Abstract

The utility model relates to an additional strengthening is restoreed to perforation pipe, the main part of pipe is hollow cylindrical shape structure, is equipped with a plurality of beaded finishs at pipe outer wall spacer sleeve, has the overlay in the even cladding of the hole of perforation pipe. This pipe is to the hole build -up welding one deck high performance wear -resistant material of perforation pipe reach the standard grade before, and the high temperature resistance of reinforcing pipe is difficult for appearing the heat fatigue phenomenon under high temperature for has stronger abrasion resistance under the fricative operational environment of pipe high temperature.

Description

A kind of perforated conduit repairs reinforcement structure

Technical field

This utility model belongs to process equipment auxiliary apparatus field, relates to a kind of perforated conduit and repairs reinforcement structure.

Background technology

Conduit is one of important parts in perforation foreground, perforated conduit is to be promoted hot steel billet to enter the instrument being responsible for guiding in the process of perforating machine by pusher, generally select cast steel material, the temperature of hot steel billet is 1280 DEG C, every 40 seconds will cross once hot steel billet, conduit is normal steel casting material, do not possess heat resistance, it is easy to that wear-out defect occurs, very easily hot steel billet outer surface is caused damage, finally affect outer surface of steel tube quality, catheter length is 2600mm, spot check person is descended to check in working order, it is difficult to ensure that the conduit under duty is qualified instrument, need shutdown inspection comparatively frequently, production efficiency is relatively low.

Utility model content

The purpose of this utility model is in that to overcome the deficiencies in the prior art part, it is provided that a kind of design science is reasonable, simple in construction, perforated conduit reliability and durability, low cost of manufacture repair reinforcement structure.

A kind of perforated conduit repairs reinforcement structure, and the main body of conduit is the cylinder barrel shaped structure of hollow, at conduit outer wall spacer sleeve equipped with multiple reinforcing rings, it is characterised in that: the endoporus at perforated conduit is uniformly coated with overlay cladding.

And, the overlay cladding end face at perforated conduit axial end portion is shaped with the transition conical surface.

Advantage of the present utility model and having the benefit effect that

1, this conduit endoporus built-up welding one floor height performance wearable material to perforated conduit before reaching the standard grade, strengthens the heat-resisting quantity of conduit, heat exhaustion phenomenon at high temperature not easily occurs so that have higher wear resistence under the working environment of conduit high temperature friction.

2, the conduit of this structure is in normal steel transportation amount situation, can use the time of 2 months, improve 4-5 times service life than the conduit of non-built-up welding, it is ensured that stablizing of the tube quality in this region, effectively alleviates the work of spot check person.

Accompanying drawing explanation

Fig. 1 is that this utility model partly cuts open structural representation；

Fig. 2 is A portion partial enlarged drawing in Fig. 1.

Detailed description of the invention

Below by specific embodiment, the utility model is described in further detail, and following example are illustrative, is not determinate, it is impossible to limits protection domain of the present utility model with this.

A kind of perforated conduit repairs reinforcement structure, and the main body of conduit 1 is the cylinder barrel shaped structure of hollow, is used for the hot steel billet of conveying that leads；At conduit outer wall spacer sleeve equipped with multiple reinforcing rings 2, increase the intensity of conduit.

Innovative point of the present utility model is in that:

Endoporus at perforated conduit is uniformly coated with overlay cladding 3, strengthens heat-resisting quantity and the wear resistence of perforated conduit inner surface.

Overlay cladding end face at perforated conduit axial end portion is shaped with the transition conical surface 4.

The present embodiment overlay cladding can adopt the H08A welding wire built-up welding of built-up welding to form uniform clad; the crushing resistance wearability thermostability of resurfacing welding material is all higher than perforated conduit; can effectively protect perforated conduit surface injury-free, without the cost of perforated conduit is significantly increased.

Chemical composition (GB1300-77) C≤0.1 of H08A welding wire；Mn0.35～0.6；Si≤0.03；Cr≤0.2；Ni≤0.3；Cu≤0.2；S, P are not more than 0.03.Repair welding layer is high temperature resistant, wear-resisting, good toughness；Repair welding material is strong with the adhesion of cast steel, does not fall off under high temperature；Decrease the quantity making new perforated conduit, reduce cost.

Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope without departing from this utility model and claims, various replacements, to change and modifications be all possible, therefore, scope of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.

Claims

1. a perforated conduit repairs reinforcement structure, the main body of conduit is the cylinder barrel shaped structure of hollow, at conduit outer wall spacer sleeve equipped with multiple reinforcing rings, it is characterised in that: the endoporus at perforated conduit is uniformly coated with overlay cladding, and the overlay cladding end face at perforated conduit axial end portion is shaped with the transition conical surface.
