Seamless carbon steel tee fittings

Carbon steel tee fittings are generally used for regulating valve devices and are used for draining. Concentric reducers are beneficial to fluid activities and have less interference with fluid flow regimes during variable diameters.
 
The seamless tee thus uses a concentric reducer to reduce the diameter of the liquid and straight liquid tubes. Because the one side is flat, it is good for exhausting or draining, which is convenient for driving and overhauling. Therefore, the liquid pipeline of the horizontal device generally uses a partial-diameter reducer.
 
The reducer is also called the size head. The diameters of the two nozzles are different. They are used to connect pipes or flanges of different diameters for diameter reduction. The two ends of the concentric reducer, the center of the circle on the same axis, the time of the variable diameter, the tube orientation is calculated by the axis, the orientation of the tube is constant, and is generally used for gas or straight liquid pipe diameter reduction. The two ends of the partial-reducing reducer are internally cut, generally used for horizontal liquid pipes.
 
Butt welding tee is a steel hot press forming or forging forming elbow. Its connection method is to directly weld the tee and the steel pipe. The main production standards of the butt welding tee are generally GB/T12459, GB/T13401. , ASME B16.9, SH3408, SH3409, HG/T21635, HG/T21631, SY/T0510.
 
Butt welding tees generally have equal-diameter tees, different-diameter tees, etc. The materials are carbon steel, alloy steel and stainless steel.
 
Carbon steel tee when the chromium content in the steel reaches about 1.2%, the action of chromium in the corrosive medium forms a thin oxide film (self-passivation film) on the steel surface, and the seamless tee can prevent the steel. The substrate is further corroded. In addition to chromium, commonly used alloying elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses for concentric and different diameter pipe arrangement and performance. When the diameter pipe is produced, it adopts certain production and processing techniques to ensure good performance and performance in production and processing.
 
Concentric reducers are resistant to weak corrosive media such as air, steam, water, and corrosive metals such as acids, alkalis, and salts. In practice, corrosion resistant materials are often corroded.
