Product details
1 Raw materials purchased from Sany original plant Double seamless steel pipe is selected. Double Layer Clearance-Free Composite the inner layer has high wear resistance. Steel pipe total thickness up to 5.5mm Chinese standard high strength 65Mn Steel (Similar to the German standard ST52) the wear resistance of the product has been greatly improved.
2Our factory used advanced automatic welding equipment and flanges of higher quality so the weld is very beautiful and it is not eaay for the head to fall off. Although the production cost has been greatly increased we still insist on using flux-cored electrode and mixed gas for welding. make welding quality much superior to other products on the market.
3Our factory used advanced quenching equipment make the anti-abrasive performance of the product more excellent. The determinants of product quality often lie in details that people often don't notice. Take quenching for example High Frequency Induction Quenching is much better than ordinary quenching this technology can effectively prevent annealing keep the best wear resistance of the product. Inductor for Hardening it's a detail that people often don't notice too. Many manufacturers take a long time to replace new inductors in order to save production costs but we insist on replacing new sensors regularly. In this way the stability of product quality is well guaranteed.
4After a long period of high frequency quenching the product will produce an ultra-strong wear-resistant inner layer up to 3.7mm. So the service life of the product can reach 50000-60000CBM.
5We use the first welding and quenching then add installation flange inner bushings. This method can effectively prevent deformation and annealing during welding and some other manufacturers on the market can easily ignore the problem lead to the occurrence of flange inner sleeve shedding. friends must pay attention to this when choosing and purchasing. Many manufacturers can not do the above details which makes the quality of products very different friends must pay attention to this when choosing and purchasing.
6We are factory specializing in the manufacture and export of concrete pump pipe for more than 22 years. We have profuse designs with series quality grade and expressly Under the same quality our price is very competitive because we are manufactory we are the source. We have a lot of 3m stock other sizes can be customized according to customer requirements welcome friends to come to the procurement.
