The corrugated pipe culvert for steel
structure, a corrosion threat, the high-speed road to the roadbed and
culvert destined age cycle demand can not be so high, lack of in-depth
consideration of preventive maintenance, maintenance treatment in
difficult sections should use scale. So below to introduce the main
problems of bellows culvert, processing and product introduction.
1
corrugated pipe culvert needs raw materials necessary to have plastic
is very good, so conducive to the elastic properties and processing of
steel corrugated pipe culvert, and followed after processing to get
higher elasticity and demand strength.
2.,
the raw material is necessary to have tensile strength and fatigue
strength, so completely guarantee the normal performance of elastic
function.
3. to have a strong welding ability, but also satisfied with the requirements required for welding.
4.
elasticity is the main reason for the raw material, because the steel
bellows are often affected by the changes in temperature and time.
5.,
the raw materials needed to meet the needs of corrosion resistance, to
ensure that corrugated steel pipe culvert in the project life and
safety.
The corrugated pipe
culvert has the effect of compensating the pipeline and avoiding the
displacement of the pipe in the heating pipeline. So do a heating
pipeline guarantee derusting work is of corrugated metal pipe culvert
life. The derusting methods of heating pipes are divided into manual
derusting, mechanical derusting and chemical derusting.
