Abstract

一种内防腐管接口焊缝处的内补口环,方便现场 施工,达到缺口处防腐的目的。它是在两管端接口处 有内衬防腐弹性套2,弹性套外周面上有凹形环槽, 环槽里镶有金属环1。

Description

本实用新型涉及一种内防腐管对接处无防腐层的补口环。
内防腐管由焊接连成管道。由于某种原因,如焊接可造成对口处无防腐层漏口环,使整个管道各对接处还存在无防腐层的漏口环,达不到防腐要求。为了焊口处的内防腐,有的在漏口环上打孔涂覆法、搪瓷法和内涂镀法,这些方案因有的不便于在现场施工,有的保证不了质量,劳动效率低等而没有得到应用。
本实用新型的目的在于克服上述现有技术中缺点之处,而提供一种方便现场施工可达到防腐要求的内防腐补口环。
本实用新型的目的可以通过以下技术方案来达到:在两管端接口处有内衬防腐弹性套,套外周面上凹形环槽镶金属环。
上述弹性套可为橡胶套或弹性聚氨脂套,金属环可为陶瓷环。
本实用新型相比上述现有技术可具有如下效果:方便现场施工,效率高,可满足内防腐管接口焊缝处对防腐的要求。
图1是本实用新型全剖结构图;
图2是图1安装在内防腐管接口焊缝处全剖结构图。
下面结合附图将对本实用新型作进一步说明:
由图2所示,结合内防腐管的规格和防腐层3的厚度来制成有防腐性能的弹性套2,在两管端接口处插进弹性套2,即在两管端连接口处有内衬弹性套2,与防腐管4的内壁、防腐层3的端口密封接触;弹性套2外的周面上有凹形环形槽,槽里镶有金属环1,金属环要对准管端焊缝,使焊缝位于中部。
上述弹性套2可由具有防腐性能的橡胶或聚氨脂制成,金属环1可为陶瓷环。其弹性套两端有安装锥度。
使用前,对管端内壁及防腐层端口作一处理,再将本补口环插进一管端一半,另一半插入另管端面后进行点固焊。
本补口环可根据防腐管的规格及内防腐层的厚度作成系列产品,安装后与防腐层同一内壁。
