Stainless Steel Corrugated Tubes For Heat Exchangers ASTM A213 Seamless Tube
Quick Detail:
| General Low Fin Tubes Production Capacity | Specifications of Low Fin Tubes('N' Fins) |
Finning Facility: 10 finning machines; Daily capacity up to 3000 meters; | Tube OD: 12.7 mm~25.4mm Tube Length: 18 meters max. Fin Height: 1.2 mm ~2.77mm Fin Thickness: appr. 0.3mm Fin Pitch: 30 FPI /28 FPI/ 26 FPI/ 36 FPI /43 FPI |
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
Delivery Range of Low Fin Tubes
We can provide the integral low fin tubes with un-finned section gaps( 5mm Min.) in the middle of core tube OR bent with designed Bend Radius.
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:
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...
