FORGED FRICTION WELDED DRILL PIPES. Our forged and friction welded pipes are state of the art in drill pipes. This technology can increase resistance on the weld, which is obtained by the upsetting of the extremity of the tube where the friction weld is made, coupled with the extreme strength of the special steel used for the production of the tool joints and the maximized life of the threads thanks to the Producing holes in tubing - The FabricatorMay 15, 2003 · Like piercing, tube punching can be subcategorized into: Single punching. Straightthrough punching. Double punching. Single punching has already been described. When a single punching station produces a throughhole or multiple holes, a pickup pin can be employed to locate the tube for subsequent hits by picking up from previously punched holes (see Figure 4).Pipeline Equities - A Brief History of Steel PipeWelded pipe is formed by rolling steel strips through a series of grooved rollers that mold the material into a circular shape. Next, the unwedded pipe passes by welding electrodes. These devices seal the two ends of the pipe together. This process in the United States was opened in 1832 in Philadelphia.

See allSee all imagesHow steel pipe is made - material, manufacture, making welded pipe or tubes for construction Hole drillingThere are two types of steel pipe, one is seamless and another has a single welded seam along its length. Both have different uses. Seamless tubes are typically more light weight, and have thinner walls. They are used for bicycles and transporting liquids. Seamed tubes are heavier and more rigid. The have a better consistency and are typically straighter. They are used for things such as gas transportation, electrical conduit and plumbing. Typically, they are used in instances when the pipe is not put under a See more on madehow welded pipe or tubes for construction Hole drillingHow is a lap joint drilled in a pipe?For the lap joint process, a round hole is drilled in the pipe wall using a collaring head. After the tube wall is penetrated, two forming pins are extended from the drill bit. The collaring head then automatically withdraws from the main run pipe and forms a collar in readiness for the branch tube.See all results for this question
