Three links

The three links in the pipeline are divided into mechanical three-way, three-way groove reduction, three-way mechanical groove, ordinary three-way; three-way production method can be divided into top three-way system, suppress three links, forging three links , Welded three links, casting three links and so on. The three links are divided into two types according to the shape: equal-diameter three-way and different-diameter three-way.

Reducing the tee is a section of the supervisor plus a small branch pipe. Obviously, the two big sizes are the supervisors, and the small size indirectly is the branch pipe. In pure oxygen pipelines, there is usually pressure. At this time, the oxygen activity is greater. If a three-way reducer is used, as long as the debris in the pipe moves along with the oxygen flow, the flow rate may change due to changes in the pipe diameter. Collisions with the pipes and the production of fire or electrostatic discharges due to changes in the flow rate may cause the pure oxygen pipes to catch fire.

The equal-diameter three-way pipe is the small pipe diameter at the end of the three-port equal-sized three-way pipe with the same diameter at the two ends of the three-way pipe. The connection for the small pipe branch pipe can be divided into square edge, Round edges and boundless. The surface of the three-way and different-diameter three-way pipe fittings is divided into three categories: hot-dip galvanizing, electro-galvanizing, and baking galvanizing, and a black product three-way.

Three links products have different diameter three links 130R, oblique three links, Y type three links 165, groove type three links, mechanical three links, equal diameter three links and other three links products, specifications from 1/2-6 range, With good mechanical properties, uniform surface gloss, precise geometry, strong rust resistance, interchangeability, quick and easy installation, long service life, environmental protection, and 100% recovery.

Reducing joints and reducing tee are generally standard parts. The outer diameters are I series and II series. If the nominal size is DN150x100, the outer diameter is I series, the wall thickness is Sch20, and the material is 20# concentric reducer. Marked as DN150X100I-Sch20-20 R(C)GB/T12459. Butt welding three links according to GB/T12459 logo, such as DN100X100X80. Socket weld three links according to GB/T14383 logo, such as DN20X15.
