Stainless steel flange surface treatment methods

2017-12-23

Stainless steel flange surface treatment methods: According to the complexity of the stainless steel flange and the user request by mechanical polishing, chemical polishing and electrochemical polishing method to achieve the specular gloss. Increasing the flange neck increases the overall stiffness of the flange, reducing the stress on the flange neck and flange. Customers But for those customers who are "lying" or fail to understand the flange standard, it is hard to accurately report the actual price because there is no reference standard. What should be done at this time? Usually, for the first time I quote him, according to the mechanical standards of mechanical flange below the national standard and chemical standard, so the price is low, so customers generally acceptable if he adds a more accurate standard, we will be based on accurate Standard price. In the fully open or fully closed, the ball and valve seat sealing surface and media isolation, the media will not cause erosion of the valve sealing surface.
Stamping welded elbows in the actual production, in accordance with certain processes and production methods and production to ensure the normal use of performance and value, the need to use the normal production standards and process parameters control in the actual production trends have important value and performance
Ultrasonic testing technology is the use of ultrasonic pulse reflection principle of measuring the thickness of the wall after corrosion. But the open area and carbon steel right-angle pipe is good, only consider the cost of carbon steel pipe roasted, cold pipe bending can be carbon steel pipe of course, high cost. For example, the so-called nominal PNO. It is a material, energy-efficient processing method that requires less pressure to bend per minute (less theoretical), less flexing material, and therefore less waste of raw materials, and other equipment that does not require heating.
