Spiral pipe material, calculation method of spiral steel pipe theoretical weight

In the face of difficulties and problems in the current market, some spiral steel enterprises to actively analyze the external situation and internal strengths, timely adjustment of development strategy, seek development opportunity in crisis.

The adjustment of industrial structure is undoubtedly good measures to cope with the financial crisis. A group limited company according to the adjustment of the industrial structure of market demand for new projects, to seize the pipe end of the market, to win the development opportunity. Last year 1100000000 yuan investment in the construction of an annual output of 800000 tons of iron project and investment 1000000000 yuan in the construction of 720 large diameter steel pipe production line at the end of 3 and early 5 has started production. See below some spiral steel pipe product information, spiral pipe production using steel class level or is the spiral steel pipe material: GB700-88 Q235A, B, GB1591-88 16Mn, APL; SPEC5L A, B, X42 - X60, GB/T9711.1 - 1997, L210 - L415.

Calculation method of spiral steel pipe theoretical weight:

Angle: weight per meter =0.00785* (edge width + edge width - edge thickness) * edge thickness

Round: weight per meter diameter (=0.00617* diameter * thread steel and round steel the same)

Flat: weight per meter =0.00785* thickness * width

Tubing: weight per meter of wall thickness of =0.02466* * (diameter - thickness)

Plate: weight per meter =7.85* thickness

Brass: weight per meter of wall thickness of =0.02670* * (diameter - thickness)

Copper: weight per meter of wall thickness of =0.02796* * (diameter - thickness)

Aluminum riffled plate: the weight per square metre =2.96* thickness

Nonferrous metal: the proportion of copper plate 8.9 brass 8.5 zinc plate 7.2 plate 11.37.
