ステンレス鋼の酸洗と不動態化

ステンレス鋼の酸洗と不動態化

Austenitic stainless steel parts, by welding, heat treatment, forging, and other high-temperature processing, the surface will produce a layer of oxide skin, which should be removed by pickling. Stainless steel passivation is generally associated with pickling; pickling must be passivated after forming a protective film, which can effectively extend the service life of the equipment. Process Flow Comparison of the effect before and after pickling: Pickling (1) Purpose Stainless steel in the chromium, nickel, and other elements can promote the metal in the heating conditions to generate dense oxide skin. It is a kind of spinel structure (FeO2, Cr2O3, or N1O2), and they are practically insoluble in a variety of […]

海辺の高腐食環境における防食に関する研究

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 […]

小さなレモンがステンレス製品を輝かせる

A sleek lemon can make stainless steel products shine and radiance, and the unique lemon aroma is also unmatched by the pungent smell of chemical cleaners. Everyone who has stainless steel appliances or products in their homes has no doubt the meaning of the name of the stainless steel. The term “stainless” in stainless steel creates a product made of this material that is completely stain-free and shiny at all times. But unfortunately, this is neither fact nor fact. Stainless steel products are corrosion resistant and easy to clean compared to most materials, but they do not mean that stainless steel products are “stainless” at all times and under any […]

パイプニップルとパイプカップリングの違いについて

The difference between pipe nipple and pipe coupling What is a pipe nipple? Pipe nipple is a length of straight pipe with male threads on both ends. It is one of the most popular category of pipe fittings. It is a connector or a coupling threaded on both ends. Pipe nipples are used to allow plumbing to be connected to a water heater or other plumbing. They are used to fit straight end hose or pipe. A combination of pipe nipples are recommended for low-pressure discharge and suction service for various compatible liquids and not for compressible products like air, nitrogen or steam.  The length of the pipe nipple is usually specified […]

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? 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.

What is a Heat Exchanger

Heat Exchanger is a unit through which heat is transferred from one fluid to another. The solution in the Heat Exchanger can be separated by preventing the direct contact of the liquids. The internal combustion engine is a good example of the Heat Exchanger as it regulates the coolant through radiator coils. Parallel flow, cross flow and counter flow are the three main categories of exchangers, which are divided on the basis of flow arrangement. The Heat Exchanger transfers heat from one place to another at different starting temperature. If the Heat Exchanger has only one phase then it is termed as Single Phase Heat Exchanger whereas if it has […]
