Description

The utility model is intended for pipe connections intended for a guaranteed and long-term 25-50-year operational period of use when aggressive and / or fluid flowing liquids belonging to the housing and communal services and / or industrial enterprises are supplied through them.

Known tees of pipeline connections in accordance with GOST 17376-2001 with technological requirements in accordance with GOST 17380-2001 - / 1 /, do not have the technological perfection of their use in quality and short period of their use, and along with the known device according to patent 20360 - / 2 / they also do not due to design features, they can effectively serve in the transportation of liquid media, due to underemovable burr, damage to valves and the short service life of welded joints.

The disadvantages of the analogue / 1 / include the shorter service life of the joints of tees and pipelines in known compounds, due to the formation of burrs, which slows down the fluid flow rate and forces unreasonably to increase the working pressure in piping systems, which dramatically reduces the operational performance of not only the passage of fluid flow, but also leads to gusts of transport above-ground and underwater systems for supplying liquid and particles, which collapses during the operation of pipes, burrs, which, falling into the valves and control -measurement equipment, simultaneously disables auxiliary equipment and shut-off and valve equipment. A tool for automated cutting and hardening of welds is difficult to manufacture and operate and requires significant costs for the use of used aircraft turbines in gas pumping, providing a high-speed flow of air from the blowing-out beads after machining.

Known patent No. 20360 dated 04/25/2001 "Device for protecting the internal weld of pipelines" - / 2 /.

The task of protecting the object of intellectual property, a useful model is the versatility of a new technical solution with simultaneous technical excellence in protecting against destruction of welded joints directly from the inside of the pipe product, for example, according to patent 20360.

The task is achieved in that a combined pipe tee, characterized in that, from the side of the 3 end protrusions, adapters are welded to the ends, the welds are cleaned from the inside, and the boundary areas are laid on the outer contour, which are limited by the size L and chamfers, the inner surfaces of the nozzles are prepared for rigid connection with the protective shells, the inner profile of the pipe tee combined is cleaned and provided with a corrosion-resistant coating.

Description of the combined pipe tee.

Combined pipeline tee (1), characterized in that:

1. from the side of 3 end protrusions (4-6), adapters (10-12) are welded to the ends (7-9);

2. welds (13-15) are cleaned from the inside;

3. a protective coating is applied along the outer contour (16) whose boundary zones are limited by size L and chamfers (17-19);

4. the inner surfaces of the nozzles (20-22), prepared for rigid connection with the protective shells;

5. The internal profile of the combined pipe tee is cleaned and provided with a coating (31).

An example of a device with the practical use of protective shells.

Combined pipe tee (1), perform in such a way that:

- from the side of 3 end protrusions (4-6), adapters (10-12) are welded to the ends (7-9);

- welds (13-15) are cleaned from the inside;

- a protective coating is applied along the outer contour (16) whose boundary zones are limited by size L and chamfers (17-19);

- the inner surfaces of the nozzles (20-22), prepared with the possibility of connection with the shells (23 and 24) with an adhesive ring seam (25 or 26);

- on the shell (23 or 24), rubber seals (27 or 28) are placed along the axis (3 or 2), which are limited from axial displacement by annular collars (29) or plates (30);

- the internal profile of the combined pipe tee is cleaned and provided with a coating (31);

- on the clip (23, 24), the risk is applied (32) or the corner profile (33);

- the weld (34) is designed to connect a tee to one of the pipelines (35), the number and length of which are determined from technological calculations of the supply of a liquid medium.

The industrial usefulness of the new technical solution lies in the fact that the pipelines are guaranteed to be protected from penetration of the weld bead into the liquid medium supplied through the pipeline, which contributes to the high-quality operation of valve-stop equipment and pressure meters, and the practical use of devices can be applied to pipe bends with pipes welded to them and with installed protective shell transitions providing practical use of pipe with anti-corrosion ion coating compounds, for example as shown in Figures 1-2.

The delivery condition of the combined tee may take into account the possibility of separate configuration with nozzles without installing shell adapters with installing shell protection of the welded joint in various versions, shown in figure 1 and figure 2. at the place of their operational use, which is especially important for installation operations in the field.

The economic efficiency of the new technical solution is to increase the durability of the pipeline joints, which ensures the safety of pipelines with acids and alkalis, including the transportation of other aggressive liquid media through the pipelines, for example, in the form of liquid nitrogen, ammonia, benzene compounds and other liquid components.
