We use polyethylene (HDPE-100 Grade)pipes as internal corrossion protection for carbon steel pipes in water injection and crude oil applications. I would like to know what will be pull force at expansion loops / curves while pulling PE Liner from one end to other end. Is Capstan Effect formula can be used for such type of pulling where theta value is 90 Degree (Pipe line bend angle)? Seeking experts openion in this regard? Thanks in advance - RAM
