Hot rolled SPA-C steel welding

Our main specifications of medium and heavy plates are thickness 6.0-180mm and width 1400-2700mm. In addition, the ship steel plate has been approved by the factories of the eight-nation classification society such as CCS, ABS, BV, LR, GL, NK, KR, and DNV. Our SPA-C steel welding, medium and heavy plates are widely used in manufacturing, logistics, and automotive industries such as construction machinery, mold processing, ships, bridges, high-rise buildings, pipeline transportation, automobile girders, automobile bridge shells, and pressure vessels.

Ultrasonic flaw detection emits ultrasonic waves to the SPA-C steel welding steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the SPA-C steel welding steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.

09CuPCrNi-A weather-resistant steel plate is one of weather-resistant steel (that is, atmospheric corrosion-resistant steel), used in sulfur-containing flue gas, air preheater, economizer, boiler air preheater, to prevent the vicinity of acid dew point, etc. Commonly used is low temperature weathering steel, which has a strong ability to resist low temperature corrosion. This type of steel SPA-C steel welding has a protective effect against corrosion.

Winning the battle against pollution is a major political task. The Department of Ecology and Environment of Henan Province has issued the "Precise and Scientific Implementation Plan for Special Actions for the Prevention and Control of Air Pollution in Autumn and Winter". The "Plan" clarified the province's environmental air quality "consolidation, optimization, and improvement" governance goals, and proposed the reduction of coal combustion, industrial pollution control, diesel truck pollution control, urban and rural non-point source pollution control, and pollution weather response. The 10 key tasks have laid the foundation for the improvement of air quality during the 14th Five-Year Plan.
