Many people don't understand the difference between stainless steel decorative tubes and product tubes. Why is the same specification, the price is so different? Now Rongxingyuan Xiaobian will let you know the difference between decorative tubes and product tubes.

The stainless steel decorative pipe is a stainless steel pipe made by welding a steel plate or a steel belt through a unit and a die. Let's take a look at the process flow of the stainless steel decorative tube with the small series.

Commonly used stainless steel decorative tubes on the market are polished tubes with a surface that is bright. So what factors affect the polishing of the stainless steel decorative tube surface?

Stainless steel decorative tubes , in general terms, are steel that is not easily rusted. The stainless steel tube has both rust and corrosion resistance due to the formation of a chromium-rich oxide film (passivation film) on its surface. This rust and corrosion resistance are relative. The test shows that the corrosion resistance of steel in the weak medium such as atmosphere and water and oxidizing medium such as nitric acid increases with the increase of chromium content in steel. When the chromium content reaches a certain percentage, the corrosion resistance of steel is abrupt. From rust to rust, from corrosion resistance to corrosion resistance.

What is LSAW pipe means LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold expansion carried out after welding.

Always in pipeline systems we met the material with NACE MR0175/ISO 15156 pipe or fittings, so do you really know what is the major differences between NACE carbon pipe and normal carbon steel pipe? And how is the cost for nace material?

Steel pipe pile is a type of steel piling material. It is usually referred to the carbon steel pipe manufactured in seamless or welded (SSAW or LSAW), used for supporting and stabilizing the foundation of a building. So a pipe pile is a structural construction material.

Fire sprinkler pipe and related fittings are generally made of carbon steel or ductile iron material and used to carry water or other liquid to connect firefighting equipment. It is also called fire protection pipe and fittings. According to the corresponding rules and standards, the fire pipeline need to be red painted, (or with red anti corrosion epoxy coating), the point is to separately with other pipeline system. Since the fire sprinkler pipe usually installed in a static position, it requires a high level and restrict quality control.

As we know ASTM A106 Grade B pipe is one of the most popular seamless steel pipes applied in different industries. Not only in pipeline systems like oil and gas, water, mineral slurry transmission, but also for boiler, construction, structural purposes.

Polyurethane direct buried seamless insulation pipe has become a mature advanced technology in developed countries. China's heating engineering technicians have passed this research to promote this technology to promote the development of domestic pipe network technology to a higher level. Polyurethane direct-buried insulation tube is made of high-performance polyether polyol composition and multiple methyl polyphenyl polyisocyanate as raw materials, and then chemically foamed. It is widely used in indoor and outdoor pipelines and central heating. Pipe, chemical, pharmaceutical industry pipelines and other insulation, cold preservation projects. Polyurethane polyurethane direct buried seamless insulation pipeshould pay attention to the installation and explanation:

Insulation steel pipe high-density polyethylene polyurethane insulation pipe, polyurethane direct-buried insulation pipe is widely used in liquid and gas transportation pipe network, chemical pipeline insulation engineering petroleum, chemical, centralized heating and heating network, central air-conditioning ventilation pipe, municipal engineering. The high temperature prefabricated direct buried thermal insulation pipe is a direct buried prefabricated thermal insulation pipe with good thermal insulation performance, safe and reliable, and low engineering cost. It effectively solves the problem of insulation, sliding lubrication and waterproofing of exposed pipe ends of 13O °C-6OO °C high temperature heat transfer prefabricated direct buried insulation pipe in urban central heating.

The prefabricated polyurethane direct buried thermal insulation pipe not only has the advanced technology and practical performance which are difficult to compare with the traditional trench and overhead laying pipeline, but also has significant social and economic benefits, and is also a powerful measure for heating energy saving. The adoption of direct buried heating pipeline technology indicates that the development of China's heating pipeline technology has entered a new starting point. With the further improvement and development of this advanced technology, it is imperative to directly replace the trench and overhead of the heating pipeline.

On November 12, the European Commission made a preliminary ruling on anti-dumping investigations on seamless steel pipe products originating in China, and decided to implement a six-month temporary anti-dumping measure. The head of the Trade Relief and Investigation Bureau of the Ministry of Commerce made a statement on this.

　　The proper selection and use of the electrode directly affects the chemical composition and performance of the weld, which is an important part of the preparation of large-diameter seamless steel pipe welding. Choosing the right electrode requires a comprehensive consideration of various factors, and sometimes it needs to be tested and verified before it can be finalized. The aspects to be considered are as follows: the performance requirements of the weld metal , the shape of the electrode, the rigidity and the position of the weld, the crack resistance of the weld metal, the processability, equipment and construction conditions, and economic rationality.

The difference between the size of SC and DN of galvanized steel pipe: 1.SC generally refers to the welded steel pipe , the language STEEL CONDUIT, is a shorthand for the material.

Galvanized pipe, also known as galvanized steel pipe, is divided into hot-dip galvanizing and electro-galvanizing. The hot-dip galvanizing layer is thick, with uniform coating, strong adhesion and long service life. The cost of electroplating is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipes.

The high-frequency welded pipes are divided into the following four types. The definitions, functions and standard codes are as follows:

Hot dip galvanized square tubes are steels used in hot dip galvanizing processes. This process is a maintenance of steel itself. The medium of steel is prone to oxidation problems, and the application of hot dip galvanizing technology can prevent oxidation of steel. A thick, dense layer of pure zinc masks the exterior of the steel, preventing contact with any solution and keeping the steel substrate from corrosion.

To talk about the centralized classification of galvanized square tubes, we first look at the production process, which can be divided into hot-dip galvanized square tubes and cold-galvanized square tubes. It is precisely because of the difference in the addition of these two galvanized square tubes that they have many different physical and chemical properties. In general they have many differences in strength, tolerance and mechanical function.

High-pressure boiler steel pipe: high-quality carbon structural steel, alloy structural steel and stainless heat-resistant steel seamless steel pipe used for steam boiler pipes mainly used for manufacturing high pressure and above. These boiler tubes work under high temperature and high pressure by the party.

It is a long strip of steel with a hollow section and no seams around it. Steel pipes have a hollow section and are used in large quantities as pipes for transporting fluids, such as pipes for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, the steel pipe is lighter in weight when it has the same bending and torsional strength. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycles. Shelf and steel scaffolding used in construction. The use of steel pipes to manufacture ring-shaped parts can improve material utilization, simplify manufacturing processes, save materials and processing man-hours, such as rolling bearing rings, jack sleeves, etc., and have been widely used in steel pipes. Steel pipes are also indispensable materials for various conventional weapons, and barrels, barrels, etc. are all made of steel pipes. Steel pipes can be divided into round pipes and shaped pipes according to the shape of the cross-sectional area. Since the area of the circle is the largest under the condition of equal circumference, more fluid can be transported by the circular tube. In addition, the circular section is subjected to a relatively uniform force when subjected to internal or external radial pressure, and therefore, most of the steel pipes are round pipes.
