Ordinary steel pipes are generally used in machinery or systems that do not have special requirements for steel pipe accuracy and pressure resistance, while hydraulic steel pipes generally require seamless steel pipes with high accuracy and high pressure resistance.
At present, the steel pipes used in hydraulic systems are mainly stainless steel seamless pipes, ordinary seamless pipes, and DIN2391 high-precision hydraulic steel pipes. Although stainless steel seamless pipes have excellent mechanical properties, they have not been widely used due to their high price and low accuracy. Although ordinary seamless steel pipes are commonly used, their mechanical properties are poor and their accuracy is low. Before use, they usually undergo a series of welding, trial assembly, acid washing, alkali washing, water washing, long-term oil flushing, and leakage testing. The process is complex, time-consuming, and unreliable, and the residue inside the pipe is not completely removed, becoming a major hidden danger for the entire hydraulic system to malfunction at any time. According to statistics, 70% of faults in hydraulic systems are caused by this reason.
Reminder: The complex process of using ordinary seamless steel pipes in hydraulic systems has invisibly become a high investment and consumption work, which greatly increases costs for enterprises.
Compared to the above two types of steel pipes, DIN2391 series high-precision precision bright seamless steel pipes are specialized pipes for hydraulic systems. It has the following six major advantages:
※ The inner and outer walls of the steel pipe have no oxide layer and can be directly installed in the hydraulic system for use
※ Withstand high pressure without leakage
※ High precision
※ High smoothness
※ Cold bending without deformation
※ Flaring and flattening without cracks
Comparison:
The process of using ordinary steel pipes:
※ Welding: Welding slag, oxide layer, and possible leakage
※ Pickling: Consumable, time-consuming, labor-intensive, and dangerous
※ Alkali washing: consumables, time consumption, and labor consumption
※ Water washing: waste of resources
Long term oil leakage: power consumption, oil consumption, time consumption, and labor consumption
※ Leakage test: repair welding is required
Conclusion: The entire process is complex and the working hours are long
Using DIN series high-precision black phosphating precision seamless steel pipe process:
Purchase and receive DIN pipes for warehousing, install them on board, and put them into use after installation
Conclusion: Completing tasks in one day is simple, fast, labor saving, time saving, and material saving, which means saving money!
The connecting pipe fittings matched with the DIN series high-precision precision bright seamless steel pipes are ferrule type pipe joints. This type of pipe joint has a simple structure, good performance, small volume, light weight, easy piping operation, easy disassembly, can withstand large vibrations and impacts, and plays a role in preventing loosening. The working pressure is 16-40Mpa, making it an ideal pipeline connection in hydraulic systems
