摘要
当前输送天然气用大口径涂塑焊管国内需求量大,生产厂家少。指出了这种涂塑焊管内涂层为改性环氧塑膜(EP),外涂层为线性低密度聚乙烯塑膜(LLDPE),并介绍了其生产的关键工艺技术。
Nowadays the demand for plastic -co ated large -sized steel pipes for natural gas transport is rather big,whereas producers for this kind of pi pe are far from enough.It is identified that the pipe is internally coated with epoxy or EP,and externally coated with liner low -density polyethylene or LLDPE.Also described here is the key techni ques con-cerning the tube coating.
