Specification Standards for Heat Exchanger Tubes

EN 10216-5*

Seamless steel tubes for pressure purposes

EN 10217-7
Welded steel tubes for pressure purposes
Technical Delivery Conditions - Part 7: Stainless Steel Tubes.

This standard will replace most of the standards for welded stainless tubes and pipes for pressure purposes within the CEN countries.
It is similar to DIN 17457 and SS 219711.

The standard prescribes 100 % non-destructive testing. This gives a possible design utilization of 100%, and a weld factor z = 1.0. Heat treatment may be omitted if agreed. The standard inspection is normally in accordance with EN 10204 3.1.B.

ASTM A 249/A 249M
Welded austenitic steel boiler, super heater, heat exchanger and condenser tubes.

A 213 / A 213M

Seamless ferritic and austenitic alloy steel boiler, superheater and heat exchanger tubes

ASTM A 269
Seamless and welded austenitic stainless steel tubing for general service. ASTM

A 789/A 789 M
Seamless and welded ferritic/austenitic stainless steel tubing for general service.

ASTM B 674*
Standard specification for UNS N08904 and UNS N08925 welded tube.

*Tubes of these grades can also be supplied according to the common specifications A 249 and A 269 for austenitic iron-based grades.
