Description
Technical field
It the utility model is related to a kind of steel pipe, and in particular to a kind of seamless steel pipe.
Background technology
In existing seamless steel pipe, generally all without setting insulation construction or thermal insulation material is used, and some seamless steel pipes
Need to work in the environment of high temperature and pressure, such as boiling water tube, steam pipe, therefore have to the heat insulation effect of seamless steel pipe certain
It is required that.And pipeline is made of Steel material, easy heat conduction or heat absorption, and heat losses are larger during relatively long distance conveying, without preferable
Heat insulation effect.And what the seamless steel pipe equipped with insulation construction was generally integrated, the weight of steel pipe is not only increased, but also protecting
Needed during the damage of warm structure or steel duct in integral replacing or maintenance, it is time-consuming and laborious and uneconomical.
And after insulation construction is set in existing seamless steel pipe, can not other structures or device just be set, it is such as cold
But structure, therefore the function of seamless steel pipe will be relatively simple, it is impossible to suitable for plurality of devices.
Utility model content
The purpose of this utility model is to provide a kind of seamless steel pipe, which is that can keep the temperature or more work(of cooling fluid
Energy steel pipe, simple in structure, anti-pressure ability is strong, light weight convenient transportation.
To achieve these goals, the technical solution adopted in the utility model is：Including steel pipe body, it is characterised in that：
Several grooves are provided with the steel pipe body；The outer sheath of the steel pipe body is equipped with casing, casing include upper casing and
Setting of casing, is provided with and the matched protrusion of groove shapes on the upper casing and setting of casing；In the upper casing and setting of casing
The hollow setting in portion, upper casing and setting of casing inside filling thermal insulation material or coolant；The upper casing and setting of casing pass through bolt
Fastener is fastenedly connected.
The utility model is further arranged to, and the upper casing and cased outer wall are equipped with several in correspondence with each other
Mounting groove, be provided with through hole on mounting groove；The bolt fastener includes bolt and nut, and bolt is matched somebody with somebody through through hole with nut
Close the upper casing of fastening and setting of casing.
By using above-mentioned technical proposal, upper casing and setting of casing can be fastened by bolts part and split and install, and carry
When can separate carry, mitigate weight；Destruction of the extraneous factor to steel pipe main body is avoided that using casing, when steel pipe main body or set
When there is inevitably damage in pipe, it is not necessary to which entirety is replaced or maintenance, saves material, economical rationality；In casing
Portion sets insulating layer or coolant, when the fluid of transport needs insulation, is protected using the casing for being provided with thermal insulation material
Temperature, when needing to cool down transport fluid, need to only remove the casing of thermal insulation material, replace the casing equipped with coolant and cooled down.
The utility model is further arranged to, and the groove and raised cross section are arch or arc, groove and
Male cooperation is installed.
The utility model is further arranged to, the quantity at least two that the groove is set, and all along steel pipe body
Set to uniform intervals.
By using above-mentioned technical proposal, the groove in steel pipe main body is set and is overarched or arc, steel pipe can be strengthened
The anti-pressure ability and non-deformability of wall, and can preferably keep the temperature or cooling fluid.
The utility model is further arranged to, and the upper casing and setting of casing arrange two sets, and one is sleeved in upper and lower casing
Portion sets insulating layer, another set of to set coolant in upper and lower inside pipe casing.
The utility model is further arranged to, and the thermal insulation material selects polyurethane heat insulation material, and coolant uses second
Glycol coolant.
By using above-mentioned technical proposal, no casing can be used in different demands, improves the quality of fluid, energy
Maximize the utilization rate of seamless steel pipe.

Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not intended to limit the scope of the present invention.
The utility model is illustrated below with reference to Fig. 1 to Fig. 4.
A kind of seamless steel pipe, including steel pipe body, are provided with several grooves 5, the number of groove 5 in the steel pipe body
Set according to the diameter of steel pipe main body 4, the excessive anti-pressure ability for setting groove 5 to lower steel pipe main body 4 on the contrary, groove
5 cross section is set to arch shape or arc shape, can strengthen the anti-pressure ability and non-deformability of steel pipe, and arch or arc
Contact area is big, can make the better of insulation or cooling；The outer sheath of the steel pipe body is equipped with casing, and casing includes upper
