"WSC" is a casing tube with excellent strength and threading. It can be safely used as an essential threaded casing for replacing perforated PVC pipes, galvanized pipes, screens, etc. The threaded joint section uses special steel, and to ensure thread strength, we custom order our original size from the pipe manufacturing company. Additionally, it undergoes heat treatment to provide appropriate hardness and toughness. 【Features】 ■ The thread shape has been revised to withstand the powerful impact energy of air hammers and the pulling force during extraction, dispersing stress. ■ The remaining thickness of the threaded joint is also considered, and the inner and outer diameters are machined. ■ With the processing precision that Welman is particular about, skilled technicians cut high-precision threads and assess them by touch. *For more details, please refer to the PDF document or feel free to contact us.

Our company offers the essential reaming bit for the dual-pipe method, the 'ADMS (Adams) W Type'. The blade attachment has been improved from the structure relying on pin holes provided in conventional devices, eliminating the risk of pin dislodgment. Additionally, improvements to the pilot bit section have enhanced the upward movement of slime (cuttings) and the weight balance. 【Features】 - Structure that is resistant to hole bending - Locking mechanism to prevent diameter reduction during drilling - Reinforced blades increase the reaming section by 60% (compared to our conventional model), allowing for smooth bit rotation - The blade retention structure has been changed from pin hole type (our conventional model) to eliminate pin dislodgment - Easy disassembly, inspection, and replacement of parts *For more details, please download the PDF or feel free to contact us.
