Please be informed that our office will be closed from October 1–7, 2026 (7 days) for China's National Day Holiday. We will resume normal operations on Thursday, October 8, 2026.

Qingdao, China — NW HENGYI METAL's technical team participated in the 1st National Cathodic Protection Conference, hosted by the China Society for Corrosion and Protection. As the first national gathering dedicated entirely to cathodic protection (CP) technology in China, the event brought together leading researchers, senior engineers, and industry managers to exchange the latest research, materials, and engineering solutions in the field.

In cathodic protection (CP) of buried metallic structures such as well casings, pipelines, and storage tank bottoms, anode groundbed performance directly determines protection effectiveness. NW HENGYI METAL supplies MMO tubular string anodes designed specifically for deep well CP in soil applications — combining high current output with long service life.

In the world of industrial B2B, client development is never about casting a wide net — it's about precise targeting.

If you purchase mixed metal oxide (MMO) titanium anodes — whether for chlor-alkali, wastewater treatment, cathodic protection, or electrolytic copper foil — you've likely noticed upward pressure on pricing.

The performance of a titanium anode is defined by its catalytic coating. Key parameters such as coating uniformity, thickness, composition, crystal structure, and microscopic morphology directly determine electrochemical activity, service life, and current efficiency.

NW HENGYI METAL recently completed a project for a cathodic protection application in a soil environment, where the customer specified an iridium-tantalum coating at 5μm—a specification that sits at the higher end of the typical range for MMO anodes in this industry.

China's titanium anode industry has evolved from a period of import dependence and technological catch-up to one of independent innovation and global leadership. Its growth is closely tied to the nation's industrialization, particularly in key sectors such as chlor-alkali chemicals, environmental protection, and marine engineering.

​As the Christmas and New Year holidays approach, NW HENGYI METAL hosted a special year-end celebration to express gratitude to our hardworking employees. The event featured a warm and festive hotpot dinner, bringing everyone together to share delicious food and joyful conversations.

The integrity of a cathodic protection (CP) system depends on every single component. Beyond our industry-leading MMO (Mixed Metal Oxide) Titanium Anodes, the unsung hero ensuring sustained performance is the critical connection – the cable. Today, we are proud to detail the engineering excellence behind our standard and robust cable system, the backbone that delivers protection to your assets.
