CN201407429Y - High-temperature and abrasion resistant composited pipe - Google Patents

Abstract

The utility model discloses a high-temperature and abrasion resistant composited pipe. The pipe comprises a metal casing (1) and an abrasion-resistant layer (2) arranged on the inner wall of the metalcasing (1), wherein a hexsteel skeleton structure (3) is arranged inside the abrasion-resistant layer (2). The utility model adopting the structure has the advantages of high-temperature and abrasionresistance, strong thermal state shock resistant capacity, the operating temperature ranging from subzero 50 DEG C and 1,000 DEG C, good weldability and the weight 3-5 times lighter than the originalglass-ceramic pipeline, and can avoid the phenomenon that an abrasion-resistant pipeline is not resistant to high temperature, thereby prolonging the service life by 1-3 times.

Description

The high-temperature wearable composite pipe

Technical field

The utility model relates to a kind of conveyance conduit device, especially is applicable to a kind of high-temperature wearable composite pipe of conveying material.

Background technique

In all conglomeraties such as electric power, metallurgy, coal, mine, chemical industry, usually need pipeline to carry out the conveying of material, owing to the operating mode that these industries are related is more abominable, conveyance conduit should bear higher pressure, temperature, stands serious wearing and tearing again.Often there are shortcomings such as easy to leak, wear resistant corrosion resistant difference in traditional wear-resistant composite tubes.Particularly because structural reason, there is the only phenomenon of wear-resistant non-refractory, often ftractures easily during high temperature, thereby influenced working life of composite pipe.

Summary of the invention

In order to overcome the only deficiency of wear-resistant non-refractory of existing composite pipe, the purpose of this utility model provide a kind of can resistant to elevated temperatures high-temperature wearable composite pipe.

The problem of the required solution of the utility model realizes by the following technical solutions: the wearing layer that it comprises metal shell and is located at the metal shell inwall is characterized in that: be provided with the hexsteel skeletal structure in the described wearing layer.

The said structure that the utility model adopts, high temperature resistant, resistance to wear, hot strong shock resistance, serviceability temperature is at-50 ℃～1000 ℃, and weldability is good, 3～5 times in light weight of the pipeline of more original cast stone, avoided the only phenomenon of wear-resistant non-refractory of abrasion-proof pipe, can make to prolong 1～3 times working life.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further:

Embodiment

By accompanying drawing as can be known, the wearing layer 2 that this high-temperature wearable composite pipe comprises metal shell 1 and is located at metal shell 1 inwall, described wearing layer is provided with hexsteel skeletal structure 3 for 2 li.The utility model adopts metal shell as matrix, interior weldering hexsteel is as skeletal structure, the wearing layer lining can use brown corundum matter high-temperature and wear-proof, hexsteel can adopt T type structure, deployed brown corundum matter high-temperature and wear-proof is inserted T type skeletal structure, after a few hours high-temperature and wear-proof fixed be one, like this, hexsteel can be so that combine more firm with the wearing layer lining.

Claims (1)

1, a kind of high-temperature wearable composite pipe, the wearing layer that comprises metal shell and be located at the metal shell inwall is characterized in that: be provided with the hexsteel skeletal structure in the described wearing layer.
