In late January, during the National Symposium on the Management of Storage, Sales, and Use of Chlorofluorocarbons (CFCs) held in Luzhou, Zhejiang Province, it was revealed that some companies were using CFCs in disguised ways for refrigeration systems. The issue of CFC-11 products came under scrutiny, with delegates urging national authorities to enhance oversight of the storage, sale, and use of these ozone-depleting substances. They emphasized the need for strict management even after production has been phased out.
CFCs have long played a crucial role in various industries, including refrigeration, air conditioning, cleaning, and aerosols. However, their harmful impact on the ozone layer led to their classification as ozone-depleting substances, prompting global efforts to phase them out. Under the "China CFC/CTC/Halon Accelerated Phase-out Plan Agreement" signed by China and the Multilateral Fund Executive Committee, the State Environmental Protection Administration and China Chemical Construction Corporation signed a production phase-out contract with six major CFC manufacturers in Jiangsu Province in June 2007.
These companies included Jiangsu Changshu Sanaifu Fluorine Chemical Co., Ltd., Jiangsu Meilan Chemical Industry Co., Ltd., Zhejiang Dongyang Chemical Co., Ltd., Zhejiang Lantian Environmental Protection High-tech Co., Ltd., Linhai Limin Chemical Co., Ltd., and Zhejiang Suihua Fluorine Chemical Co., Ltd. Except for Zhejiang Suihua, which retained one production line to manufacture 550 tons of CFCs annually for pharmaceutical aerosol use over two years, all other companies ceased production by July 1 of last year—two and a half years ahead of schedule. This achievement marked the successful completion of the Montreal Protocol's phase-out targets.
By July 2007, China had eliminated approximately 100,000 tons of CFC production and consumption, accounting for about 90% of its total output. While significant progress has been made in protecting the ozone layer, challenges remain in ensuring proper management of CFCs post-phase-out.
Despite the official ban, some companies continued to produce and sell CFC-11 in secret, undermining the use of alternative products like F141b, which the government has promoted. A recent letter from the State Administration of Environmental Protection called for stricter enforcement and monitoring.
At the symposium, Yang Lirong, deputy director of the Foreign Economic Affairs Office at the State Environmental Protection Administration, announced the development of the "HCFC Storage and Sales and Use Management Plan," aimed at addressing issues related to the legal use of HCFCs in sectors such as refrigeration maintenance and pharmaceutical aerosols. The plan will outline supply methods and measures to prevent illegal sales and usage.
Wang Kaixiang, deputy director of the Foreign Economic and Trade Office, emphasized that the draft "HCFC Storage and Sales and Use Management Plan" is designed to meet the legal demand for refrigeration and pharmaceutical aerosol industries from 2008 to 2010. Effective management requires collaboration among government agencies, industry associations, enterprises, distributors, and consumers.
To ensure the continued legal use of CFCs in key industries, the state stored 500 tons of CFC-11 and 3,000 tons of CFC-12 in 2006 and 2007. Zhejiang Suihua Fluorine Chemical Co., Ltd., the only company permitted to retain a CFC production line, is limited to producing no more than 550 tons of CFC-11 and CFC-12 combined over two years. Last year, it produced exactly 333 tons of CFC-11 and 2,067 tons of CFC-12, adhering strictly to quotas.
Experts stress that managing CFCs after production has ended remains a complex challenge requiring nationwide cooperation. On one hand, government departments must enforce regulations, support compliance, and ensure the legal supply for essential industries. On the other, they must strengthen laws and improve oversight of sales and use to guarantee full implementation of the national phase-out plan.
Oval Steel Pipe
We supply these Oval Steel Pipes in different sizes, shapes and designs as per clients` specifications at reasonable price. Galvanized oval steel pipes has excellent mechanical properties and presents the desirable combination of high strength and good workability. The cross-section has a special shape, has a large moment of inertia and a section modulus, has a large bending and torsion resistance, which can greatly reduce the structural weight and save steel. Galvanized oval steel tube has a Welded Steel Pipe with a hot-dip galvanized or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of the Steel Pipe and prolong the service life. Galvanized oval steel tube has a wide range of uses. In addition to line pipes for conveying water, gas, oil and other general low-pressure fluids, it is also used as oil well pipes and oil pipes in the petroleum industry, especially offshore oil fields, and oil heaters for chemical coking equipment. Condensation cooler, coal distillation wash oil exchanger pipes, as well as trestle pipe piles, pipes for supporting frames of mine tunnels, etc.
We offer two different types of oval pipe forms.One is the elliptic pipe and the other the flat oval type.
