Steel Tube Manufacturer & Supplier in USA

What Is The Difference Between Seamless And Welded Steel Tubes?

The manufacturing method and the component structures of seamless and welded steel tubes are different. Semi-finished steel tubes are rolled from a solid billet and pierced by heating thus eliminating welded joints inside. This product offers a uniform and steady construction that boosts the integrity and the endurance of the structure. These tubes are common in applications that call for high-pressure capability, corrosion resistance, and smooth inner surface such as in the oil and gas industry.

But the other hand, welded steel pipes are produced by joining many steel pieces together using welding. This is achieved by means of application of heat and pressure to the edges of the steel pieces that melt to form a continuous tube. As for the welded tubes, they are more cost-effective and are normally used for those applications where the structural strength is not that vital than in seamless tubes. While they may have a slightly lesser strength in compare to seamless tubes, thanks to the development of the welding technology, the quality of welded tubes is now quite good, which makes them convenient for many different industrial and commercial applications.

What are the Different Types Of Steel Tubes?

Pipingprojects.us is a premium Steel Tube Manufacturers in USA. We manufacture wide range of Steel Tube using different materials and grades:

• Seamless Tubes: Welding is not required in seamless pipes. In this case, they are rather formed by drawing a solid billet through a piercing rod. The result is a smooth looking cylinder which is known for its consistence and often used in high pressure conditions.
• Welded Tubes: Welded tubes are produced by welding flat steel sheets or strips together, and a typical feature of welded tubes is a noticeable seam. These tubes offer a cost-effective solution and, among other industries, they are used in construction and general engineering.
• Electric Resistance Welded (ERW) Tubes: WER tubes are obtained by heating and joining the edges of steel strips using electrical resistance. This type of welding is widely used in many different industrial sectors because of its capability to make robust joints.
• Hot Finished Seamless (HFS) Tubes: The hot-finished seamless tubes are made by piercing a solid billet, elongation and the reduction of diameter at high temperatures. This technique guarantees a smooth tube with optimum properties and good compatibility with many industrial applications.

What Are The Different Type Of Testing That Steel Tube Undergoes?

Before our Steel Tube deliver to our clients it undergoes various types of testing such as Visual Inspection, Chemical Analysis, Mechanical Testing, etc. The main purpose of testing is to ensure that our clients recieve top quality Steel Tube with no compromise in quality.

Mechanical Testing: This involves assessing the mechanical properties of steel tubes, such as tensile strength, yield strength, elongation, and hardness. These tests help determine the tube's ability to withstand applied forces and ensure it meets specified performance criteria.

Chemical Analysis: Chemical testing is conducted to analyze the composition of the steel, checking for elements like carbon, sulfur, phosphorus, and other alloying elements. This ensures the steel meets the required chemical specifications for its intended use.

Dimensional Inspection: This involves verifying the dimensions and tolerances of the steel tubes to ensure they meet the specified requirements. This includes checking the outer diameter, wall thickness, length, and straightness.

Visual Inspection: Visual inspection is an essential yet crucial test where the surface of the steel tube is examined for defects, irregularities, or signs of damage. This can include checking for weld quality, surface finish, and overall appearance.
