Pipe
Galvanizing can increase the corrosion resistance of steel pipe and
prolong its service life.Galvanized pipe USES is very wide, in
addition to a general low pressure fluid such as water, gas, oil
line pipe, also used as oil industry, especially the ocean oil
field oil well pipe, oil pipe, chemical coking equipment of oil
heater, the condensing, exchange of coal distillation wash oil
cooler for tube, and trestle pile, mining tunnel supporting frame
tube, etc.Hot dip galvanizing has the advantages of uniform
coating, strong adhesion and long service life.The complex physical
and chemical reactions between the matrix of hot dip galvanized
steel tube and the molten bath result in the formation of a tight
and corrosion-resistant zinc-ferroalloy layer.
Hot dip galvanized steel pipe is widely used in construction,
machinery, coal mine, chemical industry, electric power, railway
vehicles, automobile industry, roads, Bridges, containers, sports
facilities, agricultural machinery, petroleum machinery,
prospecting machinery and other manufacturing industries.Astm a53
standard The dimensionless designators NPS (nominal pipe size)
[DN(diameter nominal)] have been substituted in this
specifification for such traditional terms as “nominal diameter,”
“size,” and “nominal size.”The term nominal wall thickness has been
assigned for the purpose of convenient designation, existing in
name only, and is used to distinguish it from the actual wall
thickness, which may vary over or under the nominal wall thickness.
