油管清洗用高压水射流技术

High pressure waterjet technology for oil pipes cleaning

油田油管清洗是个很大的市场，以高压水射流清洗工艺取代传统的化学清洗工艺设计了油管内外壁同步清洗装置［１］．介绍了在此基础上开发的第二代油管清洗装置产品，其特点是实现了上管、清洗至下管全过程的手动与自动控制，安全可靠．装置同时适用２５″（６２ｃｍ）与３″（７６ｃｍ）油管的清洗，同时，对不同垢层的油管清洗速度无级可调，进一步提高了清洗效率．对油管外壁的清洗，开发了大直径（Ｄ２００ｍｍ）高压旋转喷头，是一项实用性很强的高压水射流技术．

There is a great market for oil pipes cleaning. A simultaneous cleaning equipment was designed depending on high pressure waterjet cleaning technology instead of the traditional chemical cleaning process. The secondary generation product for oil pipes cleaning is described. Its speciality is the realization of manual and automatic control of oil pipes lifting, cleaning and loading down, it is very safe and reliable. The equipment is satisfied to the cleaning of 2 5″ and 3″ oil pipes, the cleaning speed could be justified randomly to different layer of dust. Thus the cleaning efficiency is further improved. For the outer surface cleaning, the major diameter high pressure rotary head is developed. This is a very practical technology of high pressure waterjet technology.
