Product Overview
The fully automatic inner welding machine for flexible pipelines (DW48/56-8H-D) is an automatic welding equipment for the inner ring seam of pipelines developed by Denvo/engine Welder for mountainous, hilly, long-distance pipeline networks and other complex working conditions. The equipment adopts Core Technology such as high torque servo drive, hydraulic expansion and fast response electromagnetic brake. It is equipped with 8 welding units and is suitable for Φ1219-Φ1422mm large diameter pipes. The single welding time is ≤ 120s. The pipeline pairing and root welding can be completed in only about 5 minutes, which greatly improves the construction efficiency and welding quality of complex pipelines.
The compact fuselage design significantly improves the bending performance and complex terrain passability of the equipment. With wireless remote control, it can penetrate into harsh environments such as mountains, hills, urban comprehensive pipe galleries and chemical parks. It is a key equipment for automated welding of inner ring seams in long-distance oil and gas pipeline projects.
