Can the top coat of epoxy coal bitumen anti-corrosion bend be used directly for the anti-corrosion of the bend?

tsadmin|2023-02-26T10:01:54+00:0026 2 月, 2023|分类：Uncategorized|标签：anti, corrosion, epoxy|

Epoxy coal bitumen anti-corrosion pipe refers to the anti-corrosion process, the inner wall with 8710 coating, the exterior use of epoxy resin anti-corrosion coating. Can be useful to avoid or slow down the process of transportation and use of chemical or electrochemical reaction in the onset of corrosion of steel pipes.According to China's statistics, the annual domestic bend corrosion direct economic loss of more than 180 billion, when the global annual loss of up to $ 500 billion due to bend corrosion. Epoxy coal asphalt anti-corrosion bend can be useful to avoid or slow down corrosion to extend the service [...]

What‘s the 42CrMo Material?

tsadmin|2023-02-22T02:32:48+00:0022 2 月, 2023|分类：Steel Material|标签：42crmo|

Introduction 42CrMo steel is a Chinese alloy steel, and has high strength and toughness, good hardenability, and no obvious temper brittleness. After quenching and tempering treatment, it has high fatigue limit and resistance to multiple impacts, and good low temperature impact toughness. Applications 42CrMo alloy steel generally used for engineering steel purpose, and for making important parts requiring higher strength and larger size of the quenched section than 35CrMo steel, such as shafts, crankshafts, large gears for locomotive traction, supercharger gears, gearbox gears, engine cylinders, oil drill pipe joints, large load rods and spring clips.
