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.
