天天捕鱼This data sheet applies for seamless and welded tubes of non-alloy steelwith specified elevated temperature properties.
天天捕鱼This tubes are used for pipe lines beyond the DGRL TR1" and pipe lines of class I to III TR2". Their application is usual up to
天天捕鱼300 °C.The permitted pressure should not exceed 160 bar.
Delivery condition N=normalizing incl. normalizing forming
a For wall thicknesses larger than 60 mm the mechanical properties have to be agreed.
天天捕鱼b applies only for testing class TR2
天天捕鱼1" Normalizing: Holding time 1 minute per mm plate thickness, minimum 30 minutes
2" Stress relievinganneal: Holding time 1-2 minutes per mm plate thickness, minimum 30 minutes
Standard welding processes for these steel gradesare:
TIG-welding Arc welding E"
MAG-welding massive wire Submerged arc welding SAW"
