Abstract

一种同心异径管，包括同心异径管本体，同心异径管本体左右两端设有焊接坡口。本发明由于在同心异径管本体的两端设置了焊接坡口，方便了同心异径管和管道之间的焊接，缩短了同心异径管和管道之间连接时间，提高了施工效率，同时采用镀锌板作为同心异径管的材料，增强了同心异径管的强度，延长了同心异径管的使用寿命。

Description

一种同心异径管
技术领域
本发明涉及一种管道安装配件，特别涉及一种同心异径管。
背景技术
随着石油化工产业不断发展，管道的运输也随着壮大起来，对于管道的安装和配件的要求也不断严格，在管道安装中常常需要用到同心异径管，目前很多同心异径管都没有留有焊接边，使得同心异径管和管道不能够很方便迅速的进行连接，增加了人力和经济的投入，降低了施工效率，同时由于同心异径管和管道常常用来运输腐蚀性能较强的原材料，使得同心异径管内壁常常被腐蚀，造成同心异径管表面出现裂纹，降低了同心异径管的表面强度，缩短了使用寿命。
发明内容
本发明的目的是克服现有技术的不足，提供一种结构简单，制作容易的一种同心异径管。
为实现上述目的，本发明的技术方案为：
一种同心异径管，包括同心异径管本体，同心异径管本体左右两端设有焊接坡口。
所述的同心异径管本体采用镀锌板。
本发明的优点是：
本发明由于在同心异径管本体的两端设置了焊接坡口，方便了同心异径管和管道之间的焊接，缩短了同心异径管和管道之间连接时间，提高了施工效率，同时采用镀锌板作为同心异径管的材料，增强了同心异径管的强度，延长了同心异径管的使用寿命。
附图说明
附图1中为本发明的结构示意图。
图中1为异径四通本体，2为焊接坡口，3为焊接坡口。
具体实施方式
如图所示：一种同心异径管，包括同心异径管本体1，同心异径管本体1，左右两端设有焊接坡口2和3，同心异径管本体1采用镀锌板。

Claims (2)

1.一种同心异径管，包括同心异径管本体，其特征在于：同心异径管本体左右两端设有焊接坡口。
2.根据权利要求1所述的一种同心异径管，其特征在于：所述的同心异径管本体采用镀锌板。
