This article will briefly introduce perforated and slotted casing and tubing.

The API standard, short for the American Petroleum Institute, is one of the key production standards for oil pipeline steel pipes.Here's an overview of casing and tubing grading in API 5CT.

OCTG (Oil Country Tubular Goods) casing and tubing are widely used in the steel industry. However, these materials often face the issue of decarburization. To prevent decarburization in OCTG casing and tubing, two primary methods can be employed.

API oil casing is a steel pipe used to support the walls of oil and gas wells, ensuring the proper operation of the well during drilling and after completion. This article will briefly introduce APl oil casing hydrostatic pressure test.

The production process of welded steel pipes involves forming steel sheets or strips into the desired cross-sectional shape using straight press rolls or helical methods, and then welding them together using heat, pressure, or other methods. As a result, defects in welded steel pipes can be categorized into two main types: base material defects and weld defects.

This article will briefly introduce ERW oil casing application and market analysis.

This article will briefly introduce the detection methods for industrial oil casing.

Batch number and heat number are essential identifiers in seamless steel pipe production.This article will talk about difference between seamless steel pipe heat number and batch number.

Large-diameter 3PE anti-corrosion steel pipes are renowned for their robust anti-corrosion properties and are extensively utilized in a variety of projects. This article delves into the details of large-diameter 3PE anti-corrosion steel pipes.

Large-diameter straight seam submerged arc welded (LSAW) pipes are widely favored for major oil and gas pipeline projects globally due to their thick walls, high-quality materials, and stable processing. The weld seams and heat-affected zones of these pipes are particularly prone to various defects. This article outlines key welding quality control measures for LSAW pipes to mitigate these issues.

The heat treatment process is crucial in enhancing the mechanical properties, corrosion resistance, and microstructure of stainless steel pipes, making it an essential step in both their manufacturing and application. The type of stainless steel dictates the appropriate heat treatment procedures. Here are some common heat treatment processes for various stainless steel pipes.

Q345B steel pipe is a common structural steel pipe, and its mechanical property index is one of the important standards to evaluate its quality. This article will introduce the mechanical property index of Q345B seamless steel pipe, including tensile strength, yield strength, elongation and impact toughness.

Full range of line pipes of superior quality, including those of high strength, high toughness, homogeneous material and corrosion resistance, for various services such as onshore, offshore, shallow water and deep water, non-sour and sour services.

ASTM A335 specification covers seamless ferritic alloy-steel pipe for high-temperature service. The pipe shall be suitable for bending, flanging, and similar forming operations, and for fusion welding. Grade P2 and P12 steel pipes shall be made by coarse-grain melting practice. The steel material shall conform to chemical composition, tensile property, and hardness requirements. Each length of pipe shall be subjected to the hydrostatic test. Also, each pipe shall be examined by a non-destructive examination method in accordance to the required practices. The range of pipe sizes that may be examined by each method shall be subjected to the limitations in the scope of the respective practices. The different mechanical test requirements for pipes, namely, transverse or longitudinal tension test, flattening test, and hardness or bend test are presented.

Seamless steel pipe is a high-strength, high-pressure steel pipe that is often used in pipeline systems for transporting gases, liquids, solids and other media. Seamless steel pipes are produced through cold/hot rolling and drawing processes. They have smooth surfaces, smooth inner and outer walls, high dimensional accuracy, and good corrosion resistance and mechanical properties. Therefore, seamless steel pipes are indispensable in some situations where high pressure and high flow are required.

Square steel pipe refers to a steel pipe with a square or rectangular cross-section. It can be divided into many types according to different manufacturing processes and materials. Common square tube steels include hot-rolled square tubes, cold-rolled square tubes, galvanized square tubes, etc. These different types of square tube steel have different physical properties and uses, but all offer excellent strength and corrosion resistance.

ASTM A179 Cold Drawn Seamless Carbon Steel Tube are manufactured in cold-drawn seamless, material in low carbon steel, sizes up to 3”, for heat exchanger and condenser.

In recent years, with the rapid development of the automobile industry, precision seamless steel pipes, as a high-quality steel pipe material, have also been widely used in this industry. This article will elaborate on the application and development of precision seamless steel pipes in the automotive industry.

Steel beams and profiled steel plates are both steel products, the difference lies in their different production processes and uses. Steel beam is a kind of steel with I-shaped cross-section, which is widely used in the fields of construction and bridge. Pressure plate is a kind of steel plate after pressing and molding, used in steel structure, industrial equipment and warehouses and other fields.

The classification of pipeline pressure levels refers to dividing the pipeline pressure levels into high pressure, medium pressure, low pressure and other levels according to the pressure that the pipeline must bear during work.
