Structural tubes are steel pipes primarily used to manufacture various architectural structures, mechanical components, and supporting elements. Their core function is to serve as the “skeleton,” bearing loads, transmitting forces, and maintaining the structural stability and shape of the overall structure.

A fluid pipe, as its name suggests, is a pipeline primarily used for transporting fluids. It is distinguished from structural pipes, which are mainly used for manufacturing mechanical structures, load-bearing supports, and the like.
Alloy steel pipe is a type of steel pipe made by deliberately adding one or more alloying elements—such as chromium, molybdenum, nickel, manganese, silicon, vanadium, and titanium—to carbon steel.

Oil tubing (also known as oil-specific tubing) is a general term for all steel pipes used in oil and natural gas drilling and production operations. It forms the “skeleton” and “blood vessels” of an oil well, and its quality directly affects the safety, efficiency, and cost of drilling operations.
Pipeline pipes are a general term for steel pipes specifically designed for transporting fluids such as oil, gas, and water. They are the core material used in constructing long-distance energy transportation networks (pipeline systems).

Large-diameter welded steel pipe
A straight-seam welded pipe is a steel pipe made from steel plates or strips as raw materials. Using a straight-seam forming process, the weld seam is created as a straight line parallel to the pipe’s axis, and then the pipe is welded together using various welding methods.

Helical welded pipe, formally known as helically submerged arc-welded pipe, is a type of steel pipe produced by rolling low-carbon carbon structural steel or low-alloy structural steel strips into a pipe blank at a specific helical angle (known as the forming angle), and then welding the pipe seam to complete the pipe.

“Coiled pipe” is not a standard product name for steel pipes; rather, it’s a colloquial term used to describe either a manufacturing process or a specific product form. It carries two main meanings:
As a raw material: It refers to steel coils—steel plates or strips that have been rolled and then coiled into cylindrical shapes. These coils serve as the raw material for manufacturing welded pipes.
As a finished product: It refers to steel pipes that are produced by rolling and shaping steel plates or strips into cylindrical forms and then welding them together. In this context, “coiled pipe” typically refers specifically to spiral-welded pipes.

Straight-seam rectangular tube
Seamless square and rectangular tubes are steel pipes with square or rectangular cross-sections, manufactured by special processes such as cold drawing or hot extrusion, using seamless round tubes as the billet. Their most distinctive feature is that they are entirely free of welds while retaining the characteristic cross-sectional shape of square and rectangular tubes.

“Right-angle square tube” is a colloquial, emphatic term used to refer to square steel tubing—it’s not a standard academic term. It specifically refers to steel tubes whose corners are precisely at 90-degree right angles, with straight edges and a square cross-section.

Special-shaped tubes are a general term for steel pipes (or other metal pipes) whose cross-sectional shapes are not circular. They are distinguished from conventional “circular tubes.” Simply put, any pipe that is not circular can be referred to as a special-shaped tube. These tubes are produced by employing specific rolling, drawing, or extrusion processes to transform round tubes or billets into complex shapes as required.

Stainless steel pipe is a long, hollow steel bar whose primary characteristics are its resistance to rust and corrosion. The secret behind its “rust resistance” lies in its high chromium (Cr) content—typically no less than 10.5%. When chromium comes into contact with air, it forms an extremely thin, strong, and dense chromium-rich oxide film (passivation film) on the steel’s surface. This film effectively prevents further penetration of oxygen atoms, thereby conferring the steel with excellent corrosion resistance.
