Product Description

Product Usage

Q361F PN1.6-PN2.5 all-welded ball valve is widely used in various fields, its superior quality and high-performance stability is not common cast steel ball valve, all-welded ball valve life is far greater than the cast steel Ball valves, all-welded ball valves are widely used in urban gas, urban heating, petrochemical, shipbuilding, steel, pressure regulating stations, power plants and other types of pipeline equipment.

 

Features

1. All-welded ball valve, there will be no external leakage and so on. Sphere processing has advanced computer detector tracking test, so the ball of high precision machining.

2. As the valve body material with the same pipe material, there will be no uneven stress, it will not be due to earthquakes and vehicles through the ground when the deformation, the pipeline anti-aging.

3. The sealing ring body is made of RPTFE with 25% carbon content to ensure no leakage (0%) at all.

 

skills requirement

1, design and manufacture according to the provisions of API 6D.

2, the valve inspection and testing in accordance with the provisions of API 598.

3, the length of the valve structure according to the provisions of GB / T12224-2005.

4, the connection size according to the provisions of GB / T12224-2005.

5, pressure - temperature benchmark according to the provisions of ASME B16.34.

6, the valve mark according to the provisions of GB / T12220.

7, the valve sulfur by NACE MR 0175 requirements.
