Managing aging pipeline infrastructure is an important part of overall pipeline risk management. The critical risk management questions for an aging infrastructure are: how quickly should replacement occur and what parts of the system should be prioritized for replacement. To answer these questions it is necessary to...

As the polyethylene pipes widely used in the gas fields, their long-term life is demanded more and more strict. The technical requirement about carbon black particle size was defined in the revised ISO 4437 :2007 as one of requirements of material. We can see that carbon black particle size of the compound is an...
