Abstract
The utility model discloses a kind of Hermetical connecting structures of seamless steel pipe, including the first steel pipe, retaining mechanism and the second steel pipe；It is provided with tapered protrusion on the outside of the right end of first steel pipe, the left end of the second steel pipe is provided with interior cone mouth, and the first steel pipe on the right side of the tapered protrusion is plugged in interior cone mouth and fixes by the retaining mechanism in outside.The utility model is novel in design, and the tapered protrusion being stamped to form by pipe end and interior cone mouth substitute welded stub connection, easy to operate, improves efficiency, save the cost.
Description
Technical field
The utility model relates to a kind of steel pipe jointing device, the Hermetical connecting structure of specifically a kind of seamless steel pipe.
Background technique
Pipe fitting (Pipe fitting) is the effects of playing connection, control, deflecting, shunting, sealing, support in pipe-line system
The general designation of components.
Steel pipe fittings are pressure-bearing pipe fitting.According to processing technology difference, it is divided into four major class, i.e., (divide has weldering to butt welding class pipe fitting
Two kinds of seam and no-welding-seam), socket weld and threaded fitting, flanged fitting.
The method that the sealed connection of pipeline is welded with union nipple using tube body substantially at present, to reach pipeline assembly in system
In assembly, playing each element in connection system makes it play a role, the production technology of pipe welding pipe fitting can exist because
Heat affected area metallographic structure caused by welding high temperature changes and causes assembly there are hidden danger of quality and pipeline assembly inner cavity because of height
Temperature causes base material oxidation to lead to problems such as assembly cleannes overproof.
Utility model content
The purpose of this utility model is to provide a kind of Hermetical connecting structures of seamless steel pipe, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions:
A kind of Hermetical connecting structure of seamless steel pipe, including the first steel pipe, retaining mechanism and the second steel pipe；First steel
It is provided with tapered protrusion on the outside of the right end of pipe, the left end of the second steel pipe is provided with interior cone mouth, on the right side of the tapered protrusion
First steel pipe is plugged in interior cone mouth and is fixed by the retaining mechanism in outside.
As a further solution of the present invention: the retaining mechanism includes locking nut and lock-on connection.
The locking nut is set on the first steel pipe and on the inside of its right end as a further solution of the present invention,
It is provided with internal screw thread, lock-on connection is set on the second steel pipe and is provided with external screw thread on the outside of its left end.
The locking nut is threadedly coupled with lock-on connection as a further solution of the present invention,.
It is located on the first steel pipe on the right side of the tapered protrusion as a further solution of the present invention, and is also arranged with
Sealing ring, sealing ring outboard end are abutted with the inner wall of interior cone mouth.
Compared with prior art, the utility model has the beneficial effects that the utility model is novel in design, pass through pipe end punching press
Made of tapered protrusion and interior cone mouth substitute welded stub connection, it is easy to operate, improve efficiency, save the cost.
Detailed description of the invention
