 1. Countries Strongly Supporting Nuclear Power Development


Driven by carbon neutrality goals, energy security and stable base‑load power supply, nuclear energy has regained strong policy support worldwide.


 China: Committed to tripling nuclear capacity by 2050, accelerating construction of Hualong‑1 units in Fujian, Guangdong , Shandong and JiangSu. Large‑bore HDPE/PP/PVDF pipelines are extensively used in nuclear auxiliary systems, greatly boosting demand for heavy‑duty hot plate butt welding machines.
 France: Maintains nuclear as the main power source, planning six new EPR reactors The first unit is expected to be operational in 2038, with large‑diameter high‑pressure PE/PP pipe networks in cooling and auxiliary s
ystems.
 Russia: Actively promotes VVER reactors domestically and overseas (Vietnam, Egypt, Bangladesh), with consistent demand for heavy‑duty pipe welding equipment.
 Emerging markets: Vietnam, Indonesia, Saudi Arabia, the UAE and many African countries are launching or planning nuclear projects, requiring massive HDPE/PE100 pipeline infrastructure and supporting welding machines.


Nuclear‑grade pipelines must meet strict pressure, corrosion resistance and long‑term safety standards, which directly drives procurement of high‑pressure, large‑diameter, automatic butt welding equipment.


 2. Impact on Hot Plate Welding Industry & Surge in Equipment Demand


Nuclear power construction brings a long‑term, high‑quality growth cycle to the hot plate welding industry, especially for high‑pressure butt welders and large‑diameter PE/PP pipe fusion machines.


 Booming procurement for nuclear‑grade pipe welding
Nuclear projects require a large number of HDPE, PP, PVDF pipelines for cooling water, desalination, fire protection and auxiliary systems. In recent bids across China and Southeast Asia, fully automatic hot plate butt welders, high‑pressure butt welding machines and multi‑angle welders have seen significant increase in bidding volume and order frequency.


 Technical upgrading and market expansion
Market growth: The global market for nuclear‑related hot plate welding equipment is growing at 20%+ annually, with China's share rising steadily.


Higher technical requirements: Nuclear applications demand stable high pressure, precise temperature control, data traceability and reliable long‑term operation.


Complete industry chain: From equipment manufacturing and process development to after‑sales service, the nuclear welding equipment sector has formed a mature supply ecosystem.
