-
Abstract
In allusion to the lower safety in welding/stoppling operation for small—diameter thin—wall high— pressure pipeline,non-welding stoppling cross and stoppling head as well as stoppling process are developed.More than 600 times field uses display that the non—welding stoppling technology is available for safety operation and has a significant spreading and application values.
