People always confused about how to describe steel pipe dimensions (sizes) in correct ways, or how to clarify to seller what exactly pipe size we are going to purchase. In case any misunderstandings or a different size we purchased, that will be a big trouble.

ASTM A335 pipe (with Grade P9, P11, P22, P91 pipes) has been widely used in different industries for high temperature, high pressure services. According to market data, it is one of the most consumption alloy pipes in boiler industry, heat exchanger, power station, high and super high pressure vessels.

The drill pipe is a vital component in the drilling process, primarily responsible for transmitting torque and transporting drilling fluid. By gradually adding drill pipe sections, the wellbore is extended to the desired depth. Selecting the appropriate drill pipe size and length is crucial, as it directly affects drilling efficiency, operational costs, and safety.

The service life of oil casing and tubing is closely tied to the entire life cycle of an oil well, often determining how long the well can operate safely and efficiently. In oil and gas production, casing pipes are typically used once, cemented in place, and permanently left underground. Their longevity depends on multiple factors, including material quality, threaded connections, geological conditions, construction practices, and ongoing maintenance. In most cases, casing service life ranges between 15 and 30 years, though actual performance may vary significantly.

Galvanized steel pipe is widely used in plumbing, construction, and outdoor projects because of its excellent corrosion resistance. However, welding galvanized pipe requires extra care compared with standard steel pipe. The zinc coating that protects the pipe can release hazardous fumes when heated, and improper welding may compromise both the weld quality and the protective layer. This guide explains how to weld galvanized steel pipe safely and effectively.

In oil, gas, and geological exploration drilling, the drill string assembly plays a decisive role in ensuring drilling efficiency and wellbore quality. Two essential components within this system are the Heavy Weight Drill Pipe (HWDP) and the Drill Collar. While they may look somewhat similar, their structure, functions, and applications differ significantly. Understanding these differences helps engineers and drilling teams choose the right tool for the right job.

Pipe bending is a critical process in many industries, from construction and shipbuilding to oil & gas and manufacturing. One of the most important parameters to understand during this process is the bend radius. The bend radius directly affects pipe integrity, flow efficiency, and installation requirements.

ERW (Electric Resistance Welded) pipe is one of the most widely used steel pipes in modern industries. It is manufactured by rolling steel sheets or strips and welding them longitudinally using electric resistance. The result is a strong, cost-effective pipe with a smooth finish and uniform wall thickness. But what exactly is ERW pipe used for?

Schedule 80 steel pipe refers to a wall thickness classification defined by the American National Standards Institute (ANSI) and the American Society of Mechanical Engineers (ASME). The actual wall thickness of Schedule 80 pipe depends on its nominal pipe size (NPS) — the larger the diameter, the thicker the wall in absolute terms.

When it comes to steel pipes, corrosion resistance is always a key concern. One of the most commonly used methods to enhance durability is galvanization. Among the different galvanization techniques, pre-galvanized steel pipes stand out as a widely adopted solution in construction, infrastructure, and industrial projects.

The length of a steel casing pipe depends on its diameter, installation environment, and application requirements. While standard lengths are commonly used, specific projects may require customization. Choosing the right length is essential to ensure both installation efficiency and long-term performance.

In the high-stakes world of oil, gas, and water well exploration, safety and stability are the cornerstones of success. Central to achieving both is a critical steel tubular product known as casing pipe. While it may not be the pipe that transports oil or gas to the surface, its role is arguably more critical. As a steel pipe supplier, understanding the definitive purpose of casing is key to appreciating its immense value and serving the vital industries that depend on it.

In the vast landscape of industrial materials, few are as fundamental and ubiquitous as carbon steel plate. Renowned for its exceptional strength, durability, and versatility, it serves as the foundational material for countless applications that shape our modern world. From towering skyscrapers to essential machinery, carbon steel plate is the unsung hero supporting global progress. For us in the steel pipe industry, a deep understanding of this crucial material is key to appreciating market dynamics and serving our customers' needs effectively.

Galvanized steel pipes are essential in modern construction and industrial applications, known for their durability and corrosion resistance. Among them, the 424 galvanized steel pipe stands out for its reliable performance and broad utility across numerous industries. This article highlights its key features, typical applications, and manufacturing process.

Structural pipe is a type of steel pipe specifically manufactured and used for structural applications—not for transporting fluids or gases. Unlike standard piping used in plumbing or energy industries, structural pipe serves as a critical component in construction, support frameworks, and mechanical structures. Its key advantage lies in its strength, versatility, and availability in various sizes and grades to meet engineering requirements.

Traditional API casing threads (such as long round and partial trapezoidal threads) are not well-suited for the development of high-pressure gas fields, primarily due to limitations in air-tightness and tensile strength. To address these challenges, many manufacturers have developed proprietary premium connections with enhanced sealing and mechanical performance. Among them, several gas-tight special thread types have proven suitable for demanding gas field applications.

Galvanizing is a widely used anti-corrosion process in which a layer of zinc is applied to the surface of iron or steel pipes. This zinc coating acts as a protective barrier against corrosion by sacrificing itself to protect the underlying metal—a process known as cathodic protection. Zinc helps to shield the pipe from moisture and oxygen in the environment, preventing rust formation. Additionally, it provides UV protection, reducing the risk of degradation from sunlight exposure.In this article, we’ll explore the key advantages of galvanized pipes and outline common dimensional specifications.

In the world of steel pipe manufacturing, Electric Resistance Welded (ERW) and Double Submerged Arc Welded (DSAW) pipes are two widely used types of straight seam welded pipes. While both serve structural and fluid transport purposes, their production methods, performance characteristics, and application ranges differ significantly. Understanding the key differences between ERW and DSAW pipes is essential for selecting the right pipe for specific industrial needs.

Galvanized pipe, known for its corrosion resistance and durability, is widely used in plumbing, construction, and industrial applications. Whether you’re selecting a pipe for water supply, fence posts, or structural support, understanding how galvanized pipe is measured is essential for choosing the right size and ensuring compatibility with fittings and other components.In this blog, we’ll break down how galvanized pipe is measured, what measurement standards are used, and how to avoid common confusion when selecting pipe sizes.

Black steel pipe is a widely used type of carbon steel piping, named for its dark, iron-oxide coating that forms during the manufacturing process. Unlike galvanized pipe, black steel pipe is uncoated and untreated with any zinc or paint, which makes it suitable for specific industrial and structural applications.So, what exactly is black steel pipe used for? Let’s explore its most common applications and why it continues to be a top choice across various industries.
