Stainless Steel Welded Tubes for Boiler,heat exchanger and condenser
ASTM A249 / GB151
OD:9.5-219.08MM; WT:0.5-5.0MM

Salient Features
Maintenance free
Low life cycle cost
High aesthetic value
Easy & fast installation...

Pressure Test:
100% tested at the appropriate pressure stated under water.
All coils must be flushed and dried after pressure testing

Welded by the Tungsten Inert Gas (TIG) process, no filler rod or any additional metal is used to complete the weld.

At Fine Tubes we inspect all tubes before shipment to ensure that all elements of the customer's specifications have been met. Standard inspections
