Description

全钢内螺纹保护器
本实用新型全钢内螺纹保护器,用于石油套管和各种管材端部内螺纹的保护。
目前国内外同类产品的内螺纹保护器,有全钢、钢塑结合及全塑三种,全钢螺纹保护器因螺纹部位未经柔性处理,如遇到外部冲击力过大或拆装时易将管部的螺纹损坏,钢塑和全塑螺纹保护器在特殊情况下遇上外部强大的冲击力易变形及损坏。
本实用新型全钢内螺纹保护器发明的目的是提供一种全钢套体,上部带外檐及上油槽、中部位带螺纹、下部位带下油槽并将螺纹表面采用柔性材料进行涂层处理,能进一步的保护管材螺纹及拆装灵活、是一种抗冲击力强的螺纹保护器。
本实用新型全钢内螺纹保护器,发明的目的是这样实现的,钢套1上部设有外檐5,在该下部设有上油槽3,中部设有螺纹2,下部设有下油槽4,该螺纹2表面喷涂一层具有柔性强、粘接力好的材料。
本实用新型全钢内螺纹保护器,因采用无缝钢管及合理的设计,能抗击不同角度在特殊情况下强大的冲击力,在上下油槽的作用下,拆装十分灵活省力。螺纹表面涂有一层柔性材料后,实现了钢柔相济,能与管壁的内螺纹紧密配合,确保管体螺纹不受任何损伤,适应各种复杂的气候和特殊工作环境。
本实用新型全钢内螺纹保护器有以下视图及实施例给出:
图1为本实用新型全钢内螺纹保护器主视图并带局部剖视图。
本实用新型全钢内螺纹保护器,是由钢套1上部设有外檐5,并在外檐5下部位设有上油槽3,中部设有外螺纹2,下部位设有下油槽4,构成全钢内螺纹保护器,钢套1选用5mm-10mm厚的无缝钢管,根据不同产品、不同规格进行切断,采用热锻成型技术将钢套1制成设有外檐5和1∶16-1∶20之间斜度、上宽下窄对称向内倾斜。然后加工出外螺纹2,并在螺纹表面均匀的喷涂一层具有柔性强的材料,外檐5上设有拆装孔6。
