Tolerances
We offer TP316L welded stainless steel tube conforming to ASME SA 249 / ASTM A249, outside diameter and wall thickness tolerances should be controlled according to SA249 or ASTM A1016, aiming to offer closer tolerances welded tubes, specific details on tolerances
Application
ASME SA 249 TP316L stainless steel tube is applied in condenser, boiler, super heater and heat exchanger and other pressure equipment, TP316L stainless steel has high strength and corrosion resistance characteristics compared to typical Austenitic stainless steel 304, the tubes are able to work under high temperature and corrosive environment, of course TP316L tube is a good option, and it is durable and cost effective.
