POSCO,& two partner companies , develop new technology. Acquired certificates.
POSCO is trying to co-exist through joint development of new products with small and medium-sized enterprises (POSCO’s customer). President Woo Ji-hyun of EVERTECH, Choi Kyu-seo, head of POSCO's stainless steel marketing department, and Lee Dong-jin, vice president of Daechun (from left), are celebrating NET(New Excellent Technology) certification.POSCO has jointly developed with POSCO’s customer a new technology that replaces copper tube used as refrigerant tubes/pipes for air conditioners by using high-elongation stainless steel (PossFD) developed with premium steel types. POSCO's Stainless Steel Marketing Office and POSCO’s Steel Solution Research Lab. have been jointly developed with EVERTECH Corporation and Daechun for a year since March last year, and acquired NET certification from MOTIE(Ministry of Trade, Industry and Energy) earlier this year. This is best practice case of corporate citizenship Activities as POSCO developed new technologies with customers in the supply chain. Korea government new technology certification system is a system to promote the commercialization of new technologies and technology transactions by finding new technologies early and certifying their excellence.The certification acquired this time is "high-elongation stainless steel tube forming technology for refrigerants," which combines POSCO's high-quality steel, Daechun’s pipe forming and heat treatment, and EVERTECH Corporation's non-welded Hookjoint. It is a technology that can replace existing copper tube by using high flexibility stainless steel tube for air conditioner tube with excellent corrosion resistance. High-elongation stainless steel tube which is named PossFD has similar flexibility to the copper tube, but is more than twice as strong, so it has good pressure-resistance and durability. In addition, Daechun's forming pipe and heat treatment technology improves precision and ensures formability, making it easy to work on the construction site, and by applying EVERTECH Corporation's “HOOK JOINT” non-welded technology, can eliminates the risk of fire that occur during pipe welding. Through this, the construction time can be shortened and the sealing ability to prevent leakage of refrigerant gas is improved. [Han Woo-ram, Maeil Economy & mk.co.kr, 2021.2.23.] -

To prevent fire accident of refrigeration warehouse. … ‘Attention’ Non-welding piping connection technology
The connecting piping technology not required welding that can prevent fire accidents in refrigeration warehouses is drawing attention.▲ Icheon city Logistics Warehouse(above) and Namyangju city officetel accident site where a fire accident broke out during pipe welding.A recent fire accident in refrigeration warehouse caused by careless work has shocked in Korea. In April last year, a fire broke out at a logistics warehouse construction site in Icheon city when a spark is transferred to urethane foam on the wall while worker welded refrigerant pipes, killing 38 people. In addition, in April, a fire broke out again during welding pipes for an air conditioner outdoor unit at a 19-story officetel construction site in Namyangju city, killing one worker who was working.As such, non-welding connection piping technology is drawing attention to prevent large fires from occurring due to embers generated during pipe welding. According to the National Fire Information System, a total of 5,829 welding accidents occurred between 2015 and 2019, and by location, industrial facility construction was the highest at 31.1%. This resulted in a total of 444 casualties, 32 deaths and 412 injuries.Number of fire caused by welding from 2015 to 2019 (Source: National Fire Information System).In terms of economics, The fire damage caused by welding was about 1.6 times higher than the overall average. The property damage caused by welding is 99.593 million KRW, compared to the total fire property damage of 53.748 KRW million per case. Casualties and property damage from welding fires from 2014 to 2018 (Source: the Korea Occupational Safety and Health Research Institute (OSHRI)The strength of non-welded connection piping technology is that it literally secures higher sealing ability by connecting pipes without welding, and it is easy for non-skilled people to construct pipes by being only acquainted with manual. There is no welding process. So, accidents caused by fire and harmful gas can be fundamentally blocked, and there are no restrictions on working hours and working conditions because the working time is short and electric power is not required.These non-welded joints have been released to the market by companies such as Daechun, Vulkan, EVERTECH Corporation, and Parker Korea, replacing welding with advantages such as safety and simplicity compared to existing products. -

[Company specialized in Non-welding tube connection technology for refrigerant tube] EVERTECH CORPORATION
EVERTECH Corporation that is one of the leading companies of pipe joint for stainless steel water pipe , launched a ‘Hook Joint for air conditioner tube’ with the know-how and technology accumulated over a long period of time in the pipe joint market for water supply and presented a new paradigm for refrigerant tubing construction for air conditioner. ‘Hook Joint’ for air conditioner tube is an eco-friendly product with excellent safety, sealing, and economic feasibility and can be simply constructed by hand without special tools and it is an eco-friendly tube joints that fundamentally eliminates the risk of fire. EVERTECH released seven types of hook joints △Elbow △ Flare elbow △Union elbow △ An official from EVERTECH said, "Hook joint received NET from MOTIE(Ministry of Trade, Industry and Energy) along with POSCO and Daechun company and was recognized for its technology and innovation by receiving LH new technology Certification" and "Accordingly, the approval process is rapidly progressing by the air conditioner maker which has the right to approve its own supply materials." An official from EVERTECH emphasized, "The use of high-elongation stainless steel tube as a replacement for copper tube will continue to increase, and above all, Hook joint for refrigerants, which can be used not only for stainless pipes but also for existing copper pipes, will gradually expand the market." 2021.11.30
