Abstract
The utility model discloses a reducing seamless ell with equal walls as the reducing pipe of a pipeline for delivering material. From a big diameter port to a small diameter port, the reducing seamless ell with equal walls is the transition of a cambered surface, and the included angle alpha of the two end faces is less or equal to 90 DEG. The wall thicknesses of the reducing seamless ell with equal walls are homogeneous without forming seams. When the reducing seamless ell with equal walls is connected with a set of pipelines, welding seams are less, so matched pipelines have long lifetime.
Description
The utility model relates to a kind of seamless reducing elbow that is used for conveying material.
In the prior art, turning to of industrial Different Diameter pipeline connects the general iso-diameter elbow that adopts with reducer and with being connected, and weld bond is more, for the conveying material pipeline that has high pressure high strength to require, the increase of weld seam prolongs the construction period, the waste raw material, working life is short, the accident rate height.
The purpose of this utility model provides a kind of seamless reducing elbow.
The purpose of this utility model realizes by following measure, two end face diameter differences of this seamless reducing elbow, and cambered surface transition between big footpath mouthful and the path mouth, its wall thickness is even, angle α≤90 of two end face formation °.
The big footpath mouth of elbow and path mouth diameter differ three grades that are no more than international regulation pipe fitting diameter series.
Embodiment's narration below in conjunction with accompanying drawing.
Fig. 1 is the topology view of reducing elbow.
With reference to Fig. 1 is an embodiment of the present utility model, and its structure is as described below.The both ends of the surface angle α of reducing elbow=90 ° wherein, its big footpath mouth outer diameter D=210mm, path mouth diameter is 159mm.
This elbow wall thickness is even, and is easy to connect with complete pipeline, and whole weld seam is few, can improve supporting pipeline working life.
Claims (2)
1, a kind of seamless reducing elbow is characterized in that its both ends of the surface diameter difference, cambered surface transition between big footpath mouthful and the path mouth, and wall thickness is even, angle α≤90 of both ends of the surface formation °.
2, elbow according to claim 1 is characterized in that its big opening end diameter and osculum end diameter differ three grades that are no more than the pipe fitting diameter series.
