Sizes of square pipes have to confirm the values indicated in the table below:

Outside size A, mm	Wall thickness s, mm	Section square, cm2	Weight of 1 m pipe, kg,	Inertia moment, cm4~	Resistance moment, cm3~
Outside size A, mm	Wall thickness s, mm	Section square, cm2	Weight of 1 m pipe, kg,	Ix=Iy	Wx=Wy
50	5	8.57	6.73	28.26	11.3
60	8	15.54	12.20	67.71	22.57
100	8	28.34	22.25	392.65	78.53
120	8	34.74	27.27	715.66	119.28

Steel density 7/85 g/cm3

Pipe static characteristic is calculated for R=1,5 s

4. Bending radius R should no more than 2 s.

5. Pipes are produced:

Random length

Seamless cold-deformed – 1.5-11m;

Fixed length

Seamless cold-deformed – 4.5-11m;

Multiple lengths

Seamless cold-deformed – 1.5-11m with tolerance for every cut 5 mm;

Total length of multiple length pipes can’t be more than upper limit of fixed length pipe. Tolerance for every ratio is 5mm (if other tolerance is not stipulated) and is a part of every ordered ratio.

6.Limit deviations for outside sizes, wall thickness & sides concavity can’t be more than indicated in the table below:

Parameter name	Limit deviation of pipe size depending on the precision of production
Parameter name	normal	high
Outside sizes	+-0.3mm	+-0.25mm
Wall thickness: wall thickness ≤ 3.5mm wall thickness > 3.5mm	± 12.5% ± 12.5%	± 12.5% ± 10.0%
Sides concavity and convexity: Up to 50mm Over 50 to 70mm Over 70	0.5mm 0.75mm 1.0mm	0.5mm 0.5mm 0.8mm
Coiling of square & rectangular pipes	-	According to agreement with the customer
