This news is mainly about the main imports and exports of high-pressure boiler of SMLS pipe.
(1) Seamless steel pipes for high-pressure boilers are mainly imported from Japan and Germany. Frequently imported specifications are 159.1*4.2mm, 273*4.0mm, 219.1*10.0mm, 419*7.5mm, 406.4*6.0mm, etc.
. The minimum specification is 31.8*4.5mm, and the length is generally 5 to 8m.
(2) In cases of import claim, it was found that by the ultrasonic flaw detection of ST45 seamless boiler pipe imported by Mannesmann steel pipe plant in Germany, a small number of the internal defects of steel pipes exceeded the regulations of the plant and Standards of German Iron and Steel Association.
(3) Alloy steel pipes imported from Germany are mainly 34CrMo4, 12CrMoV, etc. This kind of steel pipe is in good high temperature performance and is often used for high temperature boiler.
(4) There are many alloy pipes imported from Japan, with specifications of 426.0*12mm*5-8m, 152.4*8.0mm*12m, 89.1*10.0mm*6m, 101.6*10.0mm*12m, 114.3*8.0mm*6m, 127.0*8.0mm*9m, etc. Steel grade of JISG3458 under Japanese Industurial Standard is STPA25. This kind of steel pipe is often used for high temperature alloy pipe.
