Large-diameter butt-welded tee pipeline steel L290 ASME 36" SchXS
Precautions for purchasing L290 pipeline steel tee
1. First determine whether the controlled medium is oil or water.
2. Calculate the flow m³/h of the controlled medium, and select the caliber of the three-way thermostat according to the controlled medium and its design flow.
3. According to the valve body material (cast copper or T cast iron), connection form (F flange, G pipe thread, ZG taper pipe thread), valve structure type (Z rotary valve type, H slide valve type), temperature adjustment range and The installation type determines the model of the three-way control valve.
4. According to the different flow directions of the three valve ports, the three-way thermostatic valve can be used for merging or splitting control occasions.
5. The function of the confluent three-way thermostat valve is to mix two fluids with different temperatures through the valve into a third temperature fluid with a temperature between the first two. This valve has two and one outlets. The temperature element is installed at the exit. The function of the split three-way thermostat valve is to divide a fluid into two proportionally after passing through the valve. When the valve closes one outlet, it opens the other outlet. This kind of valve has one inlet and two outlets.
6. The three-way thermostat valve can replace a two-way valve and a three-way pipe.
7. The rotary valve type three-way thermostat has six installation types, which are suitable for the connection of any pipe direction. The installation type is selected according to the actual pipe connection of the system.
8. The three-way temperature control valve can be installed at any position, but the emergency manual device surface should be installed in a position that is convenient for operation.
9. In order to prevent the impurity in the medium from jamming or clogging, the three-way temperature regulating valve should be equipped with a filter before the valve.
L290 pipeline steel tees are divided into equal diameter tees and reducing tees
L290 pipeline steel tee welding tee is generally divided into equal diameter tee, reducing tee, and the materials are carbon steel, alloy steel and stainless steel. Welding tee is a section of main pipe plus a small branch pipe. Obviously, the two larger sizes are main pipes, and the smaller one out of them is the branch pipe. In pure oxygen pipelines, there is usually pressure, and the oxygen is active at this time. Larger; if a welding tee is used, as long as the debris in the tube moves with the oxygen flow, the change in the flow rate due to the change of the pipe diameter may cause the debris to collide with the tube, or the static discharge caused by the change in the flow rate. All may cause the pure oxygen tube to catch fire. Welding tees are widely used in industrial pipelines such as petroleum, aerospace pharmaceutical, chemical, metallurgical, and power engineering supporting facilities. There are two types of production processes: one is seamless cold drawn tee, and the other is seam welded tee. Welding tee material: carbon steel, stainless steel, alloy steel, duplex steel, nickel-based alloy,;
Welding tee caliber 3/4"-80"; executive standard: ASME/GB/T12459-2005GB/T13401-2005GB/T10752-1995GB/T14383-93HGJ514-87DL/T695-1999D-GD0418 welding tee production port pressure: SCH10 , 20, 30, 40, 60, 80, XS, XXS, 160.
