Ding Testing & Inspection: Coupon Corrosion Testing, In-depth Insight into Material Corrosion Resistance
In various stages of industrial production, the corrosion resistance of materials is a key factor in ensuring the long-term stable operation of equipment. Coupon corrosion testing, as an important means of assessing the corrosion resistance of materials in specific environments, plays an irreplaceable role in preventing and reducing corrosion damage. Ding Testing & Inspection's coupon corrosion testing service, with its professional technical strength and precise testing methods, provides comprehensive corrosion risk assessment and management for enterprises.
Service Introduction
Since 2023, Ding Testing & Inspection (DTI) has accepted over 500 batches of material inspections and corrosion tests witnessed on-site by internationally renowned inspection agencies each year. Our services are supervised by well-known inspection agencies, recognized by internationally leading users, and endorsed by top-tier manufacturers and engineering firms in the industry!
Ding Testing & Inspection's coupon corrosion testing service monitors and analyzes the corrosion behavior of materials in different media by simulating actual working conditions. Corrosion coupons are divided into Type I and Type II, with different surface areas, and corrosion coupons are also divided into copper, carbon steel, and stainless steel according to different materials.
The general test cycle for corrosion coupons is 1-3 months, and the corrosion rate of carbon steel after correction is 0.075 mm/a; copper and stainless steel are both 0.005 mm/a. If it is cleaning and pre-filming, there is another set of standards, welcome to click the phone on the right to obtain, this set of standards is actually only the conversion of units, because there is acid washing, this standard will be much higher than the above-mentioned standards.
Our services include, but are not limited to, corrosion rate determination, corrosion type identification, corrosion mechanism analysis, and recommendations for corrosion prevention measures. Using advanced testing equipment and scientific experimental methods, we can provide accurate and reliable corrosion data and professional recommendations for enterprises.
Industry Pain Points
Corrosion problems are common in industries such as chemical, petroleum, marine, papermaking, and food processing. They not only lead to a decline in material performance and equipment damage but may also cause safety accidents and environmental pollution. Traditional corrosion detection methods often lack targeting and accuracy, and cannot meet the high standards of enterprises for corrosion risk management.
