Seamless Carbon Steel Pipe St37
Welded steel pipe, also known as welded pipe, is made of steel
plate or strip after crimping forming welded steel pipe, general
length 6 meters. Welded steel pipe production process is simple, high production
efficiency, variety of specifications, less investment in
equipment, but the general strength is lower than seamless stee
Since the 1930s, with the rapid development of high quality strip
rolling production and the progress of welding and inspection
technology, the quality of weld is constantly improving, the
variety and specifications of welded steel pipe are increasing day
by day, and replaced seamless steel pipe in more and more fields. Welded steel pipe is divided into straight seam welded pipe and
spiral welded pipe according to the form of weld. Classification by production method: Process classification - arc
welding pipe, resistance welding pipe, (high frequency, low
frequency) gas welding pipe, furnace welding pipe.
Direct seam welding is used for smaller diameter welded pipes,
while spiral welding is used for larger diameter welded pipes. According to the shape of the steel pipe end, it is divided into
circular welded pipe and special-shaped (square, rectangular, etc.)
welded pipe; According to the different materials and uses, it can be divided
into welding steel pipe for mineral fluid transportation,
galvanized steel pipe for low pressure fluid transportation,
electric welding steel pipe for belt conveyor roller, etc. According to the current gb specification size table, according to
the outer diameter * wall thickness from small to large order.
Product standards
The common materials of welded pipe are: Q235A, Q235C, Q235B, 16Mn,
20#, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17,
00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb and so on.
The blank used for welding steel pipe is steel plate or strip
steel, which is divided into furnace welding pipe, electric welding
(resistance welding) pipe and automatic arc welding pipe because of
the different welding process. Because of its different welding form is divided into straight seam
welding pipe and spiral welding pipe two kinds. Because of its end shape is divided into circular welded pipe and
shaped (square, flat, etc.) welded pipe. The welded pipe is divided into several varieties as follows
because of its different materials and uses:
GB/T3091-2008 (welded steel pipe for low pressure fluid
transportation) : mainly used for conveying water, gas, air, oil,
heating hot water or steam and other general low pressure fluids
and other purposes. Its representative material is: Q235A steel.
GB/T14291-2006 (welded steel pipe for mineral fluid transportation)
: mainly used for straight seam welded steel pipe for mine air
pressure, drainage and shaft gas discharge. Its representative material Q235A, B grade steel.
GB/T12770-2002 (welded stainless steel pipe for mechanical
structure) : mainly used in machinery, automobile, bicycle,
furniture, hotel and restaurant decoration and other mechanical
parts and structural parts. Its representative material 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9,
0Cr18Ni11Nb and so on.
GB/T12771-1991 (welded stainless steel pipe for fluid
transportation) : mainly used for conveying low-pressure corrosive
media. The materials are 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb,
0017Cr17Ni14Mo2, etc.
In addition, welded stainless steel pipe for decoration (GB/T
18705-2002), welded stainless steel pipe for architectural
decoration (JG/T 3030-1995), and welded steel pipe for heat
exchanger (YB4103-2000).
