description:
1.with reference to pre galvanized steel pipe, before the zinc
repair in the welding, we will first set out to remove the welding
slag, zinc oxide skin and burned out layer. Then we use the spray
painting for the repair of the zinc layer. We have the zinc repair in
the welding close to the whole weld body in color, as a result of
little color difference. Our finished galvanized pipe looks like much
nature itself without blemish .
2.we can produce different types of steel pipes and the length is
controllable. Besides, we have advanced technology and equipment
controlled by computer, which can customize the length of steel pipes
according to the customers' requirements. In terms of galvanized
steel pipes, the length we can produce is ranging from 3 to 16 meter
while the length of black steel pipes is from 4.5 to 16 meter. The
common lengths for galvanized steel pipe are 3.05m, 3.75m, 5.8m,12m,
7.3m,6m etc. As to black steel pipe, the common lengths are
4.5m,5.8m,6,9,12 etc. Generally speaking, allowable length tolerance
is about 0-20mm using fixed length saw. The tolerance can be
controlled under 5mm with the process of second saw cutting. Notably,
the tolerance is even around ±1mm through the tool of small saw with
below 100mm diameter.
