ASTM B280 Tp2 Seamless Copper Tube Inner Grooved Fin Tube for Refrigerator Condencer
Datang manufactures low fin tubes for heat exchangers used mainly in LNG facilities, chemical and petrochemical plants, refineries, power plants, renewable energy and naval systems.
Low fin tubes are obtained through a rolling process, which is a cold plastic deformation directly on the outer surface of the tube.
The low finning process greatly increases the surface area of heat exchange.
Materials
- Low-alloy steels
- Carbon steel
- Stainless steel (austenitic, ferritic, super austenitic)
- Duplex alloys (Lean Duplex, Duplex and Super Duplex)
- Monel alloys
- Nickel alloys
- Copper alloys
- Titanium

Dimensional Tolerances
Our company meets the generally required standards for low fin tubes, namely:
- ASTM/ASME B/SB 111 (Copper & Copper Alloys)
- ASTM/ASME A/SA 498/498M (Carbon steel)
- ASTM/ASME A/SA 1012/1012M (Stainless steel)
- ASTM/ASME B/SB 891/891M (Titanium)
Quality Checks
We perform air tests at a range between 10 bar and 18 bar for 10 seconds and/or hydraulic pressure leak tests if requested by the customer.
We perform non-destructive tests (after finning).
Depending on the client’s needs, we are available to perform special tests and treatments.
Dimensional Checks
We measure:
- outside diameter of plain end (D)
- inside diameter of plain end (Di)
- wall thickness of plain end (W)
- diameter over fins (do)
- root diameter (dr)
- inside diameter of fin section (di)
- wall thickness under fin (Wf)
- mean fin thickness (Fm)
- height of fin (Fh)
- fin pitch
We perform a complete visual check.
Packaging
We offer different packaging solutions in order to meet your needs:
- hexagonal and protected bundles
- nylon
- wooden crates and/or cages.
These methods will ensure a safe and organized transportation of your products.
