150# so flange a105

Advantages of carbon steel forged flanges:

High Impact Resistance: Ring stiffness is 1.3 times that of solid wall tubes due to the unique impact strength feature which is significantly improved compared to other solid wall tubes.

Long service life: The pipeline has a service life of more than 50 years under the rated operating temperature and pressure, and has anti-ultraviolet and anti-radiation, so that the product will never fade.

Good corrosion resistance: Except for a few hydrogenation agents, it can withstand the corrosion of various chemical media. The flange has excellent acid resistance, alkali resistance, corrosion resistance, no rust, no corrosion, no breeding of bacteria, no Electrochemical corrosion occurs.

Good thermal insulation: Due to the low thermal conductivity of the material, the thermal conductivity at 20 degrees Celsius is 0.21-0.24W/mk, which is much smaller than that of steel pipes (43-52W/mk) and purple steel pipes (333W/mk), so PP-R pipes have good insulation properties.

Good heat resistance: when the working water temperature is 70 degrees, the softening temperature is 140 degrees.
