Abstract
The utility model discloses a seamless straight reducer of high pressure thick wall heavy -calibre, include the segmental arc, be located the straight tube section A of segmental arc one side, be located the straight tube section B of segmental arc opposite side, straight tube section A's diameter is less than straight tube section B's diameter, the segmental arc is the reducing to along straight tube section A's one end to straight tube section B's one end radius grow gradually, be provided with anti -corrosion layer on segmental arc, straight tube section A and straight tube section B's the inner wall, just the thickness of stating segmental arc, straight tube section A and straight tube section B is the same. The utility model discloses a being provided with the segmental arc and linking together straight tube section A and straight tube section B, the segmental arc can reduce contact stress, improves the life of tapered pipe, through be provided with anti -corrosion layer on the inner wall of tapered pipe, can prevent that intraductal fluid from to the erosion of inside pipe wall, further improving its practical life.
Description
Technical field
This utility model belongs to metal tube technical field, is specifically related to a kind of high pressure heavy wall large-calibre seamless Concentric Reducers.
Background technology
Along with growing and scientific and technical the advancing by leaps and bounds of pipeline conveying industries, the prescription of the bend pipe tools needed for pipeline is connected is more and more higher, demand is increasing.The operating pressure being conventionally recognized by more than 10.0MPa for high-pressure pipe member.In known technology, mesolow pipe fitting produces comparatively general, and Highpressure Reducers realizes mainly by forging.Current reduced pipe carries out transition connection generally by conical section, it is easy to cause contact stress to concentrate, and reduces the service life of reduced pipe, and the inwall of reduced pipe is vulnerable to erosion effect simultaneously.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of high pressure heavy wall large-calibre seamless Concentric Reducers.
This utility model is to be achieved through the following technical solutions:
A kind of high pressure heavy wall large-calibre seamless Concentric Reducers, including segmental arc, it is positioned at the straight length A of described segmental arc side, is positioned at the straight length B of described segmental arc opposite side, the diameter of the described straight length A diameter less than straight length B, described segmental arc is reducing, and becomes larger along one end of straight length A to one end radius of straight length B；The inwall of described segmental arc, straight length A and straight length B is provided with anticorrosion layer, and described in state the thickness of segmental arc, straight length A and straight length B identical.
Further, described anticorrosion layer includes waterproof film layer, enhanced film layer and adhering film layer.
Further, the inwall of described adhering film layer and this reduced pipe bonds together, and described waterproof film layer is between described adhering film layer and enhanced film layer.
Further, the thickness of described waterproof film layer, enhanced film layer and adhering film layer is identical.
Further, described straight length B radius is 1.3-1.8 times of straight length A radius.Further, the centrage of described straight length A and the centrage of straight length B are on same straight line.
Compared with prior art, the beneficial effects of the utility model are: this utility model is provided by segmental arc and is linked together by straight length A and straight length B, segmental arc can reduce contact stress, improve the service life of reduced pipe, by being provided with anticorrosion layer on the inwall of reduced pipe, it is prevented from the erosion to inside pipe wall of the fluid in pipe, improves its physical life further.
