Producing tubes with fine tolerance and surface roughness
Over the years, Forever Machinery has designed and manufactured dozens of precision tube mills for automobile and power transmission industrial, which were all meticulously engineered with carefully selected components.
Being a leading high-quality ERW tube manufacturer in South Korea, E&G steel contracted Forever Machinery for supply of 7 precision ERW tube welding lines to complement its already-strong product range.
Located within 100km from South Korea’s capital Seoul, this 40,000-square-metre freshly constructed manufacturing facility will be one of the largest private investments in South Korea’s thriving ERW tube industry.
The 7 precision ERW tube welding lines include 3 sets of HG38 ERW tube mill lines, 3 sets of HG76 ERW tube mill lines and 1 set of HG159 ERW tube mill line with quick change system. The new steel tube manufacturing plant will be capable of producing high precision ERW tubes ranging from 1/2” to 6” with a thickness from 0.6mm to 8mm upon successful commissioning. Boasting an annual production capacity of up to 250,000 tons, this project consolidates E&G Steel’s leading position in Korea’s ERW tube industry and further boost its competitiveness in the global market.
Over the past two years, the COVID-19 pandemic has disrupted supply chains and international travel. A crunch on containers and cargo ships is still in place and shows no sign of easing. Putting customer’s interests as our top priority, Forever Machinery has gone beyond its ways to tackle production obstacles faced due to COVID restrictions in order to meet the requirement of customer’s project milestone. With our effort, all 7 tube mill lines are now safely packed and loaded, ready to go on their journey to bring forward their intricate technology to contribute to the Korean economy.
With travel restrictions and quarantine measures imposed, dispatching commissioning engineers to site poses additional challenges and uncertainties. Forever Machinery was determined to make arrangement for several engineers to travel abroad to provide additional assurance to the customer and safeguard the production process, even though this meant enormous additional cost.
Design and configuration of the new tube mill line meet the strictest requirements regarding product precision and changeover time. Forever Machinery’s custom design of horizontal roll stands and vertical roll stands is carefully engineered to achieve a precise dimensional tolerance of ±0.03mm.
The hydraulic-driven quick change system installed for the HG159 tube mill line is also engineered to allow for a much faster changeover time than traditional tube mill, significantly boosting the production efficiency of the heavy-duty structural tubes and increasing product flexibility.
For the past two decades, Forever Machinery has always placed innovation and optimizing roll forming process at the core of the business, developing new configuration and new technology to be implemented in tube mill lines to meet the ever-changing requirements of tube and cold-rolled profile manufacturers. Owing to modernization measures and continuous innovation, Forever Machinery has earned many loyal customers and supplied more than 1000 ERW tube mills lines to domestic and international manufacturers. In today’s steel industry, where “intelligent manufacturing” and “smart manufacturing” is becoming a trend, Forever Machinery will keep automatizing the ERW tube mill, further enhancing the cost-effectiveness of the ERW tube making process, help promote the development of the manufacturing industry.
We pride our selves in our 30 years’ experience in roll form engineering and ERW tube mill design. We look after our customers every step of the way throughout the entire manufacturing lifecyle and offer our insights & services on optimizing their roll form equipment.
