Those
pipes, which does not meet the rigid requirements of the intended
specification due to some chemical or physical flaw are known as
structural pipe. Structural steel pipes and tubes are those which can be
knocked-down and are then bolted together at the site, where it is to be
used. These pipes are generally used where plant-fabricated pipe cannot
be installed, are not big enough or do not have the strength to support
the loads imposed on them.
Structural steel tubes come in various shapes with circular, square and
rectangular cross-sections and are used for drainage pipe, small bridges
or numerous other construction or industrial applications. The
application ranges from culverts, sub-drains, sewers, service tunnels,
etc. Structural Steel pipe and tubes governs the chemical and mechanical
properties of structural steels and are also used for general
construction and engineering purposes.
The selection of the proper grade (type and strength level) is
important for a particular application. Due to their low weight,
structural pipes offer better resistance to torsional stresses and
sagging. Easy to erect, with simple welded joints, their comparatively
small exterior surface area, without sharp angles or burrs, ensures ease
of maintenance and protection against corrosion.
