S30403 Stainless Steel Corrugated Tubes For Heat Exchangers PA Fin Tube
Quick Detail
General Low Fin Tubes Production Capacity | Specifications of Low Fin Tubes('N' Fins) |
Finning Facility: 10 finning machines; | Tube OD: 12.7 mm~25.4mm |
Description
Manufacturing process: The fins are rolled out of outer wall of the plain tubes by a pass roller. Tubes and fins are in same piece tube. We call it"N"fin type.
Tube Materials
ASTM A213 / A213M :Seamless Ferritic & Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes
ASTM A312/ A312M : Seamless, Welded, and Heavily Cold Worked Austenitic Stainless Steel Pipes
ASTM A269/ A269M :Seamless and Welded Austenitic Stainless Steel Tubing for General Service
Quality Test
The integral low fin tube quality is assured by hydrostatic or pneumatic tests, eddy current tests & MARCO tests in order to verify design specifications.
Acceptance Ceritia
WOLVERINE / HPT / GEWA-K & GEWA-KS
Delivery Condition
Tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with varnish.
The desiccants are put into the each package for continental transportation.
Applications
The Integral Low Finned Tubes find the preference in the following industrial sectors:
- 1. Heating systems
- 2. Ventilation systems
- 3. Refrigeration and climate control systems
- 4. Mechanical engineering
- 5. Automotive manufacturing
- 6. Chemicals and pertrochemical and power plant technology
Specifications
Tube and fins consist of same tube and materials as carbon steel , low-alloy steels , stainless steel , brass , copper , cooper-nickel alloys , aluminum bronze , nickel alloys , titanium etc...
