Cold Rolled Precision Hot Rolled Precision Alloy Steel Tube
Seamless Steel Pipe Coating Type Fbe, 2PE, 3PE, 3PP
SHANDONG TONGMAO SPECIAL STEEL CO., LTD combined production , trade
, the development of new products and services together , is one of
the provincial large-scale iron and steel enterprises . Factory
products standards are qualified to meet ISO / GB / ASTM / EN / BS
/ JIS etc . Our company mainly sells steel plate and coil plate ,
has our own large warehouse , annual inventory of more than 10000
tons , of which more than 5000 tons of steel pipe .
Precision steel pipe is a kind of high precision steel pipe
material after cold drawing or cold rolling . Our company currently
has 6 cold-rolled production lines , the main production diameter
of 20-127 mm cold-rolled seamless steel pipe , 2 three-roll mill ,
automatic control system has reached the advanced level in China ,
wall thickness 1-20mm , diameter accuracy 100% , wall thickness accuracy can be done ±0.02-0.1mm , and can
be in accordance with customer requirements of any cutting length .
Precision seamless steel tubes with the traditional electric
furnace + forging or forging billets and rolling. Product
appearance bar, square, forgings. Turbine plant and then for
further processing, but the process is more special, after
processing the metal utilization rate of about 30%. After extrusion
production mode, will have the following advantages:
1, precision hot-rolled seamless steel pipe in the best stress
state, reducing the internal defects.
2, easy to achieve cross-section morphology diversity, adapt to
varieties, small batch production.
3, in every direction of the performance uniformity.
The main method of production extrusion process: electric furnace +
electric furnace> forging or rolling - induction heating>
extrusion - annealing.
Squeeze forging, rolling method is the difference:
1, precision seamless extrusion heating temperature than forging,
rolling high 30-60 ℃;
2, deformation, high-speed (rebar, only 2-4s).
3, multi-step, high consumption of metal.
