ASTM A179 Round Pipes Boiler tubes refers to hollow round section steel that is used in manufacturing heat transfer unite. ASTM A179/ASME SA179 specification is designed as American standard of Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser Tubes. Diameter and wall thickness of ASTM A179/ASME SA179 hollow pipe has a wide range from small diameter to several meters. ASTM A179 hollow round steel pipes can be used for pipeline in thermal equipment, industrial machinery, petroleum geological exploration, container, chemical industry and other special purpose.
ASTM A179 cold drawn carbon steel pipe can generally be soSteelrted into seamless and welded steel pipe (according to manufacture methods) two categories. As to ASTM A179 steel pipe, it is made into seamless steel tubes, as the steel tubes have to work under high temperature and pressure, it has to withstand the pressure to hydraulic experiment to test its voltage capacity and quality, leakage, wet or expansion for qualification, some boiler steel tubes also need requirements for flanging test, the flaring test and flattening test.
ASTM A179 hollow round steel pipe is widely used as water wall tube, high pressure boiler tube, superheated steam tube, smoke pipe with large and small diameters, etc. In general, it is used in high temperature and pressure conditions.
20G seamless steel pipe is one common China steel grade of boilers belonging to GB5301 steel specification. As steel manufacturing technology improves, 20G seamless steel pipe has become one popular steel product for boiler needs.

GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
Bulb flat steel for shipbuilding
The bulb flat steel is a kind of medium section material which is mainly used in the field of shipbuilding and bridge building, and the shipbuilding bulb flat steel is an auxiliary medium section material for shipbuilding.
