Hebei Industry Chiho large welded flange connections easy to use, able to withstand greater pressure in the pipeline industry, the use of a wide range of flange connection in the family steel flange, small pipe diameter, and low pressure, Invisible flange connection. If a boiler room or production site steel flanges, everywhere flanged pipe and equipment. welding neck collar with loose flange screw connection points (wire tapping) flange and welding flanges low pressure small diameter wire flange, high pressure and low pressure large diameter are using welding flange thickness and bolt diameter and the number of different connection flange pressures are different. large welded flange product technology standards and quality control: Feed - physics and chemistry - cutting - hot forged - heat treatment - test - metal processing - product testing - Identification - product testing - Identification - Packaging type - shipping the first half of the domestic plate market prices will continue at low levels. adjust supply and demand in the second half of the stage with ease steel flange Click image processing, prices will continue to show volatility trend adjustment forging steel flanges, the price could be higher than the first half. International welded flange anti-corrosion, acid, long service life, reasonable prices, smooth, acid and alkali, high temperature, reasonable prices, good appearance, texture and strong performance.
