March 2026 – The Ministry of Industry and Information Technology, the National Development and Reform Commission, the Ministry of Ecology and
Environment, the Ministry of Emergency Management, the People's Bank of China, the State-owned Assets Supervision and Administration
Commission of the State Council, and the State Administration for Market Regulation jointly issued the Action Plan to Accelerate the Renewal and
Retrofit of Obsolete Facilities in the Petrochemical and Chemical Industry (2026–2029).
The Plan clearly sets the goal that by 2029, all renewal and retrofit tasks for obsolete petrochemical and chemical facilities identified in 2025 shall be
fully completed, while newly identified tasks after 2026 shall progress as scheduled. Safety and environmental risks associated with obsolete facilities
will be significantly reduced, positive results will be achieved in pollution and carbon reduction synergy, and the level of intelligence and green
development will be substantially improved.
The implementation of this policy marks that the safety and green retrofitting of obsolete facilities in the petrochemical and chemical industry has
entered a phase of accelerated, all-round advancement.
In petrochemical and chemical production processes, valves are key components for media control, and their sealing performance directly affects the
operational safety and environmental compliance of the plant. For obsolete facilities that have been in service for extended periods—where material
aging and increased risk of seal failure are prominent—eliminating "run, leak, drip, and weep" at the source has become a top priority in enterprise
retrofitting. "Run, leak, drip, and weep" not only cause material loss but also lead to safety hazards (risk of fire and explosion), environmental
violations due to fugitive VOCs emissions, increased maintenance frequency, and higher operating costs. Therefore, green retrofitting may well begin
with sealing.
Bellows seal valves offer excellent sealing performance. They effectively resolve leakage issues caused by material corrosion or aging seals,
significantly reduce fugitive VOCs emissions, enhance plant sealing and reliability at the source, and lower safety and environmental risks. They are an
ideal choice for safety and green retrofitting in the petrochemical and chemical industry.
Wanlong’s independently developed bellows valve series features a multi-seal structure that achieves a true “zero leakage” sealing effect. Suitable
for demanding conditions such as high temperature, high pressure, and corrosive media, these valves fully meet the latest safety and environmental
standards of the petrochemical industry, providing a reliable, long-life sealing solution for the renewal and retrofitting of obsolete facilities.
What’s more, Wanlong owns its foundry, ensuring end-to-end control from raw material sourcing to finished product delivery. This enables highly
flexible, customized sealing solutions—whether the plant layout is compact or the media characteristics are unique, Wanlong can respond quickly
and match precisely. For enterprises currently advancing the retrofitting of obsolete facilities, this means no compromise, only one-stop reliable assurance.
Safety retrofitting allows no margin for error, and environmental compliance brooks no delay. If you are troubled by “run, leak, drip, and weep” in
your obsolete facilities, or wish to upgrade your sealing standards once and for all in the upcoming renewal and retrofitting campaign, please contact
Wanlong. Let us tailor a sealing upgrade solution—from valves to systems—for you, supporting safe, green, and long-term operation of your plant.
