Seamless Steel Pipe

Carbon steel seamless pipes are widely used. Seamless steel pipes for general use are rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with large output, and are mainly used as pipes or structural parts for conveying fluids. Supply is divided into three types according to different purposes: A. supply according to chemical composition and machinery performance; B. according to the mechanical performance supply; C. according to the water pressure test supply. Steel pipes supplied according to categories A and B, if used to withstand liquid pressure, shall also be subjected to hydraulic pressure test. Special purpose seamless pipes. There are many kinds of seamless pipes for boilers, chemical power, geological seamless steel pipes and petroleum seamless pipes. Seamless steel pipes have a hollow cross section and are widely used as Conduit for transporting fluids, such as pipelines for transporting oil, natural gas, Coal Gas, water and certain solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight when its bending and torsion strength is the same, and it is an economic section steel. It is widely used to manufacture Structure parts and machinery parts, such as petroleum drill pipes, auto transmission shafts (consisting of shaft pipes, telescopic sleeves and universal joints), bicycle frames and steel scaffolds used in construction. circular parts made of steel pipes can improve the availability of materials, simplify the manufacturing process, save materials and working hours. steel pipes have been widely used for manufacturing.

In the world, carbon steel seamless gas pipes are mainly used to transport oil and gas . There are roughly three types of pipes: submerged arc welding pipes include straight submerged arc welding pipes and spiral submerged arc welding pipes. High frequency straight seam welded pipe and seamless steel pipe. The same is true in China, where LSAW, SSAW, ERW and SMLS are the main types of steel pipes. Of course, the main character of carbon steel seamless gas pipe is no welding seams and are formed by cold drawing or rolling round steel after piercing. No matter what aspect it is, it is higher than ordinary steel pipes, and seamless steel pipes will be treated seamlessly, so the ability to resist pressure will be very strong. Seamless steel pipes do not show many rust marks after being used for a period of time like common steel pipes, and seamless steel pipes do not cause various damages to human bodies when being used.

Carbon steel seamless steel tube is a kind of strip steel with hollow cross section and no seams around.  Steel pipes have hollow cross sections and are widely used as pipelines for transporting fluids, such as oil, natural gas, gas, water and some solid materials.  Compared with solid steel such as round steel, steel pipe has the same bending and torsion strength and lighter weight. It is an economical cross-section steel and is widely used in manufacturing structural parts and mechanical parts, such as petroleum drill pipes, automobile transmission shafts, bicycle racks and steel scaffolds used in construction.  Making annular parts with steel pipes can improve the material utilization rate, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sleeves, etc. Currently, steel pipes are widely used for manufacturing.  Steel tubes are also indispensable materials for all kinds of conventional weapons. Barrels and barrels of guns are made of steel tubes.  Steel pipes can be divided into round pipes and special-shaped pipes according to the shapes of cross-sectional areas.  Since the circular surface area is the largest under the condition of equal circumference, more fluid can be transported by the circular pipe.  In addition, the cross-section of the ring is relatively uniform under internal or external radial pressure, so most steel pipes are round pipes.  Making annular parts with steel pipes can improve the material utilization rate, simplify the manufacturing process, and save materials and processing time, such as rolling bearing rings, jack sleeves, etc. Currently, steel pipes are widely used for manufacturing.

Black Carbon Welded Steel Pipe

Circular parts made of steel pipes can improve the availability of materials, simplify the manufacturing process, save materials and working hours. Steel pipes have been widely used for manufacturing. Carbon steel seamless gas pipes are mainly used to transport oil and gas in the world. There are roughly three types of pipes: submerged arc welding pipes include straight submerged arc welding pipes and spiral submerged arc welding pipes. High frequency straight seam welded pipe and seamless steel pipe.  The same is true in China, where LSAW, SSAW, ERW and SMLS are the main types of steel pipes.  First of all, it is necessary to explain that the main technical requirements of oil and natural gas transmission steel pipes for pipeline technology are mainly strength, rigidity, impact toughness and weldability. Due to the difference of transmission medium-oil and natural gas and the difference of natural gas with rich gas and commonly used purified natural gas, as well as the difference of transmission sections (river crossing section, onshore transmission section (and areas of categories I, II, III and IV) and seabed transmission section), there are different technical requirements for steel pipes.

What Is the Difference between Galvanized Steel Pipe And Galvanized Seamless Steel Pipe?

Galvanized seamless pipes are generally hot dip galvanized and have a thick galvanized layer for greater corrosion resistance and longer service life. With the improvement of construction quality, the service life and strength requirements of the pipeline system are also increased. Galvanized seamless pipe is often used instead of galvanized steel pipe for fire fighting, air conditioning and other pipeline systems for circulating water and gas medium transmission with higher requirements.

Compared with galvanized seamless steel pipes, galvanized steel pipes are more simple.

Hot dip galvanization is the pickling of welded steel pipe first, in order to remove iron oxide on the surface of the steel pipe, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning,and then it is sent into the hot-dip galvanizing tank.

The hot-dip galvanized steel pipe matrix and the molten plating solution undergo complex physical and chemical reactions to form a corrosion-resistant and compact zinc-iron alloy layer, and the alloy layer is integrated with the pure zinc layer and the steel pipe matrix.Galvanized seamless steel pipe is more corrosion-resistant and expensive than galvanized steel pipe.

Tianjin Credit Import and Export Trading Co., Ltd. manufactures galvanized pipes, seamless pipes, SSAW steel pipes, LSAW steel pipes, and various metal products.

Comparison of Spiral Steel Pipe and Straight Seam Steel Pipe

The production process of straight seam steel pipe is relatively simple. The main production processes include high-frequency welding straight seam steel pipe and submerged arc welding straight seam steel pipe. The straight seam steel pipe has high production efficiency, low cost and rapid development.The strength of spiral welded pipe is generally higher than that of straight seam welded pipe. The main production process is submerged arc welding.Compared with the straight seam steel pipe of the same length, the weld length of spiral steel pipe increases by 30-100%, and the production speed is low.

In terms of welding process, the welding method of spiral steel pipe is the same as that of straight seam steel pipe, but there are inevitably many T-joints in the straight seam steel pipe, so the probability of welding defects is greatly increased, and the welding residual stress at the T-joint is large, and the weld metal is often in the three-dimensional stress state, which increases the possibility of cracks.Moreover, according to the regulations of submerged arc welding process, each weld should have an arc striking and arc extinguishing position, but each straight seam steel pipe can not meet this condition when welding the circular seam, so there may be more welding defects at the arc extinguishing position.
