Container tube Fire fighting pipeFire fighting pipeline refers to the pipeline material used for fire fighting, connecting fire fighting equipment and equipment, transporting fire fighting water, gas or other media. Due to special needs, the thickness and material of the fire pipe have special requirements, and spray red paint to transport fire water.- API N80 Oil casingOil country tubular goods (OCTG) are mainly used for the drilling of oil and gas wells as well as the transportation of oil and gas. Oil casings are primarily used to support the wellbore during drilling and after well completion, so as to ensure the smooth progress of the drilling process and the normal operation of the entire oil well after completion. Oil casings are the lifeline for maintaining the operation of oil wells. Due to different geological conditions, the stress state downhole is complex, with tensile, compressive, bending, and torsional stresses acting on the pipe body comprehensively, which places high requirements on the quality of the casings themselves.
API 5CT Oil PipeOur oil pipeline steel is specially designed for oil and gas transportation, featuring high strength, corrosion resistance, and excellent weldability, making it suitable for harsh working environments and complex operating conditions in the petroleum industry. The product complies with international standards such as API 5L, covering various grades (e.g., X42 to X80), ensuring safe and reliable energy transportation. Custom sizes and coating options are available to meet your project requirements.
Pickling Carbon Steel PipeCarbon steel pipe is made of ingot or solid round steel through perforation to make a tube, and then hot rolled, cold rolled or cold drawn to make. Carbon steel pipes are divided into hot rolled and cold rolled (drawn) steel pipes. Carbon steel pipe is a common metal pipe, composed of carbon and iron and other elements. It has good corrosion resistance, bearing capacity and machinability.- Q255/SM400 Welded steel pipeWelded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip after crimping, welded steel pipe wall is thicker, has higher strength and stiffness, can withstand greater pressure and impact, its excellent mechanical properties, welded steel pipe is a widely used in construction, petroleum, chemical, light industry, machinery and other fields of pipe.
- Q345/S355JR/Gr.50 Seamless Steel PipeSeamless Pipe is a durable material made from carbon steel, a steel alloy with iron and carbon. Because of its strength and ability to withstand stress, carbon steel pipe is used in a variety of heavy-duty industries like infrastructure, ships, distillers, and chemical fertilizer equipment.
ISO 2531 Ductile Iron Double Welding PipeDuctile iron pipe refers to the use of more than 18 casting hot metal after the addition of spheroidizing agent, through the centrifugal ductile iron machine high-speed centrifugal casting into the pipe, referred to as the ductile iron pipe, ductile iron pipe and ductile casting pipe. Mainly used for the transmission of tap water, is the ideal choice of water pipeline materials.- K7 100mm 150mm Ductile Cast Iron PipeDuctile iron pipe refers to the use of more than 18 casting hot metal after the addition of spheroidizing agent, through the centrifugal ductile iron machine high-speed centrifugal casting into the pipe, referred to as the ductile iron pipe, ductile iron pipe and ductile casting pipe. Mainly used for the transmission of tap water, is the ideal choice of water pipeline materials.
- En545 En598 C25/C30/C40 Ductile iron pipeDuctile iron pipe refers to the use of more than 18 casting hot metal after the addition of spheroidizing agent, through the centrifugal ductile iron machine high-speed centrifugal casting into the pipe, referred to as the ductile iron pipe, ductile iron pipe and ductile casting pipe. Mainly used for the transmission of tap water, is the ideal choice of water pipeline materials.
Q215/A573 Welded steel pipe used for welding steel pipe is steel plate or strip steel, which is divided into furnace welded pipe, electric welding (resistance welding) pipe and automatic arc welding pipe because of its different welding process. Because of its different welding forms are divided into straight seam welded pipe and spiral welded pipe two kinds. Because of the shape of its end, it is divided into circular welded pipes and special-shaped (square, flat, etc.) welded pipes.
Our carbon steel welded pipes are manufactured from high-quality materials complying with international standards including ASTM A53, API 5L, and ASTM A135. These pipes feature excellent weld integrity and dimensional consistency, making them ideal for low-pressure fluid transportation, structural applications, and fencing systems. Custom lengths and surface treatments are available upon request to meet specific project requirements.
Our carbon steel welded pipes are manufactured using advanced ERW (Electric Resistance Welding) or LSAW (Longitudinal Submerged Arc Welding) technology. The production process incorporates precision forming systems with automatic seam tracking, in-line heat treatment for stress relief, automated ultrasonic testing for weld integrity, and computer-controlled cutting to length. These integrated measures ensure strict wall thickness tolerance of ±10% and consistent product quality.
In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
