Aak Hydraulic Valve Has No Red Rust In 1500 Hours Salt Spray Test - Chinaprice: 100.00 Dollar US$
Erdmann has been a purchaser of German HAWE company for 5 or 6 years and has been doing very well.
Last month, the company had a special hydraulic threaded cartridge valve to purchase.
Because it is to be used in the Arctic region, the corrosion resistance of hydraulic threaded cartridge valve needs to be very high.
The boss asked him to identify the suppliers and approve the samples within 2 months.
Erdmann felt that it could be completed within 20 days.
He sent the drawings of hydraulic threaded cartridge valves to the original hydraulic valve manufacturers.
Only 2 weeks later, he received samples of hydraulic threaded cartridge valves from one factory.
The surface gloss of these samples of hydraulic threaded cartridge valves was quite good.
The company tested them on the exploration drilling machine and delivered it quickly to the customer.
3 months later, the customer complained that the hydraulic threaded cartridge valve on the hydraulic pump was seriously corroded, some threads were stuck, the equipment could not be started, and the test run was unsuccessful.
The boss thought that Erdmann was careless and ignored the use scene of the Arctic region.
The boss again asked him to make new samples and do salt spray test inside the company.
Actually, Erdmann emphasized that the hydraulic threaded cartridge valve is to be used in the Arctic region.
The original supplier said that their hydraulic threaded cartridge valves have good gloss and corrosion resistance, and can be used in the Arctic region.
Erdmann communicated with the original hydraulic threaded cartridge valve supplier again, and the reply was that most hydraulic valve manufacturers just adopt the zinc plating process, and he used the nickel plating process which is the highest level of corrosion resistance.
Erdmann realized the difficulty of corrosion resistance in the Arctic regions.
Erdmann emailed more than 20 hydraulic valve manufacturers who had been contacted before, emphasizing that the hydraulic threaded cartridge valve must be in the highly corrosive environment in the Arctic region, and the service life shall not be less than 9 months.
Only 3 hydraulic valve manufacturers said they could have a try, but there was no response from other manufacturers.
Erdmann was a little flustered.
Erdmann saw AAK hydraulic valve on Google, who supplied to hydraulic pump company in Russia.
He felt that AAK might give him a glimmer of hope.
He emailed us to ask if we can produce hydraulic threaded cartridge valves to be used in Arctic regions.
We directly replied that the components of the valve should be treated by special electroplating process in order to meet the condition in the Arctic regions.
After 20 days, AAK sent samples according to his hydraulic threaded cartridge valve drawings.
HAWE company conducted salt spray test on samples from all 4 manufacturers, with the corrosion condition twice that of Arctic regions.
More than 2 months later, Erdmann informed us that AAK hydraulic threaded cartridge valve had no red rust after more than 1500 hours of salt spray test.
At the same time, the company's engineers determined that AAK hydraulic threaded cartridge valve had no problem to be used in the Arctic regions for 1 year.
While the samples from other manufacturers began to produce red rust in more than 120 hours, and there were white corrosion products on the coating surface.
Erdmann hesitated to report to his boss because the quotation of AAK hydraulic threaded cartridge valve is 30% higher than that of other suppliers.
The surface electroplating process of AAK hydraulic threaded cartridge valve is zinc nickel alloy coating, which has high requirements for steel heat treatment.
It may be difficult to find a second factory in Ningbo who can go through both of these two processes smoothly.
In addition, the process cost is more than 5 times higher, but the corrosion resistance is more than 10 times higher than the general zinc plating and nickel plating process.
With these data, the communicated between Erdmann with the boss is very efficient.
The boss mentioned that for all those valves with high standard and high working conditions, just to choose AAK hydraulic valves.
AAK hydraulic threaded cartridge valve will not corrode in the Arctic regions even after being used for 1 year.
