Tubing fittings are divided into five types by appearance:
(a) Thickening, not thickening, short sections - Same specifications at both ends, one end of a short pipe connected to the thickened pipe, and the other end not connected to a thickened pipe or special threaded pipe;


(b) Conical sections with a larger outer diameter - different specifications at both ends, one short tube connected to a large outer thick oil tube, and the other end connected to a small size tube;


(c) Thicker outer thickened short sections - Same specifications at both ends, one short pipe connected to the outer thick oil pipe and the other end connected to the same size thick oil pipe;


(d) Short sections of the same diameter - same specifications at both ends, short joints at one end of the tube are not thickened or specially threaded, and the other end is not connected to thickened or specially threaded tubes;


(e) Non-thickened tapered ends - different specifications at both ends, one end of the fitting is connected to the large non-thickened tube and the other end is connected to the small size tube.


Tubing fittings are divided into three types by function:
(a) Male and female short sections: Both ends are male threads, no thickening and short section thickening, thick and short section, thick and thick short section, the same diameter short section, and no thick cone joints.


(b) Pitch transition: One end of the male thread, the other end of the female thread, the thickening of the outer short section, the short section of the thickening of the outer thick part, and the short joint that is not thickened to adjust the tightening on the coupling. on.


(c) Adjustment of short section: Indefinite length, designed according to engineering requirements, one end is male thread, the other end is thickened by female thread, thickened in short section, thickened in shortened section, thickened in thickened short section, TH. Tighten short sections of the same diameter short section and non-thick section on the joint.
