How is the alloy elbow cleaned?
Alloy elbows are used and implemented in different fields and professions to ensure the safety and non-pollution of water, and are used in different places to play an important role. It has excellent mechanical and physical properties. The strength of the alloy compression tee is very high, which is 2 times of galvanized pipe, 3 times of copper pipe, and 8-10 times of PP-R pipe, and it can be very good at oscillating impact, and it has the characteristics of no leakage, no [...]
3PE anti-corrosion steel pipe heat shrinkable sleeve use
3PE anti-corrosion steel pipe heat shrink sleeve in the mid to late nineties began to be used in the oil and gas industry for long-distance transportation of oil and natural gas steel pipe weld anticorrosion at the beginning of this century and a large number of applications in the long-distance transmission of oil and natural gas steel pipe weld anticorrosion, city gas pipeline network seam anticorrosion, heat supply steel pipe seam anticorrosion, water pipe seam anticorrosion and other fields. This paragraph from the [...]
Can the top coat of epoxy coal bitumen anti-corrosion bend be used directly for the anti-corrosion of the bend?
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 [...]

What‘s the 42CrMo Material?
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, [...]
