The role of channel steel in engineering is multifaceted. As a commonly used structural material, channel steel is widely used in construction, bridges, machinery and equipment, ships, and other fields. It has the following important functions: 1. Structural support: Channel steel can be used for

The national standard for galvanized steel pipes has very strict quality control requirements, which are mainly reflected in the following aspects: 1. Appearance quality: The surface of the galvanized steel pipe should be flat and smooth, without defects such as cracks, pitting, oxide scale, oil

1. Surface treatment of steel pipe. The inner and outer surfaces of the steel pipe are shot blasted by shot blasting equipment, and the treatment reaches the Sa2.5 level requirements stipulated in the GB8923-1998 standard. After shot blasting, the vacuum adsorption equipment is purged, the cleanli

Hot-dip galvanized steel pipe specifications and models refer to the specific size and model identification of hot-dip galvanized steel pipes during the production and sales process. They are crucial to the selection, application, and installation of steel pipes. A hot-dip galvanized steel pipe is a

N80a steel pipe is a steel pipe material widely used in the field of oil drilling. It belongs to steel grade N80, has excellent performance and adaptability, and can meet the complex oil well environment and high strength requirements. First. Characteristics of N80a steel pipe. N80a steel pipe i

First, the metallurgical properties of the materials The raw material for spiral welded steel pipe production is a hot-rolled coil plate, while the straight seam welded steel pipe is made of steel plate sockets. The weight of the alloy contained in the coiled plate is less than that of the steel pl

1. Reasons for uneven anti-corrosion thickness of industrial 3PE anti-corrosion steel pipes The industry standard SY/T0413-2002 does not stipulate the uniformity of thickness. It stipulates the low thickness value of the coating but requires that the low thickness value of the coating cannot be low

Large diameter thick wall seamless steel pipes are mainly reflected in: 1. Large diameter: It is generally believed that seamless steel pipes with diameters above 219 are large-diameter seamless steel pipes, those with diameters less than 76 are small-diameter seamless steel pipes, and those in t

Seamless steel pipe anti-corrosion: ensuring high quality and corrosion resistance. Seamless steel pipes are increasingly used in the storage, processing, and transportation systems of various corrosive media. The requirements for corrosion resistance are getting higher and higher. How to improve th

304 stainless steel is an austenitic stainless steel and is in principle a non-magnetic product. However, during actual production and use, it may be found that 304 stainless steel has a certain weak magnetism. This is mainly due to the following factors: 1. Phase transformation during processing

Stainless steel, as a common metal material, is widely used in many fields because of its excellent corrosion resistance, heat resistance, and mechanical properties. Among them, 316L stainless steel pipe material has attracted much attention for its unique performance and wide range of application s

Large-diameter spiral steel pipes and large-diameter straight seam steel pipes are both types of welded steel pipes. They play an important role in national production and life. Large-diameter spiral steel pipes and large-diameter straight seam steel pipes have many differences due to different prod

Large-diameter spiral welded steel pipe is a type of steel pipe that has been widely used in recent years. Its main features are large diameter, high strength, and suitable for long-distance transportation and high-pressure medium transportation. First, spiral welding technology Large-diameter

Coating anti-corrosion is a uniform and dense coating formed on the surface of rust-removed metal pipes. The coating can isolate it from various corrosive media. Steel pipe anti-corrosion coatings increasingly use composite materials or composite structures. These materials and structures must have

In the steel industry, steel pipes, as an important basic material, are widely used in construction, machinery, chemical industry, and other fields. The alkali cleaning process of steel pipes, as a key link in the surface treatment of steel pipes, is of great significance for improving the anti-corr

Before working on the steel bending pipe, you must first calculate the unfolded length of the steel bending pipe section and mark the starting point of the bending so that the correct semi-finished product can be obtained after bending. First, the calculation of 90° steel bending pipe 90° steel

Stainless steel is a special alloy steel with excellent corrosion resistance and can resist the erosion of most chemical media, including acids, alkalis, salts, etc. This corrosion resistance is mainly due to the addition of chromium to stainless steel. Chromium can form a dense oxide protective fil

Carbon steel pipe is a commonly used industrial pipe, which is widely used in construction, manufacturing, and other fields due to its low price and high strength. However, carbon steel pipes are prone to rust problems, which will affect their service life and aesthetics if not treated in time. So,
