SVG Becomes Official Supplier for China’s West-East Gas Pipeline Fourth Line

Wenzhou, China – SEVEN VALVE GROUP (SVG) was formally approved as a Class-A supplier for the West-East Gas Pipeline Fourth Line, one of China’s largest energy infrastructure projects. SVG will supply over 1,200 large-diameter gate valves and ball valves (DN800 to DN2000/32" to 80") compliant with API 600 and GB standards.

The pipeline, spanning 3,000+ kilometers, will transport natural gas from Xinjiang to eastern China, supporting the country’s clean energy transition. SVG’s valves were selected for their superior corrosion resistance (using Alloy 20 and stainless steel materials) and long service life (designed for 30 years of continuous operation).

“ Being part of this national key project reflects SVG’s technical strength in large-scale pipeline valves,” said  Doris Cai. “Our products have passed 1000+ hours of fatigue and leakage tests, ensuring zero failure in harsh operating environments.”
