15CrMoG high-pressure boiler tube knowledge provided by Chongqing Fengshuo Weiye
15CrMoG high-pressure boiler tubes, provided by Chongqing Fengshuo Weiye, are a type of alloy structural steel used in the production of seamless steel tubes. These tubes are widely applied in various high-pressure environments such as hydraulic supports, high-pressure gas cylinders, industrial boilers, fertilizer equipment, oil refining, automotive components, diesel engines, and hydraulic fittings. Their excellent mechanical properties and resistance to high temperatures make them ideal for demanding applications. The weight calculation formula for 15CrMoG high-pressure boiler tubes is: [(Outer Diameter - Wall Thickness) × Wall Thickness] × 0.02466 = Weight per meter (in kg). This formula helps engineers and technicians estimate the weight of the tubes during design and transportation planning. One of the unique features of 15CrMoG tubes is their application in hydrogen purification systems. At temperatures between 300°C and 500°C, when impure hydrogen is introduced into one side of the tube, it interacts with the palladium layer on the surface. Due to the electronic structure of palladium—specifically its lack of two 4d electrons—it can adsorb hydrogen molecules, forming unstable bonds. This reaction is reversible. Under the influence of palladium, hydrogen molecules are ionized into protons with a radius of approximately 1.5×10â»Â¹âµ meters. The lattice constant of palladium at 20°C is 3.88×10â»Â¹â° meters, allowing these protons to pass through the metal lattice. Once on the other side, the protons recombine with electrons to form pure hydrogen gas, which then exits the tube. Gases that do not dissociate remain trapped on the surface, ensuring high-purity hydrogen output. Understanding the properties and applications of 15CrMoG high-pressure boiler tubes is essential for engineers and professionals working in industries that require reliable and high-performance materials.

Tunnel Spear Bolt is classified under the special type of bolts that are known as structural bolts which can be produced in various grades, sizes and load capacities depending on their specific use. These spear tunnel Bolt are utilized to make transportation through undersea and underground tunnels possible by binding together a number of metal beams and posts which make up the tunnel`s frame.
