Abstract
The utility model discloses a hard-wearing pipeline applicable to conveying concrete, comprising a steel pipe (1) and connecting flanges (2,3) welded with the steel pipe (1); inner faces of the steel pipe (1) and the connecting flanges (2,3) are covered with a layer of nickel-phosphorus alloy coating (4). The utility model has advantages of good wearing nature, strong corrosion stability, light weight, long service life and simple technique, of which the service life is more than 3 times the service life of prior pipelines.
Description
Technical field:
The utility model relates to a kind of pipeline, particularly relates to a kind of abrasion-proof pipe of delivering concrete.
Background technology:
In the middle of the construction of key state project and city high rise building mansion, extensively adopt the concrete conveying equipment delivering concrete at present, these concrete conveying equipments adopt concrete-conveying through tubes, these delivery ducts are welded with butt flange at the two ends of steel pipe, and the resistance to abrasion of delivery pipe is had higher requirement.The delivery duct that has is at the whole surface build-up welding of the inside face of steel pipe, and improving the resistance to abrasion of steel pipe, but the resistance to abrasion of the delivery duct of this structure is not too high, the processing technology more complicated, and increased the transporting resistance of delivery duct.
Summary of the invention:
Technical problem to be solved in the utility model provides that a kind of resistance to abrasion is better, the life-span is long and the simple concrete conveying pipe of processing technology.
The technical solution adopted in the utility model is: the inside face at steel pipe and butt flange is coated with one deck alloy-layer.
Because the utility model has adopted technique scheme, is coated with one deck alloy-layer at the delivery duct inside face, so the utility model resistance to abrasion is good, corrosion stability is strong, and is in light weight, and the life-span is long, and technology is simple, and cost is lower, service life before being more than 3 times.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
Referring to Fig. 1, be welded with butt flange 2,3 at the two ends of steel pipe 1, be coated with one deck ni-p alloy coating 4 at the inside face of steel pipe 1 and butt flange 2,3.
The utility model resistance to abrasion is good, and corrosion stability is strong, and is in light weight, and the life-span is long, and technology is simple, and cost is lower, service life before being more than 3 times.
Claims (2)
1, a kind of abrasion-proof pipe that is suitable for delivering concrete comprises steel pipe (1) and the butt flange (2,3) that welds with described steel pipe (1), and it is characterized in that: the inside face at described steel pipe (1) and butt flange (2,3) is coated with one deck alloy-layer (4).
2, the abrasion-proof pipe that is suitable for delivering concrete according to claim 1 is characterized in that: described alloy-layer (4) is a ni-p alloy coating.
