Technical Articles for Pipe Fitting

Due to the advantages of simple equipment, dense coating, controllable composition and thickness, and strong winding plating, electrodeposition coating technology has been widely used for modifying and protecting the inner walls of pipe fittings (especially special-shaped parts). However, compared...

3. Analysis of Stable Failure Causes According to the characteristics of failure in expansion joints, instability deformation mainly occurs due to the forces from the blind plate and shaft displacement. The factors causing instability in expansion joints are primarily defects in the joints themselves,...

Introduction During the operation of petrochemical pipelines, the combined influence of ambient temperature, fluid temperature, and pressure changes often causes vibrations and displacements, adversely affecting the safe operation of connected equipment and the sealing performance of the pipeline. Therefore,...

Based on the self-designed organic glass bend test section, this paper presents an erosion experiment of liquid-solid two-phase flow on a bend using the existing circulation pipeline to study the effect of flow rate on the erosion of the inner wall of the bend. 3.1 Experimental Technology and Steps...

Erosion often occurs during the development of oil and gas fields and is a major issue affecting their long-term safe production. Erosion can lead to thinning and perforation of equipment and pipeline wall materials, eventually causing equipment failure. By the end of 2017, the total mileage of China's...

1.1 Introduction The power industry is a crucial foundational industry in the development of the modern economy. Currently, the three main forms of power generation are thermal power, nuclear power, and hydropower. In China's power industry, thermal power generation accounts...

6. Machining, surfacing and product inspection According to the product size drawings and the marking process card, the branch pipe center, main pipe center, branch pipe height, and product length are clarified. The cutting size and groove processing allowance are calculated, and the cutting and sizing...

Elbows and reducers play a crucial role in the transportation of underwater oil and gas. These components are essential for ensuring the smooth flow of fluids through pipelines, especially in deep-sea environments where pressure and temperature conditions are extreme. Elbows are used to change the direction...

1. Introduction  As underwater oil and gas develop towards deep water, the seabed operating environment faced by underwater production facilities is becoming increasingly severe. The complexity of oil and gas components puts higher and higher requirements for strength and corrosion resistance on...

Reducers are a common pipe structure in the steam and water pipeline system of thermal power plants. They are used at the joints of pipes with different diameters. According to different structural types, they are mainly divided into concentric reducers and eccentric reducers. Eccentric reducers have...
