As a high-performance, multi-purpose pipe in the industrial field, ASME SA312 TP321 stainless steel welded steel pipes play an important role in many industries such as petroleum, chemical, nuclear energy, aerospace, and food processing due to their unique material properties and wide application sc

1. Implementation standards of X80Q seamless steel pipes; API SPEC 5L pipeline steel pipe specifications, GB/T9711 steel pipes for pipeline transportation systems in the petroleum and natural gas industry 2. Chemical composition of X80Q seamless steel pipes: carbon: ≤0.18, silicon: ≤0.45, manganese

Large-diameter epoxy coal tar anti-corrosion steel pipes are made of two-component room-temperature curing paint, and the surface of the steel pipe is reinforced with glass cloth as a coating to prevent corrosion. It is used for the outer wall anti-corrosion of buried or underwater oil, gas, wate

Annealing is to heat the cold-rolled precision bright seamless steel pipe to an appropriate temperature, use different holding times according to the material and workpiece size, and then slowly cool it. The purpose is to make the internal structure of the metal reach or approach a state of equilibr

First, details of ASTM A312 straight seam stainless steel pipes Stainless steel welded pipes: Stainless steel welded pipes are also called welded pipes. They are made of steel plates or strips that are welded after curling and forming. They are generally 6 meters long. Welded steel pipes have simpl

1. 15crmog high-pressure alloy steel pipe unit equipment: 5 LG20 finishing mills, 4 LG60 finishing mills, 3 LG80 finishing mills, 3 three-roller finishing mills (production range 12-219*1-30mm, tolerance +-0.025mm), 7 cold drawing machines (drawing machine stroke up to 12 meters, drawing force up to

As an important alloy steel pipe, 15CrMo welded pipe is widely used in industrial fields such as petroleum, chemical industry, electric power, boiler, etc. This material has become one of the preferred materials for pipeline systems under high temperature and high pressure environments with its exce

First, quality control and testing of welded steel pipes: Quality control measures in the production process of welded steel pipes are important steps to ensure that the products meet the standard requirements. These measures are mainly concentrated in the selection of raw materials, production pro

10# seamless steel pipe, a seemingly ordinary but charming metal material, has become an indispensable and important role in industrial development with its unique performance and wide application fields. Among many seamless steel pipes, 10# seamless steel pipe has won the favor of the market with i

First, what are the characteristics of thick-walled stainless steel seamless pipes? Stainless steel thick-walled pipes are common thick-walled pipes with a wide range of industrial applications. Since stainless steel thick walls have good pressure-bearing and corrosion-resistant properties, they ha

With the continuous development of science and technology, the functions of various equipment, instruments, and electrical appliances are constantly upgrading. As a universal corrosion-resistant metal, stainless steel pipes have a very wide range of applications. Now many industries require non-magn

Thick-walled steel pipes require daily maintenance during use: Thick-walled steel pipes are widely used steel varieties. It directly affects economic benefits and personnel lives. Countries around the world attach great importance to the inspection of thick-walled steel pipes and use various non-de

In the fields of construction and industry, the choice of steel pipe often affects the quality and safety of the project. Galvanized steel pipe and stainless steel pipe are two common steel materials, each with excellent characteristics. The comparison of their strength has become a key factor in ma

1. Process the two plate edges into the required form at one time. Steel plate milling machine: machine the two sides of the plate material used for pipe making, and make the parallelism of the two plate edges reach the specified tolerance range, in preparation for manufacturing high-precision steel

Horizontal fixed welding of thick-walled stainless steel pipes: Stainless steel pipes are a kind of hollow long steel strips, that are widely used as pipelines for conveying fluids, such as oil, natural gas, water, coal gas, steam, etc. Stainless steel pipes are light in weight when the bending and

First, pre-welding of straight seam steel pipes: Pre-welding includes joints and welds. 1. The joint (also known as the forming seam) has no misalignment or the misalignment is less than the specified value. Generally, the misalignment is ≤8% of the plate thickness, and the maximum is no more than

First, the properties of high-frequency welded steel pipe and straight seam welded steel pipe are different. 1. High-frequency welded steel pipe: After the hot-rolled coil is formed by the forming machine, the skin effect and proximity effect of the high-frequency current are used to heat and melt

Galvanized steel pipes have the dual advantages of corrosion resistance and long service life, and the price is relatively low, so now its usage rate is getting higher and higher, but some users are not careful when welding galvanized pipes, which leads to some unnecessary troubles. So what problems
