What is the difference between GBT3087 and GBT8163

 GBT3087--2008 Standard for seamless steel pipes for low and medium pressure boilers, suitable for high-quality carbon structure for low and medium pressure boiler superheated steam pipes, boiling water pipes and superheated steam pipes, large smoke pipes, small smoke pipes and arch brick pipes for locomotive boilers Steel hot-rolled and cold-drawn seamless tubes.

GBT8163--2008 Standard for seamless steel pipes for conveying fluids, suitable for general seamless steel pipes for conveying fluids, 10# and 20# steels in GBT8163--2008 are limited to boilers with rated outlet hot water temperature lower than 120 degrees, heat transfer oil The operating temperature range is generally 200-400 degrees

For long-term circulation in a high temperature environment, the GBT3087--2008 standard should be used, and the temperature of the heat transfer oil in the organic heat carrier boiler is generally 300-400 degrees, so the GBT3087--2008 pipe must be used

What are the surface treatments of EN 10294-1 E355+N seamless pipes

  EN 10294-1 Grade E355+N mild steel seamless pipes are available in thicknesses ranging from 3mm to 100mm, outer diameters from 8mm to 250mm and inner diameters from 5mm to 700+mm. The shape of the pipe can be produced into a round pipe, and it can be produced into a square pipe or other special-shaped pipe by extrusion or welding. The surface finish can also be processed by cold drawing, centerless grinding, hot rolling, smooth turning and peeling. Chemical Properties Carbon Silicon Manganese Phosphorous Sulphur Molybdenum Nickel Chromium Copper Others max 0.22 max 0.50 max 1.50 0.045 0.05 max 0.08 max 0.40 max 0.30 max 0.30 V max 0.10 Mechanical Properties Yield Strength Tensile Strength Elongation A5 min MPa min ksi min MPa min MPa min ksi min Percentage     490 – – 20 E355+N pipe material also belongs to a category of CS pipes, and its hardness is not as good as that of high carbon steel, but its surface hardness can be adjusted by carburizing. The E355 grade is equi...

What are the usual pipes for Power Generation Boiler?

  Power Generation Boiler consists of economizer, furnace (evaporator), superheater tube, reheater tube, main steam tube, and reheater. We can supply all the tubing Power Generation Boiler uses. We also produce pipes of various standards and materials to adapt to the development of the boiler industry: Grade Compositions Applicabie Standards (abbreviation) ASTM EN DIN JIS Carbon steel 0.15-0.25C A53-GR A/B A106-GR A/B A178-GR A/C A192 A210-GR A-1   St45 St45.4 St45.8 C22 STB340(STB35) STB410(STB42) STB510(STB52) STPT370(STPT38) STPT410(STPT42) 0.25-0.35C A106-GR C A210-GR C   St55 St55.4 STPT480(STPT49) Low alloy steel 0.3-0.5Mo T1/T1a P1   15Mo3 16Mo5 STBA12/13 STPA12 0.5Cr-0.5Mo-v     14MoV63   0.5Cr-0.5Mo T2 P2     STBA20 STPA20 1Cr-0.5Mo T12 P12   13CrMo44 STBA22 STPA22 2.25Cr-1Mo T22 P22   10CrMo910 STBA24 STPA24 High chrome ferritic steel 9Cr-1Mo T9 P9   X12CrMo91 STBA26 STPA26 9Cr-1Mo-V-Nb T91 P91   X10CrMoVNb9-1 KA...

What are the applications of steel pipes in the automobile manufacturing industry?

图片
Cars are the daily necessary means of transportation for the public. The manufacture of cars is inseparable from steel pipe products. Let us take a look at the parts of the car that are composed of steel pipes: CCB pipe fittings CCB is mainly used to support man-machine interface control equipment and decorative parts, and at the same time form a safety system with other safety structures. The structure is simple and mainly includes a pipe beam, a side end support, a pipe column fixing support assembly, a lower support leg and an auxiliary support. Seat post It acts as a support structure within the car seat cover, allowing the seat to retain its structural shape. Trunk hinge The trunk hinge is the connecting mechanism of the trunk door of the car. Due to the opening angle of the trunk door, the hinge needs to bear the weight of the trunk door, so the hinge also needs to play a supporting role. Door anti-collision tube When the side door is hit, the sturdy high-strength anti-collision ...
