Abstract

本实用新型涉及一种高耐磨特高压弯头，包括弯头，其特征在于弯头外侧设有一层加厚耐磨层，加厚耐磨层从内弧侧的厚度到弯头外弧侧的厚度是逐渐增大的。本实用新型具有能增强弯头背部耐磨性的优点。

Description

高耐磨特高压弯头
技术领域
本实用新型涉及一种弯头，尤其涉及一种高耐磨特高压弯头。
背景技术
弯头为管件、管道连接件，是用来改变管道输送介质流动方向的；弯头是流通介质拐弯的地方，是整个管道的薄弱环节，弯头内弧侧为应力集中区，而外弧侧则为磨损区。在高压管道集气过程中，管道内部受介质的腐蚀，在流体动力学因素作用下，产生严重的冲刷破坏，对弯头外弧侧的磨损尤其严重，而现有弯头在成型过程中一般是外弧减薄的，且强度不高，在高压流体介质的冲刷破坏下最易发生穿孔、泄漏和开裂的事故，因此存在严重的安全隐患；尤其是在海工钻井平台采油高压管汇用的弯头由于弯头外弧受海水冲刷是磨损最严重的区域。
发明内容
针对上述缺点，本实用新型的目的在于提供一种能增强弯头背部耐磨性的高耐磨特高压弯头。
本实用新型的技术内容为：一种高耐磨特高压弯头，包括弯头，其特征在于弯头外侧设有一层加厚耐磨层，加厚耐磨层从内弧侧的厚度到弯头外弧侧的厚度是逐渐增大的。
本实用新型与现有技术相比所具有的优点是：本实用新型的整体壁厚较大，尤其是背部厚度，大大提高了弯头的使用强度及耐磨性。
附图说明
图1为本实用新型的结构示意图。
图2为图1中A-A向示意图。
具体实施方式
如图1和图2所示，一种高耐磨特高压弯头，包括弯头1，其特征在于弯头1外侧设有一层加厚耐磨层2，加厚耐磨层2从内弧侧的厚度S1到弯头外弧侧的厚度S2是逐渐增大的。
