Comparison between hot rolled and galvanized square steel tubes

  Different production process would give clients various types of square steel pipe. Today, for this kind of ERW steel pipe , we will have a comparison for the hot rolled and galvanized.   Hot rolled square steel tubing: due to its special strength, durability and ability to withstand extreme temperatures, it is usually used for domestic and industrial applications. With the process of welded, formed and drilled, it has a wide range of application for customers.   Galvanized square steel tube: it is easy to weld, cut, form and machine. The galvanized coating also allows for improved corrosion resistance over other types of carbon steels. In addition, galvanized tubes are a lower cost alternative to steel to achieve rust free protection for up to 30 years, while maintaining comparable strength with a durable surface coating.

Three steel pipe standards comparison

  Different steel pipe, both seamless pipes and welded tube like ERW steel pipe , will be applied in various situations. There will be different steel pipeline’s standards in the pipe field for multifarious usage.   Thus, there are different demands for pipes. It is very important to know what's your application before ou inquiries. Here, we would like to compare three tubes from standard aspect.   API 5L: PSL 1and PSL 2 would be the normal type for this category. Whether seamless or welded type, API 5L can meet our demands with international standard requirements.   ASTM A53: Another popular steel pipe among engineering project. It contains from pipe, steel, black, hot-dipped and zinc-coated, welded and seamless. Generally speaking, customers will use them among mechanical and pressure applications.   EN10219: Used for cold formed welded structural hollow sections of non-alloy and fine grain steels, this type tube is also popular among clients.

Different standards lead to different applications of ERW steel tubes

  We are familiar ERW steel pipe due to its wide application all over the world nowadays. Today, our topic would focus on the different standards for this pipeline and its application according to various characters.   1. API 5L Line Pipe for oil and gas, and we can provide different categories here.   2. ASTM A53 standard specification for steel pipes. ASTM steel tube has multifarious standards and you can ask for detailed information if you are interested in this type.   3. Black and Hot-Dipped, Zinc-Coated Welded and Seamless. No matter welded or seamless steel pipe, it is not a big problem once you purchase here in our company.   4. EN10217 Welded steel tubes for pressure purposes. Technical delivery conditions. Talking about pressure, low, middle and high pressure transmission tubes, you can have a look here.   5. Non-alloy steel tubes with specified room temperature properties. Non-alloy or alloy steel pipeline is also in our production range.

Is seamless steel pipe better choice than welded tube?

  The answer would be uncertain. No matter the option for seamless steel pipe or welded type, the choice will rely on project’s application, because different specs and grades of steel pipe have unique characteristics.   Except price and other factors affecting the choice of pipelines, we will talk about the choice just from the application.   For welded tube, it would be popular when used for moving things like water and other low pressure products. If there is a water transportation system in a yard sprinkling, we will adopt this. Of course, structures like yard fences and more critical usage are also nice for using of welded pipe.   For seamless steel pipe, due to its special durable and reliable quality with the feature of no seam, seamless steel pipes might then be necessary for machinery, as the stronger steel lasts longer and is less susceptible to failure.    http://www.xysteelpipe.com/info/Is-seamless-steel-pipe-better-choice-than-welded-tube-1302-1.htm

Economic benefits of steel tubes

  As summer approaches, the weather becomes hotter. We bought an air conditioner in our dormitory. When the installer installing the air conditioner, I asked him “What kind of pipe do you use?”. “copper pipe”, he answered. “And what kind of pipe is the water pipe?”, “like ERW steel pipe .”   And then I find there are many things are made of metal pipes in our dormitory. Among them, steel pipes uses most. At that night, I think the question “If there is no steel pipe in the world”:   I know that in recent years, more and more enterprises at home and abroad have replaced seamless pipe with steel pipe. Because of steel pipe, it greatly reduces our purchasing cost and improves our economic benefit.   I know it would be difficult for us to build a building without steel pipes. Steel pipe is widely used in the construction industry. Steel pipe is used in large shopping malls, theaters, airports and bridges and so on.   When we drive a car, we need to use steel pipe to discharge car e...

Choose steel pipe according to its working pressure

  Short-distance and long distance pipeline, no matter seamless steel pipe for oil and gas transportation, or welded one for water transportation, would have great difference on choosing.   To some extent, working pressure and diameter would decide the pipeline’s design of framework technical parameters.   First of all, working pressure directly determines the number of pumping stations and compressor stations, steel consumption in the power station unit and piping.   Working pressure on the economy and security of the pipeline project is the first. Working pressure is an important part of the design of oil and gas pipelines, the technical and economic conditions of its great influence on the pipeline, the pipeline operating pressure is not too high; optimum working pressure gas pipeline and gas pipeline construction investment and operating costs related to; generally, the high pressure tends to work best value.

Special treatment for large diameter steel pipe

  If your customer has affection on large diameter steel pipe, no matter ERW steel pipe or LSAW type, you would figure out the advantages for it. Thus, you will finally figure out the special treatment for large diameter steel pipe.   In order to achieve the standards like API, we know that large diameter pipe would have strict production process. Thus, it can serve on the engineering project like bridge piling, underwater piling, piling high-rise buildings.   With its good adhesion, corrosion resistance, and other traits, we will make large diameter steel tube improve traffic and transportation efficiency, reduce delivery pressure loss.   Coating solvent-free is another character, no leaking substances, and thus will not contaminate the transmission medium, thus ensuring fluid purity and hygiene at -40 ℃ to +80 ℃ range can be used alternately hot and cold cycles, aging, no cracks, which can in cold areas such harsh environments.
