Abstract

The utility model relates to a pipe fitting which prevents damage or abrasion in a pipe or similar members, conveying material in bulk pneumatically via a pipeline or the pipe. The pipeline or a pipe joint conveys articles via a pipeline or the pipe by fluid flow or pressure; the outer side wall of a pipeline connector is provided with an outer casing; an anti-wear layer is arranged between the outer side wall of the pipeline connector and the outer casing. The utility model strengthens and increases the wearability of the pipeline connector, avoiding that the pipeline connector is worn out untimely, extending the service life of the pipeline with 10-20 times, and particularly increasing the work efficiency of pipeline. The utility model has the advantages of simple and compact structure, low cost, convenient application, etc.

Description

Pipeline abrasion-proof bent tube and wear-resisting three-way pipe attaching parts

The utility model relates to in-to-in infringement or the wearing and tearing pipe fitting that prevents pipe or similarity piece, by pipeline or pipe pneumatic conveying loose unpacked material; Pipeline or pipe terminal flow with fluid or pressure is carried object by pipeline or pipe; Particularly pipeline abrasion-proof bent tube and wear-resisting three-way pipe attaching parts.

Industrial employed cleaning shaft and transport the mineral pipe material such as in metallurgy, mine at present, ubiquity in process of production the dust that produces or mineral material hardness height, than great, band corner angle, has great chiseling property of mill, the for example broken factory in mine, ore dressing plant, pelletizing plant, coke-oven plant, Metallurgical Factory, the tail of sintering plant, finished product, the tail of pelletizing plant, the dust that production processs such as base material produce, when handling this type of dust, the speed of dusty gas is up to 18-22M/S in the cleaning shaft, gas dust content 10-20g/M ³High speed dust-contained airflow and the mineral material that transports constantly wash away pipeline, especially the wearing and tearing of bend pipe and three-way pipe position are comparatively seriously outstanding in conduit coupling, cause pipeline can not normally move work, the pipeline mill leaks the service life that wear damage has influenced pipeline, bend pipe and three-way pipe position grind Lou to wear and tear too early in the conduit coupling has not only increased the maintenance engineering amount, during maintain and replace and waste time and energy, waste material during maintenance, fund is bigger, make shortcomings such as pipeline work efficiency effect greatly reduces, solve above-mentioned existing weak point for overcoming, the utility model has designed pipeline abrasion-proof bent tube and wear-resisting three-way pipe attaching parts.

The purpose of this utility model provides and strengthens the resistance to abrasion that increases conduit coupling, avoiding too early, mill leaks the attrition tube pipe connecting, improve conduit coupling service life, improve pipeline service life, improve the pipeline abrasion-proof bent tube and the wear-resisting three-way pipe attaching parts of pipeline work efficiency.

The utility model is achieved in that the lateral wall welded and installed at conduit coupling has body skin, between conduit coupling lateral wall and body skin, has wearing layer, the shape of conduit coupling is bend pipe shape and three-way pipe shape respectively, and wearing layer has glass-cermic powder, diluent sodium silicate, curing agent sodium fluosilicate and the mixing of alloy steel fiber and forms.

400 ℃ of the utility model suitable gas temperature, air-flow velocity 18-22M/S, gas dust content 10-20g/M ³The mineral pipe material that transport in metallurgical cleaning shaft and mine, increased the resistance to abrasion of conduit coupling, avoided too early mill to leak the attrition tube pipe connecting, improved the service life of conduit coupling, improved pipeline service life 10-20 doubly, saved material, fund is bigger, the work efficiency effect that has improved pipeline is particularly outstanding, have simple and compact for structurely, with low cost, advantage such as be easy to make and apply.
