The invention relates to a method for producing a number of pipes (100) with a predetermined pipe diameter. The method includes feeding multiple pipe parts (101, 102) with the predetermined pipe diameter to a welding station (53), aligning in each case a first pipe part (101) and a second pipe part (102) coaxially with respect to one another and axially adjacent to one another, welding the pipe parts (101, 102) by means of a fully encircling weld seam (109) to form a pipe run (104), conveying the pipe run (104) to a cutting station (57) in a machine direction (A) downstream of the welding station (53), and cutting off the number of pipes (100) in a respectively designated length from the pipe run (104).

A laser cutting apparatus conveyable within a casing lining at least a portion of a wellbore that extends into a subterranean formation. The laser cutting apparatus includes a housing, a deflector, a motor, a sensor, and a processing device. The deflector rotates relative to the housing to direct a laser beam to form a radial slot extending through the casing and into the subterranean formation. The motor rotates the deflector. The sensor generates information related to depth of the radial slot in real-time as the radial slot is formed by the laser beam. The processing device receives the information generated by the sensor and causes the motor to rotate the deflector based on the received information.

The invention relates to a method for producing a polymer-enhanced pipeline element, in particular of a fire extinguishing installation, and to a pipeline element and a pipeline system of a fire extinguishing installation. It is proposed according to the invention to provide a first a first and a second hollow body, to align in each case one encircling edge surface of the hollow bodies with one another, to weld the two hollow bodies to one another along the encircling edge surfaces such that an encircling weld seam is generated which has a root extending on the inside of the pipeline element, and to apply a polymer-based layer to the inside of the pipeline element, wherein the polymer-based layer completely covers the inside of the pipe element and the root of the weld seam.

The present disclosure provides a method of all-position plasma welding process for titanium alloy pipeline, which may be used for welding a titanium alloy pipeline made of TA2 or TC4, with a wall thickness of 3˜16 mm, and a pipe diameter of 108 mm or more. When the wall thickness is 3˜9 mm, a keyhole type technology may be used for one-time welding formation, and when the wall thickness is 9˜16 mm, grooving treatment needs to be performed for the pipeline, and the keyhole type technology is used for backing welding, and then filling welding and covering welding are performed using filler wire welding through a melt-in technology. The method includes following steps: S1: performing pre-welding treatment for the pipeline; S2: clamping the pipeline; S3: setting welding parameters; S4: starting the welding.

A system for inspecting an interior surface of a girth weld region of a pipeline includes a robot that includes a scanner mounted on a carriage for scanning the interior surface of the girth weld region to generate surface profile data. A profile analyzer receives the surface profile data and outputs an indication of whether the interior surface of the girth weld region is suitable for being coated. In some embodiments, an imaging system captures images of the girth weld region as it is being scanned. In a method of coating the girth weld regions of a pipeline, the images of a girth weld region found to be unsuitable for being coated based on the scanning data are used to certify whether the girth weld region is suitable for being coated.

A laser processing apparatus of the present disclosure controls outputs of a blue laser oscillator and an infrared laser oscillator such that before a surface oxidation is detected on a workpiece, the workpiece is irradiated with at least blue laser light, and after the surface oxidation is detected on the workpiece, power of infrared laser light with which the workpiece is irradiated is increased as compared to before the surface oxidation is detected.

A backing plate for includes a synthetic diamond portion configured to abut a joint region during a welding operation. A welding clamp includes a plurality of clamping blocks, each including a synthetic diamond portion configured to abut a pipe joint region during a welding operation. Because the backing plate and clamping block each include a synthetic diamond portion, the backing plate and clamping block can withstand high welding temperatures without damaging or diminishing the quality of the weld.
