Abstract
The utility model provides a main pipe and branch pipe connecting structure for a piping component. The lateral surface of the main pipe is provided with a cylindrical stretching edge. A plane-type ring welding line is formed at the welding position of the end face of the stretching edge and the end face of a branch pipe. The structure is used for the connection position of the pressure piping component or a pressure container, is convenient to weld and is easy to realize mechanical operation. The production efficiency is greatly improved. The welding quality is ensured. The welding line is uniform and smooth. The corrosion resistance is high. The qualification rate and the service life of a product can be effectively improved.
Description
Technical field
The utility model relates to a kind of by the pipe piece of being responsible for and arm constitutes, and particularly pipe piece is responsible for and a pipe connecting structure.
Background technique
Usually be made of the arm of being responsible for (cylindrical shell) and person in charge side as pressure piping spare or pressurized container parts, both are integrally welded, and its weld seam is for being responsible for and the crossing intersecting line that forms of arm.This intersecting line is a space curve, and especially when the person in charge did not wait with the arm diameter, this intersecting line was more complicated.Above welded structure is difficult to realize automation mechanized operation that generally rely on manual welding, not only manufacturing efficiency is low, also is difficult to guarantee welding quality, and then influences manufacture cost, product qualified rate and the working life of product.
The model utility content
The purpose of this utility model be to provide a kind of easy to process, manufacturing efficiency is high, can improve the pipe piece in product percent of pass and working life and be responsible for and a pipe connecting structure.
The technical solution of the utility model is: pipe piece is responsible for and is propped up in the pipe connecting structure, the arm end face is integrally welded with person in charge side, its improvements are to be responsible for the welding part, side to be provided with tubular stretching limit, and the weld of stretching limit end face and arm end face is a plane type annulus weld seam.
Described stretching limit is consistent with the arm diameter.
The utility model adds man-hour, the connection part that adopts concavo-convex mould will be responsible for the side on oil hydraulic press is drawn into a stretching cylindraceous limit earlier, and this stretching limit height is decided according to predominant tube diameter and wall thickness size, is generally 10～50mm, handle for neat mouthful the end, welds mutually with arm again.Because this weld seam is a plane type annulus weld seam, wants standard much simple than the intersecting line of pipe fitting, welding is easy to, can realize automation mechanized operation, enhance productivity greatly, and welding quality guarantees easily, even weld is smooth, and good corrosion resistance can effectively improve product percent of pass and working life.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
As shown in the figure, there is cylindric stretching limit 3 person in charge 1 side, and the end face on stretching limit welds mutually with the end face of arm 2, and weld seam 4 is a plane type annulus weld seam, in this example, and stretching limit and arm equal diameters.
Claims (2)
1. a pipe piece is responsible for and a pipe connecting structure, and the arm end face is integrally welded with person in charge side, it is characterized in that being responsible for the welding part, side and is provided with tubular stretching limit, and the weld of stretching limit end face and arm end face is a plane type annulus weld seam.
2. pipe piece according to claim 1 is responsible for and a pipe connecting structure, it is characterized in that described stretching limit is consistent with the arm diameter.
