Abstract

The utility model relates to a steel belt reinforced coating layer thermal insulation pipeline which is used for building the pipeline work of cold and hot gases (liquid); a heat insulation sleeve (2) is sheathed on a steel pipe (1), a steel belt reinforced composite material coating (bundling layer) (3) is winded on the heat insulation sleeve (2), the surface layer of the composite material is thin steel belts, and the inner layer is adhesion resin; four to five times of the service life of the bundling layer of the utility model can be extended, the maintenance expense can be reduced, the setting standardization and industrialization production can be carried out, simultaneously, the hue of the pipeline work is harmonious with that of the whole buildings, and the environment is beautified.

Description

Steel belt inforced coating thermal insulation pipe

A kind of steel band that relates to strengthens the coating insulation pipe, is used for changes in temperature pipework construction, belongs to structural material.

In existing changes in temperature pipework was built, in order to reduce heat-energy losses and to reduce the transmission of heat energy, in the outside of conveying gas or fluid pipeline, one or more layers was heat insulation for parcel earlier, with the wrapping of fabrics such as canvas glass fibre, applies protection paint at last again.When making clad material with fabric, mostly be artificial manual operations, time-consuming, not only the external layer degree of tightness differs, the surface irregularity of clad, and external form is coarse, and tone is single, has a strong impact on the architectural complex integral color and the harmonious beautification of the environment.Because the fabric layer weather resistance is not good, generally have only 3～4 years working life, fabric layer will take place break and come off, and thermal-protective material is exposed, and causes effect of heat insulation poor.For this reason, at set intervals must maintain and replace, expense is very considerable.At present, in the construction of changes in temperature feed channel, all be first pipe laying at home, wrap up thermal-protective material again, to wrap up at last and paint, operation is more, and the engineering time is long, and multiple working procedure is wanted in maintenance too.Insulation pipe can't carry out shaping standard production in factory, influences the working life and the quality of insulation pipe, has increased the regular maintenance expense.

In view of this, it is a kind of by factory's shaping standard production that the purpose of this utility model just is to provide, and strengthens the coating wrapping with steel band, the apparent size standardization, rich color, can with architectural complex tone harmony, the steel band of long service life strengthens the coating insulation pipe.

The utility model adopts following technical proposals, size according to caliber, on steel pipe, put the thermal-protective coating cover, the outside strengthens the coating wrapping with steel band, coating is to be surface layer with thin steel band, adhering resin is the composite material wrapping of nexine, and formation can be carried out standardization insulation pipe series product in factory.Below in conjunction with drawings and Examples in detail, structure characteristic of the present utility model is described in detail.

Fig. 3 is the axial longitudinal plane structure schematic representation of the utility model

Referring to Fig. 1 to Fig. 3, the utility model it by steel pipe (1), thermal sleeve (2), wrapping layer (3) constitutes.It is the tubing of producing by the NBS typing for a steel pipe (1), only needs to get final product at outer surface brushing one deck rust proof paint of steel pipe (1).Collet (2) is pressed into sleeve pipe with the good material of heat-shielding performance, or directly suppresses on steel pipe with the steel pipe coring.Coating (3) as shown in Figure 3, its structure is divided into two kinds, a kind of is that nexine is an adhering resin as part (3B) type, outer is wrapped on the collet (2) for the thin bonding composite material of steel band, twines by helical type mode, leaves the gap between helical.The second layer also twines by helical type mode, but will with the first layer segment distance that staggers, the interstitial site that makes the center line of second layer individual pen width just in time aim at first layer.Can twine multilayer as required, its winding method is identical with first and second layer.Another kind of structure is (3A) type, and nexine is an adhering resin, and skin approaches steel band for color coating or makes the thin steel band of preservative treatment, and the color of the thin steel band of its color coating can be selected according to the needs of architectural complex integral color harmony, embodies entire environment and coordinates aesthetic feeling.With the insulation pipe of this structure, can only need connection just passable to on-the-spot in factory's mass production.Strengthen the coating insulation pipe with steel band, be more than 20 years its working life, and maintenance cost is few.The utility model not only can be used for changes in temperature gas, fluid pipeline engineering, and needs the occasion of heat-insulation and heat-preservation all can use to all, but the while accelerating construction progress improves warming effect of heat insulation, carries out the standardization mechanization of insulation pipe and produces.Prolong 4～5 times working life, site operation equally can cut and weld with steel pipe, and fitting operation is very convenient.
