ERW Steel Pipe

    Application:     Galvanized bobbin is specially used for threading and wire     Galvanized steel pipe is used for water gas pipeline     Material:     Galvanized steel pipe and galvanized wire pipe are divided into two materials: hot-dip galvanized and electrogalvanized     Performance:     Galvanized wire pipe is a kind of steel pipe. The galvanized wire tube can be subdivided into two types: whole galvanized inside and outside and outer galvanized. The normal galvanized wire pipe refers to the steel pipe inside the zinc, which is dedicated to the threading pipe.     Galvanized steel pipe is a welded steel pipe with hot dip or electrogalvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas,...

    ERW steel pipe (ERW steel pipe) is generally used as a wire sleeve in the power industry. Performance characteristics: 100% ultrasonic testing of the base material to ensure the inherent quality of the pipe body; there is no unwinding-disc shearing process , The base material has less pits and scratches; the finished pipe after stress relief basically has no residual stress; the weld is short, and the probability of defects is small; the moist sour natural gas can be transported conditionally; after the diameter is expanded, the geometry of the steel pipe High dimensional accuracy; welding is performed in a straight line in the horizontal position after the molding is completed. Therefore, the control of staggered edges, slits, and pipe diameter circumference is good, and the welding quality is excellent.

    Corrosion of oil casing is related to factors such as partial pressure of corrosive gas, ambient temperature, water content, salinity, flow rate, pH value and so on. So what are the anti-corrosion processes of the oil casing pipe? Let ’s take a brief look:     1. Cement sealing anticorrosion skills     In the earliest period, after analysis, it was thought that the key point of casing damage was due to the inability of the cement to return to high, the formation of the external water layer was not completely sealed, and the formation of corrosive gases in the water layer corroded the surface of the casing to form corrosion. Therefore, in the 1980s, it was proposed to increase the cement back to increase the corrosion resistance of the casing. After this technique, the casing corrosion level has been reduced, but the casing corrosion has not been completely prevented, so the casing anti-corrosion function has not been raised from the spring.  ...

    Stainless steel is durable, low maintenance and can stay looking great for many years, but it still needs to be looked after.     The basics of stainless steel maintenance     1.Apply pickling paste – if you have a small, difficult surface, you can use pickling paste or gels for brush pickling of weld seams. It adheres well and lasts a long time.     2.Apply pickling spray – the spray is better for larger surfaces of most stainless steel grades; it is able to reach even the most difficult sections due to its thixotropic consistency.     3.Use a pickling bath – if you have smaller stainless steel objects like pipe sections that need rejuvenating then pickling bath fluid allows you to fully immerse them for maximum cleaning effect.     4.Apply cleaning agents – for superficial rust, grease and lime deposits that can occasionally appear on any stainless steel surface, you can use cleaning agents to restore the surfa...

    With the continuous development of society, alloy steel pipe is applied to the more and more field, whether it is in the water, oil or gas and other fields are applied to the alloy steel pipe, alloy steel pipe prospects is very broad, what is the comparative advantage compared to other steel pipes? Here to understand the advantages of alloy steel pipe     1.environmental protection. Environmental protection has been the theme of social development of all walks of life, the biggest advantage is to achieve 100% recovery, which compared with other steel is naturally superior, will not cause material waste.     2.Wide application scope, it is widely used in petroleum, gas and other industries, for this important energy, the requirements of the pipeline is also very strict, in the power plant, nuclear power, high pressure boilers and other industries have also been widely used.     3.Save easily. General steel pipe material is easy to rust i...
