Hydraulic pipe joint surface treatment through three important stages: some sub class the use of product as the market becomes more and more over, the performance of the pipe fittings suppliers using three-pass getting mad, customers on the joint of antirust processing, corrosion prevention, and other rules will become more and more high. The rules of nature which is sales market, is also the joint product development trend and the development trend of long-term evolution. Today we are going to grasp the evolution of the joint surface processing historical moment. Gradually, the stainless steel pipe supplier haven't clear entities in the market. Initially using the traditional carbon steel joint "parkerizing anointed with oil" surface treatment method, by corrosion, and anointed with oil to prevent joint is very initial method, as long as consider some high and intermediate rules do not work to use, this kind of surface treatment is also China's national standard joint use more, such as JB - 988 series of products, which is known as the black connector.
In the future in order to better anti-corrosion, beautiful and easy, non-standard type pipe supplier color zinc plating process, zinc plating color has the following advantages: at least 8 microns of coating, the anticorrosion ability brass tube fitting significantly improve; In device process generally cannot prevent scratches or scratches, and galvanizing layer for carbon steel joint body, is a kind of cathode anticorrosion maintenance, can prevent joint part erosion and damage. But the color of zinc plating process with lots of hexavalent chromium in the long term or short term touch or breathe in dangerous carcinogens. Then to the last link joint development trend. In order to better more resistant to corrosion, then white zinc plated, more beautiful and easy, white zinc corrosion level is the double color zinc, now on the market at present stage is the use of trivalent chromium white zinc joint.
And inspection work shall also include in the system software, in determining the joint without poor at the same time, also need to identify the system software is no poor situation, especially the hazard installation in poor operating conditions. Rules for everyone in gradually joint once finishing first, high pressure hose connector supplier is full consideration on the inside of the pipe is full of very high level of cleanliness rules. It is necessary fittings and pipes were first launched the device, in order to ensure its internal, in the case of thoroughly clean, prevent the material inside cause pollution of the environment. So in order to optimize joint device operation, the practical effect, achieve the optimized device, maintain good mood of all system, suggests that we joint the device once, don't forget to check the finishing.
Before I can start installing hydraulic transition joints check and cleaning, avoid using a problem: the hydraulic connector at the beginning on joint installation work carefully check, can't go up and then immediately. But in the gradual spread regularly check before finishing processing. Main is fully considering the joint may be wrong shipment, and its occurrence 38 tube fitting collision damage in transport. In order to avoid those problems, the installation operation smoothly, welded pipe supplier offer you all-round joint do before device inspection, determine the joint did not appear abnormal situation.
