Superb performance of S-shaped pipe of concrete pump：
①.45MN2 steel is used, with extra resistance to wearing.
②.Overlaying welding with high-performance wearing-resistant electrode applied to interior of tube, which is key to improved service life.
③.Castellated shafts are made of 45 steel, with modification conducted to ensure favorable mechanical properties。
④.Overall welding and assembly use special clamps to ensure high accuracy and convenient installation.
⑤.All S-shaped pipes have long and short nobelium-coated bushing.
Characteristics of S-shaped pipes:
1.Casting materials of S-shaped pipes vary greatly, the commonest 45MN2, 45 and 20 steel. By resistance to wearing, 45MN2 performs the best.
2.The market of wearing-resistant electrodes is complex, and price decides the quality. Use of superb wearing-resistant electrodes can guarantee the service life of S-shaped pipe.
3.Castellated shafts of pipes generally need complex heat treatment, or they break easily during high-intensity pumping.
4.Installation of S-shaped pipes is labor-consuming. Space between hopper and S-shaped pipe is small, and the absence of special clamps during assembly of S-shaped pipes will result in big dimensional error which in turn causes difficult installation or failed installation.
