海辺の高腐食環境における防食に関する研究

Various equipment, pipelines, and other metal structures of anti-corrosion treatment can not only play the role of beautification and identification, at the same time, also relates to the long-term safe operation of these components; however, in the actual use of anticorrosion technology in the process of anti-corrosion treatment of finished products or will often appear rust phenomenon, especially in the seaside under the high corrosive environment of the situation is particularly prominent. Therefore, how to better deal with the corrosion of metal parts to ensure their safe operation is a technical difficulty. The article and the seaside high corrosion environment corrosion control problems are briefly analyzed. 0. Introduction Seaside corrosion […]

埋設型天然ガスパイプライン用ティーの故障解析

In order to analyze the cause of the fracture of a high-pressure gas pipeline tee, the material metallographic examination, mechanical property examination and micro fracture scanning electron microscope were used to analyze the crack. It was concluded that the tee was not normalized or recrystallized annealed, and the external load was the main cause of the fracture. A high-pressure gas pipeline directional crossing of the highway was completed after 2 years of use, due to traffic needs, the overpass was erected above the pipeline. The edge of the overpass foundation is about 0.5m from the tee setting, and the pipeline is about 0.6m above the foundation at the bottom of […]

大口径薄肉スリーブの研削方法の改善

Due to the poor rigidity of large-diameter thin-walled sleeve, it is difficult to control the clamping force in grinding, which affects the machining quality. In view of this situation, several improvement schemes are adopted to ensure the machining accuracy requirements and product quality. 1. Preface When grinding the inner and outer surfaces of the sleeve with large diameter and thin wall thickness (not more than 2mm), due to poor rigidity and difficult control of the clamping force during actual processing, the workpiece is often deformed due to excessive axial clamping force, which affects the machining accuracy or the workpiece is thrown out of the chuck due to poor clamping. To […]

ステンレス鋼管ベンドの製造工程

The production process of stainless steel pipe bend According to the different manufacturing methods, the stainless steel pipe bend can be divided into three types, namely, the bending pipe, the punching pipe and the welded pipe. Which can be divided into two types of bending bending and bending. When the stainless steel tube for bending the pipe along the longitudinal direction under pressure, leading to pipe wall thickness of the pipe is shortened, the lateral pipe subjected to tensile, elongation, wall thinning and tube; center without force, deformation will not occur. The cross section of stainless steel tube is changed from round to oval. Bend in the production of the need to […]

What is Pipe fitting

パイプ継手とは？

What is Pipe fitting? Pipe fitting is the operation of repairing or installing tubing or piping systems which convey gas, liquid, and solid materials occasionally. It also involves selecting and preparing tubing or pipe, joining it by several means and location and repairs of leaks. Fitters work with various tubing and pipe materials such as copper, aluminum, steel, plastic and iron. Pipe fitting is not referred to as plumbing although the two are related, but have separate trades. Stainless steel pipe fittings are made of stainless steel, so it is made of stainless steel pipe fitting, which contains: stainless steel elbow, stainless steel tee, stainless steel cross, stainless steel reducer, stainless steel pipe cap, […]

What are pipefittings?

What are pipefittings?

What are pipefittings? Pipefittings are general terms for components in the piping system that function as connection, control, direction change, split, seal, and support. According to the different processing methods, it is divided into four categories, namely, butt welding pipe fittings (both welded and non-welded), socket welding pipe fittings and threaded pipe fittings and flanged pipe fittings. Chinese name 管件 Uses Coupling, changing direction, diversion, sealing, support, etc. Application Petroleum industry; construction industry; chemical industry, etc. This is a long article, and I organize it into 6 chapters.

Destructive and No-destructive Testing of Butt Weld Pipe Fittings

Destructive and No-destructive Testing of Butt Weld Pipe Fittings Why and how often are butt weld pipe fittings tested ? Butt weld pipe fittings are tested to assure conformity with standards and performance in their applications. Standard, commodity butt weld pipe fittings are tested by sampling during manufacturing process, with both destructive and non-destructive approaches. Custom-made butt weld pipe fittings are regularly tested during manufacturing process with non-destructive approaches, as required for the application or as specified by end-users. What is the difference between a destructive and a non-destructive test ? After a destructive test, fittings can no longer be used in the field, because they were bent, pulled or abused […]

Manufacturing Process of Butt Weld Pipe Fittings

Manufacturing Process of Butt Weld Pipe Fittings What is the difference between a manufacturer and a supplier of butt weld pipe fittings ? Manufacturers own machines, presses and equipment to actually make butt weld pipe fittings from pipe or plate. Suppliers are intermediaries between manufacturers and end-users: suppliers can be wholesalers, distributors, EPCs, … In some cases, end-users need to speak directly to manufacturers to get the fittings they need when they need them. Can fitting manufacturers in North America and Europe compete with low-labor-cost countries ? Butt weld pipe fittings are used in the most demanding applications: oil & gas, nuclear, chemicals, … A butt weld pipe fitting looks […]

Materials of Butt Weld Pipe Fittings

Materials of Butt Weld Pipe Fittings Why do manufacturers offer such a large variety of metals and materials ? Pipes and fittings are used in many applications and many industries that have widely different operating conditions. To reach best performance (resistance to various types of corrosive fluids, operating temperature, …) at acceptable costs, many metals have found unique niche applications in fittings. Why choose a specific material, or grade, or schedule for a fitting ? Choice of material or grade or schedule is not made by distributors or by fitting manufacturers, but by engineers who design pipelines or systems based on performance requirements and acceptable costs. Engineers take into account […]
