Product Introduction

Welded carbon steel piping is formed from an originally flat piece of carbon steel. The piece of carbon steel is rolled and welded creating a welded seam going long ways down your piece of carbon steel tubing or piping. The weld is formed by using a high energy source to melt the local metal together. Thus creating a weld bead when squeezed together. You will notices where the welded seam is the weld bead. This will be raised compared to the rest of the carbon steel pipe. You will find that some seams are manipulated to become more flush with the piping, while others are sold “as-weld” meaning they are left how they are welded with no further processing to the carbon steel.

About Us

Different Types of Carbon Steel

• Low-carbon steel with a carbon content of between 0.04% and 0.30% is the largest category of carbon steel.

Properties: High toughness; Low tensile strength; High weldability; Low cost; High ductility; Low hardness; High machinability.

• Medium carbon steel with typical carbon values between 0.31% and 0.60% and manganese content between 0.31% and 0.60%

Properties:Medium strength; Moderate toughness; Medium weldability; Medium ductility; Moderate machinability.

• High-carbon steels are often referred to as “carbon tool steels” and typically contain between 0.61% and 1.50% carbon.

Properties: High toughness; Low machinability; High strength; Moderate weldability; Low ductility.

Advantages of Welded Carbon Steel Pipe

Zhongao Metal provide quality welded steel pipes according to oversea buyers’ requirement and customization. Well, for the advantages of welded steel pipe, Compared with solid steels such as round bar steel (steel rod), welded steel tube has lighter weight when its bending and torsional strength keep the same. In addition, it is a kind of steel with economic section. Following concrete advantages,

▪ Welded steel pipes have high accuracy, uniform wall thickness and high brightness of inner and outer surface (Tips: steel pipe surface brightness depends on surface grade of the steel plate.)

▪ Its weight is only 1/5 of square steel because of welded steel tube with lighter weight.

▪ Welded steel pipe has corrosion resistance, acid, alkali, salt and atmospheric environment corrosion resistance, high temperature resistance, good impact resistance and fatigue resistance.

▪ Welded steel pipe has excellent mechanical properties and the machining is more easy.

We have our own Physical & Chemical Testing Center Lab to guarantee our product quality. Our test items & instrument fully meet international standards.

Applications of Welded Carbon Steel Pipe

Wide range of usage about welded steel tubing, for example, all-purpose welded steel pipe used for compressor stations, power plants, refineries, natural gas transportation and steam, vapour transportation. In addition, It is also widely used in manufacturing structural and mechanical spare parts like oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction. Welded steel tube can improve material utilization, simplify manufacturing process, save steel materials and processing time. It can be finished and processed as welding, bending and flanging.
