DIN 17175 Grade ST35.8 / EN 10216 – 2 Grade P235 GH TC 1 and TC 2 Seamless Carbon Steel Pipe
DIN 17175 ST 35.8 is a seamless non-alloy steel pipe with a tensile strength of 360 – 480 MPa and a yield strength of 235 MPa minimum at wall thickness of ≤16 mm, commonly used in boilers, pipelines, pressure vessels and other high-temperature and high-pressure environments with a maximum operating temperature of up to 600℃. The steel number is 1.0305.
DIN 17175 St35.8 permits the supply of tubes in both quality I and quality III.
Equivalent with EN 10216 – 2 / Grade P235 GH TC 1 and TC 2.
DIN 17175 Grade 13 CrMo 4-5 Seamless Carbon Steel Pipes
DIN 17175 is the specification for a heat-resisting seamless steel tube. Grade 13CrMo4-5 alloy steel tube is used in the heating surface pipe with low and medium pressure boilers, in which operating pressure is generally not greater than 5.88mpa and the operating temperature is below 450℃. The addition of Ni and Cr element makes 13CrMo4-5 alloy steel tube with high mechanical performance and corrosion resistance, which is used for heating surface pipes, coal economizers, superheaters, reheaters, petrochemical industry pipes and so on in high-pressure boilers (working pressure is generally above 9.8 Mpa and the working temperature is between 450℃ and 650℃).
JIS G3461 Grade STB 340 Seamless Carbon Steel Tubes
JIS G 3461 STB340 is a Japanese specification of seamless and electric resistance welding (ERW) carbon steel tubes with a minimum tensile strength of 340 MPa and a minimum yield strength of 175 MPa for boilers and heat exchangers.
JIS G3461 Grade STB 340 Carbon Steel Seamless Tubes are also known as mild steel pipes and tubes.JIS G3461 Grade STB 340 Tubes are low-cost Low Carbon Steel Tubes with max 018 % carbon content with combination of 030-060 % manganese easy to form and shape .These pipes are manufactured as per JIS Specification and commercially referred as cs pipes or ms pipes.Low Carbon Steel Pipes are not as hard as hig carbon steel pipes,Though carburizing can increase its surface hardness.
ASTM A192/ASME SA192
ASTM A192, identical with ASME SA-192, is the standard specification covering minimum-wall-thickness seamless carbon steel boiler and superheater tubes for high pressure service. The tubing sizes and thicknesses usually furnished to ASTM A192 are 1/2″ to 7″ [12.7 mm to 177.8 mm] outside diameter and 0.085″ to 1.000″ [2.2 mm to 25.4 mm], inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.
ASTM A210 / ASME SA 210 M A1
ASTM A210 / A210M Standard covers minimum-wall thickness, seamless medium-carbon steel, boiler tubes and boiler flues, including safe ends, arch and stay tubes, and superheater tubes.
ASTM A210 / A210M tubing sizes and thicknesses usually furnished to this specification are 1⁄2 in. to 5 in. [12.7 to 127 mm] in outside diameter and 0.035 to 0.500 in. [0.9 to 12.7 mm], inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.
ASTM A210 / A210M Mechanical property requirements do not apply to tubing smaller than 1⁄8 in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.
BS 3059 Grade 320 ERW Carbon Steel Boiler Tubes
Mild steel pipes and tubes are another name for BS 3059-1 Grade 320 Carbon Steel ERW Tubes. BS 3059-1 Grade 320 ERW Tubes are low-cost Low Carbon Steel Tubes with a maximum carbon content of 0.16 percent and a manganese content of between 0.3 and 0.7 percent. They are easy to shape and form. These pipes are made to BS Specification and are called CS Pipes or MS Pipes in the business world. Big carbon steel pipes are harder than low-carbon steel pipes, but the surface of a low-carbon steel pipe can be made harder by carburizing it.
