What Is a Diaphragm Coupling? A coupling is a mechanical component used to connect two shafts in different machines or mechanisms so that they can rotate together and transmit torque. In many power transmission systems, the coupling does more than simply transfer rotational power. Depending on its design,...

1. Introduction: Comparing 430 and 304 Stainless Steel Stainless steel is one of the most widely used metal materials in pipe industries due to its excellent durability, corrosion resistance, and attractive appearance. Among various stainless steel grades, 430 stainless steel and 304 stainless steel...

1. Introduction: The Rising Role of Aluminum 3003 Coil in New Energy The global energy landscape is undergoing a fundamental transformation as countries and industries accelerate their transition toward cleaner and more sustainable energy solutions. Driven by ambitious carbon reduction targets and the...

Abstract: Based on the operating principle of the magnetic leakage detector (MLD), this paper clarifies the signal identification characteristics associated with pipe dents and bends. Using actual inspection data from a 711 mm natural gas pipeline as a case study, the signal characteristics of pipe...

Abstract This study investigates abnormally high local hardness and metallographic microstructure observed in a high-temperature reheat steam pipeline elbow fabricated from SA335 P91 steel in a power plant. The chemical composition, wall thickness, hardness, and microstructure of the elbow...

5.1.1 Evolution of the Flow Field in the Bend The influence of flow velocity on the flow field characteristics within the pipe bend was investigated while the bend diameter ratio and solid particle concentration were kept constant. A bend diameter ratio of R/D = 3.5 and a solid particle concentration...

Abstract: This study investigates pipe perforation and leakage caused by erosion from ammonium chloride crystallization in the top circulation system of heavy-oil catalytic cracking units. By analyzing the erosion and wear behavior of salt crystallization, areas prone to perforation are identified,...

Abstract: This study investigates the formation of the σ phase in austenitic heat-resistant steel pipe joints used in power plant boilers. Results show that different morphologies of the σ phase precipitate in austenitic steel joints after high-temperature aging. The formation...

Abstract: During a scheduled inspection at a petrochemical plant, pitting corrosion was detected in the base material of a TP304 ethylene pipeline elbow. To determine the cause and develop effective countermeasures, a comprehensive analysis was conducted, including evaluation of the base material’s...

Abstract In a thermal power plant project, small-diameter serpentine heat exchanger tubes were fabricated from 20G steel with dimensions of Ø25 × 3 mm, a bend angle of 180°, and a bend radius of 27.2 mm. The tubes were formed using a CNC top-roll tube bender. However, during the...

Abstract: A numerical simulation study of pipe cap hot forming was conducted using DEFORM-3D finite element analysis software to determine the optimal heating temperature and dimensions of the pipe cap blank. The results offer valuable guidance for the design and manufacturing of pipe caps. Pipe...

Abstract: A leakage occurred in the elbow section of the sampling pipeline connected to the liquid level gauge of a high-temperature reheat steam drain tank in a thermal power plant during normal operation. The root cause of the elbow failure was investigated using macroscopic observation, chemical...
