DERUI's corporate business focuses on corrosion protection, providing a wide range of cathodic protection materials and engineering services to the Marine and offshore industries.
DERUI manufactures high quality zinc and aluminum anodes, provides the design, assembly and sale of ICCP systems and cathodic protection materials. DERUI is able to provide a full range of services for the successful implementation of cathodic protection projects worldwide, including design, production, consulting, delivery, installation and commissioning supervision.
DERUI is also the sole manufacturer and distributor of POLCOR brand sacrificial anodes in China.
In the field of corrosion protection, DERUI Group has participated in many large-scale international projects, such as the GMMRA project protection in Libya (the world's largest water pipe system) and the Yangshan Project protection in China (the world's largest port). Projects in refining, Marine, FPSO, ports, breakwaters and other large offshore institutions are a good example of DERUI's products and services.
Infrastructure:
Headquartered in Yiyuan County, Zibo City, Shandong Province, the company consists of a professional team of people with rich experience in enterprise management, engineering design, finance, procurement and sales.
The company covers an area of 35,000 square meters, the factory area of 12,000 square meters, equipped with modern production and quality control equipment.
Laboratory:
DERUI has an advanced computer controlled laboratory for chemical composition analysis and electrochemical testing of cathodic protection materials.
The chemical composition analysis of the cast alloy is performed at DERUI's own plant using the ARL3460 spectrum analyzer. According to the operating procedure, one sample is taken for analysis before and after each batch of anodes is cast. All samples are stored for 3 years and analysis records are kept permanently.
The purpose of electrochemical testing is to ensure that the anode produced in each batch meets the required performance. The tests were performed according to DNV RP B401, NACE TM190, and GB/T 17848 standards.
Other types of experiments can also be performed on request
