  • Why some stainless steel pipes need to be degreased

    We all know that when stainless steel pipes leave the factory, they need to be pickled and passivated. However, sometimes users encounter re-degreasing treatment for pipelines? As far as the pipeline is concerned, the more reasonable degreasing should be completed on-site, that is, after the pipeline is completely installed, the degreasing treatment should be carried out in the entire pipeline system. Generally, manufacturers will not be allowed to perform degreasing treatment. So, what exactly is required for manufacturers to degrease pipes? With the increasing level of industrialization in my country and the vigorous development of petrochemical, natural gas, medical equipment, instrumentation, aviation, aerospace, and other industrial projects, the requirements for stainless steel pipe technology are becoming higher and higher. For…

  • Stainless steel water pipes are so popular in the international market, why?

    As early as more than a decade ago, some developed countries such as the United States, Europe, and Japan have abandoned traditional pipes such as galvanized steel pipes, plastic pipes, and copper pipes and turned to stainless steel water pipes. The use of stainless steel water pipes is becoming a global development application. Now stainless steel has become the best hydropower installation material on the world home decoration market. In 1980, Japan formulated industrial standards (JIS g 3448-stainless steel pipes for general piping), and in 1982, the Japan Water Works Association formulated jwwa g 115-stainless steel water pipes for water supply and jwwa g 116-stainless steel water pipe joints for tap water, and subsequently formulated Stainless steel bellows standard. In…

  • What is the maintenance method of stainless steel flanges?

    Many people should know the stainless steel flange, in fact, it is just a component. At the junction of the pipe and the pipe, use it to connect the two parts. These parts are very simple and easy to understand, but even in such a small part, the things behind it are very learned. What we should learn is how to maintain these components. First of all, when welding stainless steel flanges, we only want to prevent corrosion of the cover. In fact, the welding current should not be too large in order to cool down faster, which is also a better method of operation. Secondly, when using stainless steel flanges, appropriate stabilizing elements should be added to the stainless…

  • Explain how stainless steel flanges connect pipes

    Stainless steel flanges make it easy, fast and safe to install piping systems in various mechanical, industrial and marine applications. These accessories are made of highly corrosion-resistant 316 stainless steel and provide various O-ring seals, making them suitable for a variety of applications, such as HVAC, piping, municipal and industrial installations, the following to explain how the stainless steel flange is connected Pipelined, Stainless steel flanges are most commonly used in pipeline engineering. Pipe flanges are usually hard. Most of them are quenched and therefore usually resistant. Therefore, they are ideal for use in pipeline applications. The hardness of stainless steel flanges is usually 30. Normally, stainless steel flanges are quenched because their chromium content is 0.1% to 0.5% (stainless…

  • Briefly introduce the characteristics of stainless steel flanges

    We are a supplier specializing in the research and development of fluid pipeline technology. We produce, supply and export all kinds of high-quality pipes and fittings. We are praised by customers for its dimensional accuracy, precise function and durability. We provide the same customized size and shape to our respected customers. Let’s talk about the characteristics of stainless steel flanges. Flanges (also called flanges) are parts of pipes and pipes connected to each other. It is connected to the end of the pipe. There are holes in the flange, which can wear the bolts to make the two flanges tightly connected. Flange fittings are pipes with flanges (flanges or platforms) that can be cast, threaded or welded. Flanges (joints) are…

  • There are three types of stainless steel pipe fittings

    We are a company specializing in the design and manufacture of stainless steel fittings, stainless steel elbows, stainless steel tees and stainless steel flanges. Today, I will introduce the three types of stainless steel pipe fittings. Stainless steel pipe fittings are usually connected in three ways: butt welding, socket type and snap type: 1. Socket welding The pipe is inserted into the pipe socket part of the pipe, and then the pipe is argon arc welded along the edge of the pipe. It is the most commonly used connection method for stainless steel pipe fittings and the most reliable and stable connection method. 2. Butt welding Stainless steel pipes and fittings are welded by argon arc welding along the butt…

  • What is a stainless steel elbow?

    The stainless steel elbow is a pipe fitting that changes the direction of the pipeline. Stainless steel elbow is an elbow made of stainless steel as the main raw material. Stainless steel elbows are generally distinguished from carbon steel elbows. Their main difference lies in the different materials, which show various characteristics. Classification: According to the angle of the elbow, there are generally three types of stainless steel elbows, including 45-degree angle, 90-degree angle, and 180-degree angle. These three are the most common specifications of stainless steel elbows, which are more popular. Features: The biggest feature of the stainless steel elbow is that it is not easily corroded and rusted, so the service life is longer. Stainless steel itself is…

  • Introduction of the difference between 304 stainless steel and 316 stainless steel

    First, although there is not much difference in appearance between 304 stainless steel and 316 stainless steel, friends can distinguish the difference between the two in terms of composition. 316 stainless steel contains Mo, so that 316 stainless steel is much better in high temperature resistance than 304 stainless steel. If the building needs to be built in a high temperature environment, most design engineers will choose 316 stainless steel, so that it can be better The stability of the product. Second, 304 stainless steel and 316 stainless steel also have obvious differences in terms of grades. For example, the grade of 304 stainless steel is 0Cr18Ni9, while the grade of 316 stainless steel is 0Cr17Ni12Mo2. When buying, you can…
