Welded Conical Pipe Video

Welded Conical Pipe, also known as tapered welded steel pipe, is a special-shaped custom steel pipe with a conical variable-diameter structure. It is professionally manufactured by cutting, rolling, positioning and precise welding of high-quality steel plates or steel strips. Different from ordinary straight cylindrical welded pipes with equal diameter, this product features gradual inner and outer diameter taper change, smooth variable-diameter transition and integral structural uniformity. With unique conical mechanical structure and excellent pressure diversion performance, it is a non-standard special pipe specially used for diameter conversion, flow adjustment, structural transition and equipment matching in industrial and municipal engineering.

The product adopts professional conical rolling and tailored welding process. Through numerical control precise blanking and segmented rolling forming, the pipe body presents uniform and natural taper without local distortion or indentation. It adopts automatic submerged arc welding and high-frequency welding integrated process, with firm weld fusion and smooth transition. The whole process is calibrated by professional taper detecting tooling to ensure accurate taper angle. Conforming to national steel pipe production standards, it supports customized taper, length and wall thickness. Conventional materials include Q235B, Q345B low alloy steel and carbon structural steel, which feature high structural strength, good toughness and stable welding performance.

All finished Welded Conical Pipes undergo full-range professional testing before delivery, including taper precision detection, dimensional tolerance calibration, weld nondestructive flaw detection (UT), hydrostatic pressure test, structural stability test and surface quality inspection. All products comply with industrial manufacturing standards, with complete qualification certificates and inspection reports. Support third-party authoritative testing to ensure stable and reliable product quality and meet high-standard engineering assembly requirements.
