Boiler system ASTM A178 grade A ERW Welded steel pipe

ASTM A178 pipe and tube are mostly to be used in boiler tubes, boiler flues, superheater flues, and other safety applications. There are three steel grades for ASTM A178:Grade A (low-carbon steel, grade C (medium-carbon steel), and grade D (carbon-manganese steel). Manufacturing processes must include heat treatment, welding after cooling. Welding process of ASTM A335 P91 Pipe-Boiler Tubes,Heat ASTM A335 P91 steel pipes have been widely used in the main steam pipes of large power stations in China in recent years because of its good high temperature comprehensive properties. A335 P91 steel is widely used in the construction of many large-scale thermal power plants in recent years. A335 P91 steel is a new martensitic heat-resistant steel developed in the late 1970s and early 1980s in Welded steel pipe,Welding steel pipe,Welded steel tube Main application :Welded steel pipe and welded steel tube mainly used for water transportation,boiler and pressure vessel buildings in industry. Rolling range:Thickness*OD*Length 0.95-30mm*20-1200mm*1000-18000mm. Test:Flattening,Expansion,Hydro and Eddy view testing,heat treatment,Non-destructive examination,Low temperature mpacting test.

My thinking is that the water would provide a heat sink that would cause severe quenching of the weld and cause cracking.

Stainless Welded Tube Used for Heat ExchangerIn addition, as the stainless steel welded pipe process becomes more and more mature, it can gradually replace the stainless steel seamless pipe in many applications, such as:heat exchanger equipment, medium and low pressure boiler tubes and so on. Stainless Steel Welded Pipe Production Features: Socket Weld Pipe Cap Manufacturers - ASME B16.11 Socket weld pipe fittings are manufactured by forging, followed by heat treatment and machining solid steel as per ASME B16.11 and other dimensional standards. For bigger size piping systems buttweld pipe fittings produced as per ASME B16.9 are used.
