Eddy current testing DTL Materials Tech GmbH has comprehensive quality testing methods that can meet the general requirements of any country, region, or enterprise standard. General standards for centrifugal casting: HG/T 2601-2011, ASTM A608, DIN 10295, JIS G5122... The figure shows the use of eddy current testing equipment to detect the internal smoothness of centrifugal cast pipes. Read More

Penetration testing of precision cast trays The picture shows the PT testing of the hot work fixture grate, which is manufactured using precision casting technology. Casting defects are prone to occur at the connection points of the grate. We conducted a 100% dye penetration test on the precision cast grate to detect defects and promptly repair or scrap the workpiece, effectively controlling product quality. Read More

Dye penetrant testing of tees We have professional dye penetrant testing personnel who can perform PT testing on areas such as casting surfaces, welding grooves, and overall products that require it. The picture shows PT testing of the three-way welding position, which can monitor the welding quality and ultimately ensure product performance. Coloring inspection is a non-destructive testing method, which is a surface inspection method mainly used to detect surface damages such as cracks that cannot be recognized by the naked eye, such as detecting near surface defects (cracks), pores, looseness, delamination, lack of penetration, and lack of fusion in stainless steel materials (also known as PT testing). Suitable for inspecting defects (cracks, pores, etc.) in the surface opening of dense metal materials (welds), non-metallic materials (glass, ceramics, fluoroplastics), and products. Read More

PT testing of welds in centrifugal cast pipes Conversion tubes, radiation tubes, etc. are mainly produced using centrifugal casting technology, and the welding positions between tube sections require 100% PT testing to monitor the welding quality and ensure the final quality of the product. The picture shows the PT inspection of the welding position of the conversion tube, which is carried out by qualified inspectors. DTL Materials Tech GmbH having complete production and testing equipment and facilities, it can meet various inspection and testing requirements. Read More

Centrifugal cast pipe dye penetrant testing The body of the sinking roller is produced using centrifugal casting technology. The picture shows that the sinking roller body is undergoing dye penetrant testing to detect defects that cannot be recognized by the naked eye, such as small cracks. Determine whether it is within the allowable range through professional standards in order to proceed with the next step of production and processing. Read More

Pressure test for radiant tube parts: According to customers' requirements for pressure test, to ensure to meet customer requirements. DTL Materials Tech GmbH is equipped with perfect quality inspection methods, can meet the standards of any country, region or enterprise general requirements. Read More

X-ray inspection of catalyst tubes The picture shows the customer inspecting the goods at the factory and verifying the RT film of the catalyst tube. The advantages of RT testing mainly include intuitiveness, high precision and reliability, wide applicability, intelligence, digitization, and convenience. ‌ Read More

Ultrasonic testing of furnace roll thickness: The picture shows the customer inspecting the furnace rollers on site, using an ultrasonic detector to check the thickness of the furnace rollers. Principle: When ultrasonic waves enter an object and encounter defects, a portion of the sound waves will be reflected. The transmitter and receiver can analyze the reflected waves to accurately detect the defects, display the location and size of internal defects, and measure material thickness. Read More
