La description
Definition: seamless steel pipes have hollow
sections, and are applied to pipes for conveying fluids in
quantity, such as pipes for conveying petroleum, natural gas, coal
gas, water and some solid materials. Compared with round steel and
other solid steel materials, steel pipes have lighter weight at the
same bending and twisting strength, belong to economic section
steel materials, and are widely used for manufacturing structural
parts and mechanical parts, for example, annular parts of oil drill
rods, automobile transmission shafts, bicycle frames, steel
scaffoldings used in building construction and so on are
manufactured by steel pipes, which can improve the material
utilizing rate, simplify manufacturing processes and save materials
and processing time, and have been widely manufactured by steel
pipes.
Packing: bundling, nude packing, or packing
according to customer requirements
Types:
a. Seamless pipe (GB******7) for general structure and mechanical
structure
b. Seamless pipe (GB/T********9) for low and medium-pressure
boiler
c. Seamless pipe ST*5.8/**1 (GB******5) for high-pressure
boiler
d. Seamless pipe (GB/T********9) for conveying fluids
e. Cold-drawn or cold-rolled precision seamless pipe
(GB******3)
f. Geological drilling steel pipe (YB*****0)
g. Oil drilling steel pipe (YB*****5)
h. Seamless pipe (*7SiMn) for hydraulic support
i. Seamless pipe (GB******6) for chemical fertilizer
j. Shipbuilding pipe (GB******5)
k. Oil cracking pipe (GB******8)
l. Various alloy pipes (*6Mn, *7SiMn, *5CrMo, *5CrMo, *0CrMo,
*2Cr1Mov)
Production processes:
a. Main production processes (â–³main inspection processes) of
hot-rolled seamless steel pipes:
Pipe blank preparation and inspection â–³→pipe blank heating
→perforation →pipe rolling →steel pipe reheating →sizing (reducing)
→heat treatment â–³→finished pipe straightening →finishing
→inspection â–³→(lossless, physicochemical, platform frame
inspection) →warehousing
b. Main production processes of hot-rolled (drawn) seamless steel
pipes:
Blank preparation →acid pickling and lubrication →cold rolling
(drawing) →heat treatment →straightening →finishing →inspection
