High-pressure seamless steel pipe for boiler

Technical Field

The utility model belongs to the technical field of seamless steel pipe technique and specifically relates to a high pressure seamless steel pipe for boiler is related to.

Background

Need carry the fluid in industrial production and people's daily life, need pressurize the fluid because long distance fluid transport, high pressure makes the fluid can be transported by long distance, and current high temperature high pressure boiler passes through seamless steel pipe transmission to other equipment with the medium in the stove, because the medium concentrates on the boiler and is located the input end department of seamless steel pipe, just so make the internal energy of medium concentrate the release in seamless steel pipe department, will take place surge phenomenon between medium and the seamless steel pipe like this, can cause noise pollution to the surrounding environment on the one hand, on the other hand can make and take place the pine phenomenon between seamless steel pipe and the boiler for a long time, influence the normal transportation of medium, and the work efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: in order to solve current high temperature high pressure boiler and pass through seamless steel pipe transmission to other equipment with the medium in the stove, because the medium concentrates on the boiler and is located seamless steel pipe's input end department, just so make the internal energy of medium concentrate the release in seamless steel pipe department, will take place surge phenomenon between medium and the seamless steel pipe like this, can cause noise pollution to the surrounding environment on the one hand, on the other hand can make to take place the pine between seamless steel pipe and the boiler and take off the phenomenon for a long time, influence the normal transportation of medium, reduce work efficiency's problem, a high pressure seamless steel pipe for boiler is provided now.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a seamless steel pipe of high pressure for boiler, includes the body, be provided with the sand grip along its axial on the internal perisporium of body, one side that the sand grip is close to body direction of delivery is provided with the direction section, the direction section is the setting of leanin gradually to the other end by medium direction of delivery's one end, be provided with a plurality of bump groups on the direction section, the one end that the body internal perisporium was kept away from to the sand grip is provided with a plurality of lugs, the lug sets up along the body axial.

The utility model discloses a set up the sand grip on the internal perisporium of body, contact between sand grip and the medium, thereby make the internal energy of medium consumed, just so play the effect of making an uproar of falling, also make the medium produce the phenomenon of surge through can not releasing too much internal energy simultaneously, and one side that the sand grip is located its direction of delivery sets up the inclined plane, through a plurality of bump groups on the inclined plane, bump group also and the medium between contact each other, thereby make the internal energy of medium can be by further consumption, lug also and the medium between contact each other simultaneously, make the internal energy of medium by further consumption, surge phenomenon has been prevented to appear when the medium is carried to seamless steel pipe.

In order to make the bump groups better contact with the medium, further, the bump groups are arranged along the axial direction of the pipe body, each bump group is composed of a plurality of bumps arranged along the radial direction of the pipe body, and the bumps between every two adjacent bump groups are arranged in a staggered mode. The salient point group is composed of a plurality of salient points, and the salient points in front of the two mutually salient point groups are arranged in a mutually staggered mode, so that the contact surface of the salient points and the medium is improved, the internal energy of the medium can be better consumed, and the phenomenon of medium surge is reduced.

Because the boiler carries the medium to be high temperature high pressure, in order to improve the heat dissipation of body, further, the body periphery wall is provided with a plurality of heating panels. Through set up the heating panel on the periphery wall at the body, the heating panel has increased the heat radiating area of body to improve the radiating efficiency of body, guaranteed that the body heat dissipation is reliable and stable.
