Corrugated Slot Heat Exchanger A179 Carbon Steel Seamless Tube
A179 seamless carbon steel corrugated slot heat exchangers tube
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. And 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. It will be delivered when 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.
It suits to many areas such as Heating systems, Ventilation systems, Refrigeration and climate control systems, Mechanical engineering, Automotive manufacturing, Chemicals and pertrochemical and power plant technology
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
Popular Tube Materials:
ASTM A106 / 106M : Seamless Carbon Steel Pipe for High-Temperature Service
