Stainless Steel Weld Tee In production, the process and principle are followed, and the geometric dimensions of the tee, including outer diameter, inner diameter, wall thickness, etc., can be well produced in actual use. It is the requirement for packaging. For small pipe fittings, such as export, wooden boxes are required, about 1 cubic meter, and the number of tees in such boxes is stipulated to be no more than one ton. The standard allows sets, that is, large sets of small, but the total weight generally cannot exceed 1 ton. For large pieces, they must be packed individually, such as 24 inch. In addition, there is the packaging mark, which is to indicate the size, steel grade, batch number, and manufacturer's trademark. The tee should be stamped with a steel stamp and accompanied by documents such as a packing list and a warranty. It is also required to control the radius of curvature. For example, if the radius length is 1.5D, then the radius of curvature is within the required tolerance range.

The production process of the tee is basically the same. Cutting should be carried out according to the different specifications of the tee. After cutting, sandblasting should be carried out first, and the surface oxide scale should be removed before forming. The forming is formed by hydraulic bulging method. There is a mold with a flat bottom and a flange hole on the top. After the pipe is placed, the pipe is fixed with a hydraulic cylinder, and the two sides are filled with liquid to bulge inward, squeezing the pipe into a "convex" shape, and then the bulge is cut off from the appropriate position and also made into a groove. It needs to be shot peened twice. Because of work hardening during the processing, heat treatment is also required. The production process of the tee is like this.

Since most of the tees are used for welding, in order to improve the welding quality, the ends are turned into grooves, leaving angles and edges. This requirement is also relatively strict. The thickness of the edge, the angle and the deviation range are all specified. There are many more items in the geometric dimensions than pipe fittings. The surface quality and mechanical properties are basically the same as those of the pipe. In order to facilitate welding, the steel type is the same as that of the connected pipe. That is, all tees must undergo surface treatment, and the iron oxide on the inner and outer surfaces must be sprayed off by shot peening, and then painted. This is not only for export needs, but also for domestic transportation to facilitate rust and oxidation. This work must be done. Before installation, first check whether the quality of pipes, pipe fittings and rubber rings is qualified, and wipe the working surface inside the socket. After sealing, let the pipe fittings dry for 20 minutes to achieve the degree of sealing bonding and achieve the sealing effect. The quality of the pipe fitting rubber ring is unqualified: the rubber ring has pores, cracks, and seams. The rubber ring has too long or too short vulcanization time, resulting in unsatisfactory elasticity of the rubber ring. The pipe fitting system is in place, which is conducive to the experience of people's pipe fittings users, establishes a good pipe fitting damage maintenance system, and the normal operation of civil pipe fittings. The rubber ring is placed in the socket groove in the specified direction (big head facing inward, small head facing outward) and must not be twisted. After installation, carelessness is not used to check with a feeler gauge, resulting in the rubber ring being pushed out of the expansion groove.

The scope of use of pipe fittings is very large, but it is less reflected in my country. If a definition of pipe fittings is given, I think all products produced by deep processing of pipes should belong to the category of pipe fittings. Since pipe fittings are made of pipes as raw materials and become a product through deep processing, this product has the dual characteristics of pipes and mechanical parts, and is a combination of the two. Pipes are the raw materials of pipe fittings, but there are many processing methods for pipe fittings, as long as it is a mechanical processing method, it can be applied.

Different tee pipe fittings have their own advantages and disadvantages, and different tee pipe fittings have different characteristics. The customers of tee pipe fittings are generally facing the oil industry, chemical industry, shipbuilding industry, electricity, construction industry, etc. Distinguish different tee pipe fittings, understand their respective characteristics and shortcomings, then we can use tee pipe fittings.

The tees in the pipeline are divided into mechanical tees, grooved reducing tees, grooved mechanical tees, and ordinary tees. The three-way pipe fitting ball valve produced by Binhai Pipe Fittings can be made into L shape (right angle) or T shape. Any port can be used to connect with the side port to divert the medium flowing in from the side port and enter any port. Different media entering the two ports can also be mixed and flow out from the side port. The same three-way ball valve can be used to control the side system or circulation system, and can also control the flow of fluids in or out from different storage locations.
