Advanced EGW Vertical Seam Welding Machine for Thick-Wall Tanks

Product Introduction:
The EGW Series revolutionizes vertical welding for ultra-thick storage tanks (e.g., LNG, LPG, cryogenic vessels). Featuring dual-wire tandem EGW technology, it achieves deposition rates exceeding 25 kg/h (55 lbs/h), welding plates up to 100mm thick in a single pass. Integrated oscillation and real-time seam tracking ensure flawless fusion in critical applications requiring ASME Section VIII or API 620 compliance. Ideal for shipyards and heavy fabrication shops.

Key Specifications:

Key Features:

• Industry-Leading Speed: 2x productivity vs. standard EGW for thick sections.

• Deep Penetration: Dual-arc synergy ensures full fusion on 100mm plates.

• Active Arc Control: Independent parameter adjustment for each wire.

• Zero-Defect Guarantee: Auto-correction via seam tracking & oscillation.

• Remote Monitoring: Real-time weld analytics via IoT interface.

• Cryogenic-Ready: Optimized for 9% Ni steel, stainless steels, and aluminum alloys.

Application Scenarios:

• LNG/LPG storage tanks (API 620, Appendix Q).

• Cryogenic vessels (-196°C service).

• Thick-wall reactor shells in petrochemical plants.

• Nuclear waste containment tanks.

• Offshore platform leg sections & gravity-based structures.

Wincoo Engineering Co., Ltd (WINCOO) is engaged in bringing the most suitable solutions/equipments for client, fabricators, EPC/C companies on pipe fabrication, tank construction, pipeline construction, industrial production lines, clean energy project and other industrial field.

We have ability of providing workable solutions to support clients to be awarded with shorter project execution time, fewer man-hour cost and higher efficiency construction/fabrication method and better quality during phase of project bidding.

Based client’s facility/site space availability, we are able to study/design and present matched configurations on project schedule, quality, cost and productivity to guarantee production pace is accordance with project requirement.

To support project execution, we are always ready to work as fireman to give prompt supply on project materials from different consumables, tools, equipments/machines to special merchandise. With flexibility, we are also glad to perform as procurement agent in China to seek required supply resources.

Our products covers tank welding machine, tank hydraulic jacking system, pipelayer, paywelder, pipeline groove machine, pipeline bending machine and other tank/pipeline construction equipment, etc.

To familiarize clients fast to use equipment/lines/system we supplied, we can arrange engineers to implement installation, training, and commission. Meanwhile, to better support client to finish their projects, we provide operators for construction, operation or we are able to undertake such work as subcontractor.

We can provide OEM service, all the equipment/lines supplied we can produce with client’s brand.

To verify what we supply can well satisfy clients’ requirement, we sincerely would like to invite client to visit us before issuing order. We prefer to set factory acceptance test process before shipment to remove clients’ concerns.

Your support is our forward motivation.
