FFX (Flexible Forming and Sizing) technology is one of the most popular forming solutions in the welding pipe industry today. Its core advantage lies in the "shared mold for the opening section," which allows for quick switching between different pipe diameters and cross-sectional specifications, significantly increasing equipment utilization and production flexibility. Whether for mass production or quick switching between small batches of different specifications, the FFX system offers high-efficiency, stable support.
How Does A FFX(Flexible Forming and Sizing Work?
Трубний стан працює шляхом перетворення плоских сталевих смуг або рулонів у зварні сталеві труби за допомогою серії механічних процесів. Перший етап включає розмотування та подачу плоскої сталевої смуги в стан. Потім смуга проходить через ряд роликів, які поступово формують її в циліндричну форму. Коли стрічка проходить через ці ролики, її краї зближуються, готові до зварювання. Наступним ключовим етапом процесу є зварювання. Краї трубок зварюються за допомогою технології високочастотного або лазерного зварювання, яка використовує тепло для сплавлення країв у міцний безперервний шов. Після зварювання трубу пропускають через набір роликів і охолоджувачів, щоб вона зберігала свою форму та охолоджувалася до стабільної температури. Після охолодження трубу випрямляють, щоб усунути будь-які деформації, спричинені процесами формування та зварювання.
Потім труба проходить різні етапи фінішної обробки, такі як обрізання країв, розрізання її на певні відрізки та іноді виконання термічної обробки для покращення її механічних властивостей. Трубка також може бути покрита або відполірована залежно від передбачуваного застосування. Під час цього процесу трубопрокатний стан оснащено системами керування для моніторингу ключових параметрів, таких як швидкість подачі, натяг та умови зварювання, забезпечуючи стабільне та точне виробництво труб. Результатом є високоякісна довговічна зварна труба, яка відповідає необхідним вимогам щодо міцності, розміру та обробки поверхні. Трубні млини використовуються в різних галузях промисловості, включаючи будівництво, автомобілебудування та енергетику, для виробництва труб для конструкцій, трубопроводів та інших застосувань.
Working Principle
The core principle of the FFX forming process lies in the unique design of the opening section, which enables the equipment to produce welded pipes with various diameters and cross-sectional shapes without the need for frequent mold changes. The steel strip is gradually bent into a tubular shape using precise rollers and tooling, and high-frequency induction welding is applied to join the edges of the strip, forming a long pipe. After the forming, the pipe goes through a sizing section to ensure dimensional accuracy and surface smoothness.
Steel Strip Feeding: The unwinder feeds the steel coil into the production line, where the steel strip is unrolled and adjusted before entering the forming section.
Forming: The steel strip is progressively bent into a circular shape by a series of forming rollers. In the opening section, the shared mold design allows for quick adaptation to different pipe diameters without mold changes.
Welding: As the steel strip is formed into a tube, the edges are welded together using high-frequency induction welding, ensuring a strong, high-quality seam.
Sizing and Straightening: After welding, the pipe passes through sizing rollers, which adjust the pipe's diameter and straighten it to meet precise specifications.
Cutting : The finished pipe is then cut to a preset length using a servo-controlled flying saw, ensuring accurate lengths.
Discharge: The cut pipes are transferred to a stacking area or packaging section via conveyor belts, ready for further processing or delivery.
Advantages of FFX Forming
Mold Savings: The shared mold design in the opening section enables quick adaptation to different pipe diameters and cross-sectional shapes without frequently changing molds, reducing mold costs.
Flexibility in Production: The equipment can be quickly adjusted according to production needs, enabling small-batch, multi-spec production to meet changing market demands.
Increased Production Efficiency: The use of high-frequency induction welding and servo-controlled cutting systems ensures the equipment runs efficiently, achieving high-speed production with minimal downtime.
Reduced Downtime: The quick adjustment of molds and production lines minimizes downtime, improving overall productivity.
Real-world Application Cases
Egyptian Customer - 10-inch FFX Welded Pipe Equipment
In 2023, we installed a 10-inch FFX welded pipe production line for a large pipe manufacturer in Egypt. This customer previously only produced small pipes, but with the flexibility of the FFX technology to quickly switch molds, they expanded into large structural pipe markets. Within just six months of equipment installation, they secured several large-scale infrastructure project orders, which helped them open up a new market and achieve significant profit growth. They have since placed an order for a second production line.
