copper and brass.
Engineering Review for Coils
Coil vs tube geometry
Coil diameter relative to tube bend limits drives feasibility; confirm material and wall early.
Pitch and turns
Pitch consistency and turn count are set by the drawing and held in tooling.
End geometry
Straight legs and end forms are planned so the coil fits its assembly.
Springback
Coiling springback is compensated in tooling and confirmed on first pieces.

Frequently Asked Questions
What is tube coiling?
Tube coiling winds tube into helical coils — commonly for fluid routing, heat exchange or compact packaging. Coil diameter, pitch and end geometry are controlled to the drawing.
What tube materials do you coil?
Stainless steel, carbon steel, aluminum, copper and brass tube are the common choices; material and wall are confirmed with the coil geometry before quoting.
What coil geometry can you produce?
Coil OD, pitch, number of turns, leg lengths and end form are set by the drawing. Tight coils need smaller bend radii relative to the tube, so feasibility is reviewed against material and wall.
Do you offer coiled tube as an assembly?
Yes. Coiled tube can be cut, end-formed and assembled with fittings so you receive a finished coil assembly.
Where are coiled tubes used?
Typical uses include fluid and refrigerant lines, heat-exchange coils, sensor and instrument tubing and compact equipment packaging.
What do you need to quote?
Coil OD, pitch, number of turns, tube material, OD, wall, leg or end geometry, and quantity. A drawing or 3D model is the clearest input.
