Abstract
The utility model discloses a plastic-coated steel pipe, including steel pipe body and protective housing, the steel pipe body sets up in the protective housing, and steel pipe body outside cover has the spiral pipe, and the feed liquor pipe is connected to spiral pipe one end, and the drain pipe is connected to the spiral pipe other end, and the drain pipe all runs through the protective housing with the feed liquor pipe and stretches out to the protective housing outside, fills the heat preservation cotton between steel pipe body and protective housing. The utility model has the advantages that: when external environment temperature crossed low, fill into hot liquid in to the spiral pipe, the spiral pipe gives the steel pipe body with heat transfer, can assist from this and keep warm to the steel pipe body, can improve the bulk strength of steel pipe body through the spiral pipe in addition, conveniently fill the cotton to the protective housing that keeps warm through the filling hole in, fill evenly and closely knit, can indirectly improve thermal insulation performance.
Description
Technical Field
The utility model relates to a plastic-coated steel pipe production technical field especially relates to a plastic-coated steel pipe.
Background
The plastic coated steel pipe, also known as plastic coated pipe, steel-plastic composite pipe and plastic coated composite steel pipe, is one kind of steel pipe with steel pipe as base body. When the plastic-coated steel pipe is used in a cold area, the plastic-coated layer can be locally broken due to too low external temperature, the local failure of the plastic-coated layer of the plastic-coated steel pipe is caused, and the use of the steel pipe is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a plastic-coated steel pipe.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a plastic-coated steel pipe, includes steel pipe body and protective housing, and the steel pipe body sets up in the protective housing, and steel pipe body outside cover has the spiral pipe, and feed liquor pipe is connected to spiral pipe one end, and the drain pipe is connected to the spiral pipe other end, and the drain pipe all runs through the protective housing with the feed liquor pipe and stretches out to the protective housing outside, fills the heat preservation cotton between steel pipe body and protective housing.
Preferably, the protective shell is provided with a plurality of filling holes, and each filling hole is detachably connected with the cover plate.
Preferably, the protective housing comprises two 'U' -shaped plates which are oppositely spliced to form a rectangular frame, and the two ends of the rectangular frame are provided with side plates.
Preferably, both ends of the U-shaped plate are fixedly connected with the edge plate, and the two U-shaped plates are fixed together through the edge plate.
Preferably, a set of support columns is fixedly connected to one side of the protective shell, and the lower ends of the support columns are fixedly connected with the mounting plate together.
The utility model has the advantages that: when external environment temperature crossed low, fill into hot liquid in to the spiral pipe, the spiral pipe gives the steel pipe body with heat transfer, can assist from this and keep warm to the steel pipe body, can improve the bulk strength of steel pipe body through the spiral pipe in addition, conveniently fill the cotton to the protective housing that keeps warm through the filling hole in, fill evenly and closely knit, can indirectly improve thermal insulation performance.

FIG. 1 is a schematic diagram of a basic structure of a plastic-coated steel pipe according to the present invention;
FIG. 2 is a front view of FIG. 1;
FIG. 3 is a connection structure diagram of the steel pipe body and the spiral pipe.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
The utility model provides a pair of plastic-coated steel pipe, including steel pipe body 4 and protective housing 1, protective housing 1 includes two "U" shaped plates, and two "U" shaped plates splice relatively and form the rectangle frame, all are equipped with curb plate 3 at rectangle frame both ends. The two ends of the U-shaped plate are fixedly connected with the edge plate 11, and the two U-shaped plates are fixed together through the edge plate 11. And heat insulation cotton is filled between the steel pipe body 4 and the protective shell 1. Be equipped with a plurality of filling holes on the protective housing 1, every filling hole department all detachably connects apron 5. The heat preservation cotton is conveniently filled into the protective shell 1 through the filling holes, the filling is uniform and compact, and the heat preservation performance can be indirectly improved.
One side of the protective shell 1 is fixedly connected with a group of supporting columns 2, and the lower ends of the supporting columns 2 are fixedly connected with a mounting plate 21 together. Install through mounting panel 21, conveniently install fixedly to steel pipe body 4, steel pipe body 4 inboard is equipped with interior plastic coating.
When using, when external environment temperature was low excessively, filled into hot liquid in spiral pipe 41 through feed liquor pipe 42, rethread drain pipe 43 discharges, and spiral pipe 41 gives steel pipe body 4 with heat transfer, can assist from this to keep warm to steel pipe body 4, can improve steel pipe body 4's bulk strength through spiral pipe 41 in addition.
