Abstract

The utility model provides a wear-resisting bent tube for industrial roads, which comprises a layer of outer tube (1) of a steel bent tube. The utility model has the improvement that the outer tube (1) is provide with a layer of inner tube (2) of the steel bent tube; a molten layer (3) made from molten antifriction alloy and white iron is arranged between the outer tube (1) and the inner tube (2). After the inner tube (2) of the wear-resisting bent tube with the structure is worn out, the molten layer (3) made from the molten antifriction alloy and the white iron has favorable wear-resisting property. The utility model has the advantages of light weight, simple manufacturing technique and low cost.

Description

A kind of abrasion-proof bent tube

The utility model relates to a kind of wear-resisting pipe, particularly abrasion-proof bent tube that is used for industrial pipeline.

At present, at the known abrasion-proof bent tube that is used for industrial pipeline, the wear-resisting composite-curve of cast stone is arranged, it has one deck steel pipe bend pipe outer tube, in outer tube compound one deck glass-ceramic tubre wear-resisting in the pipe, the abrasion-proof bent tube of this structure has good abrasion resistance, its deficiency is that its weight is big, the combination process complexity, the manufacture cost height.

The purpose of this utility model is to provide a kind of abrasion-proof bent tube, to overcome the deficiency of known technology.

The utility model is achieved in that a kind of abrasion-proof bent tube, it comprises one deck steel elbow pipe outer tube (1), its improvements are to have pipe (2) in one deck steel elbow pipe in outer tube (1), have the antifriction alloy white iron cast layer (3) of one deck casting between outer tube (1) and interior pipe (2).

The utility model abrasion-proof bent tube can be that antifriction alloy white iron cast layer (3) is a molybdenum vanadium white cast iron cast layer.

The utility model abrasion-proof bent tube can be that antifriction alloy white iron cast layer (3) is a manganese molybdenum copper vanadium white cast iron cast layer.

The utility model abrasion-proof bent tube can be that antifriction alloy white iron cast layer (3) is a chromium nickel cast iron cast layer.

The utility model abrasion-proof bent tube can be that antifriction alloy white iron cast layer (3) is the rich chromium cast iron cast layer.

The utility model abrasion-proof bent tube can be that antifriction alloy white iron cast layer (3) is chromium 28 cast layer.

The utility model abrasion-proof bent tube can be that antifriction alloy white iron cast layer (3) is chromium 15 molybdenums 3 cast layer.

The abrasion-proof bent tube that the utility model provides, antifriction alloy white iron cast layer (3) had good abrasion resistance after pipe (2) was worn in it, and it has advantage in light weight, that manufacturing process is simple, cost is low.

Fig. 1: the master of a kind of structure of the utility model abrasion-proof bent tube looks sectional view.

The utility model is described in further detail in conjunction with the embodiments with reference to accompanying drawing.

Embodiment 1, Fig. 1 has provided a kind of concrete structure of the utility model, consult Fig. 1, a kind of abrasion-proof bent tube, it comprises one deck steel elbow pipe outer tube (1), in outer tube (1), have pipe (2) in one deck steel elbow pipe, between outer tube (1) and interior pipe (2), have the antifriction alloy white iron cast layer (3) of one deck casting.Antifriction alloy white iron cast layer (3) can be a molybdenum vanadium white cast iron cast layer; Antifriction alloy white iron cast layer (3) can be a manganese molybdenum copper vanadium white cast iron cast layer; Antifriction alloy white iron cast layer (3) can be a chromium nickel cast iron cast layer; Antifriction alloy white iron cast layer (3) can be the rich chromium cast iron cast layer; Antifriction alloy white iron cast layer (3) also can be chromium 28 cast layer; Antifriction alloy white iron cast layer (3) can also be chromium 15 molybdenums 3 cast layer.Antifriction alloy white iron has good wear resistance, but its bad mechanical property is difficult for welding.Its outer tube of the abrasion-proof bent tube of this structure (1) has the favorable mechanical performance, and pipe (2) has played the effect of internal mold at casting cycle in it, and pipe (2) wearing and tearing back antifriction alloy galvanized iron cast layer (3) have good abrasion resistance in the pipeline running.It has in light weight, the advantage that manufacturing process is simple, cost is low.
