TL;DR: In this article, an austenitic stainless steel pipeline welding process is described, where the welding process includes the following steps: performing pre-welding positioning on pipeline weld junctions according to pipe diameter of pipelines and certain rules so as to divide into a plurality of welding sections.

TL;DR: In this article, the utility model discloses a pipeline inspection looks into ware with sweeping, include: can be at pipe inner wall circumferential direction's rotary mechanism to and bear rotary mechanisms and can drive the crawl mechanism at pipe internal wall linear motion, and the welding seam is swept to look into and is provided with at least internal surface and surface that the TOFD probe subassembly that goes on detecting in a pair of heat affected area that is used for the butt welded seam and a pair for the tail welding seam on the frame and carries out the PA

TL;DR: In this article, a TOFD detection method for docking ring welding seams of a cylinder is presented, where the detection method comprises the following steps: dividing the cylinder into a first to be-detected area, a second to-be-detectable area and a third to-detective area in the thickness direction of each welding seam according to the characteristics of the welding seams, and continuously and stably moving each probe pair along the axis of each weld seam, repeatedly executing the previous step, performing D scanning on each detecting area in a circle of the circumferential

TL;DR: In this paper, the utility model discloses a pipeline inspection is with sweeping drive car of looking into ware, include: the bottom plate, assemble in a drive controller and an at least action wheel mechanism on the bottomplate, action wheel mechanisms include with step motor that drive controller electricity is connected, with drive sprocket axle that step motor connects and install respectively in stretch out at the drive sprock axle both ends the initiative wheel that bottom plate both sides and then supporting baseplate are liftoff, follow on the preceding baffle has been installed to wheel advancing direction's position,

TL;DR: In this article, the utility model discloses a PE (Polyethylene) ultrasonic testing and calibration test block, which comprises a body, wherein the body is a cuboid with a rectangular section, one end of the body extends to form a first arc-shaped surface with the radius of 2R and the thickness of being smaller than that of a body.
