High-pressure seamless steel pipes are actually high-pressure boiler steel pipes. Because they are commonly used in high-temperature, high-pressure boilers, they are also called boiler steel pipes. Although the names differ, they are essentially the same type of pipe, and both fall under the categor

15CrMoG high-pressure alloy steel pipe is a seamless steel pipe made of pearlitic heat-resistant steel. It possesses the typical properties of high-pressure alloy steel pipes and is widely used in industries such as power and petrochemicals that require high-temperature and high-pressure environment

First, what are the key points of the pretreatment process before polishing precision steel pipe fittings? Pretreatment is the prerequisite for ensuring the polishing effect and avoiding secondary damage. The core objective is to thoroughly remove surface impurities and repair basic defects, laying

First, what is the process principle of pickling and passivating seamless steel pipes?(1) Pickling process: Pickling mainly utilizes acid solutions (such as hydrochloric acid, sulfuric acid, nitric acid, etc.) to chemically react with rust, oxide scale, and other impurities on the surface of seamles
