Abstract
The utility model discloses an end surface groove steel tube; the end surface of the steel tube is provided with an inclined surface and a vertical surface, and the inclined surface is arranged at the upper side of the vertical surface; the inclined angle between the inclined surface and the vertical direction is 30 to 35 degrees, and the height of the vertical surface is 0.5 to 1.0 mm. The end surface groove steel tube ensures the full penetration performance and the welding uniformity. The end surface groove steel tube has mature and stable production process, and can satisfy the requirements of the standard and the customers, and has low investment, promising application prospect and remarkable economic benefit and social benefit.
Description
Technical field:
The utility model relates generally to a kind of steel pipe that has inclined end face.
Background technique:
Domestic production seamless steel pipe pipe end generally all is vertical flat mouthful at present, deburring delivery, and this makes welding the not weld penetration phenomenon occur, influences quality of product.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of end face groove steel pipe to be provided, having solved steel pipe welding not weld penetration phenomenon.
The utility model is achieved through the following technical solutions:
A kind of end face groove steel pipe, it is characterized in that: the end face of described steel pipe includes plane of inclination and vertical plane, and described plane of inclination is positioned at the upside of vertical plane; The angle of inclination of described plane of inclination and vertical direction is 30 °-35 °, and the height of described vertical plane is 0.5-1.0mm.
A kind of end face groove steel pipe, the angle of inclination of described plane of inclination and vertical direction is 32 °, the height of described vertical plane is 0.8mm.
End face of the present utility model is processed into the combination of plane of inclination and vertical plane, can effectively guarantee the welding performance of steel pipe.
The utility model has the advantages that:
Through welding when the utility model has guaranteed the steel pipe welding and the uniformity of welding.Preparation process maturation of the present utility model, stable can satisfy standard and customer requirement; Invest lowly, application prospect is boundless, and its economic benefit and social benefit are very remarkable.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
