How do You Choose Steel Pipes？
When choosing to purchase SSM pipes, you need to provide us with as much of the following as possible so that we can better serve you:
1. Purpose: You must clarify the steel pipe’s intended use, whether it is conveying liquids, gases, structural support, machining, etc.
2. Material: The material and grade of the steel pipe should be according to the purpose and the reference standard, such as carbon steel, stainless steel, or nickel alloy.
3. Size: According to specific needs, determine the required outer diameter, inner diameter, wall thickness, and length.
4. Pressure and temperature: Consider the operating environment’s pressure and temperature requirements and choose steel pipes that can withstand these conditions.
5. Corrosion resistance: Whether steel pipes in corrosive environments require special treatment.
6. Standards and certifications: Ensure the selected steel pipes meet relevant industry standards and certifications, such as ASTM, API, etc.
7. Cost: While ensuring that the technical requirements are met, if you pay more attention to cost, you can also tell us your target price in advance.
How Are Pipes Made?
The steel pipes we offer are divided into two types based on the manufacturing method: seamless and welded.
Seamless steel pipes are typically made by hot rolling or cold drawing, also known as cold rolling.
Welded steel pipes are mainly made using electric resistance welding (ERW), submerged arc welding (SAW), and high-frequency resistance welding (HFW).
For a detailed understanding of the steel pipe manufacturing process, please refer to the article “Overview of Steel Pipe Manufacturing Process.”
Seamless Pipes vs Welded Pipes
When deciding between seamless and welded steel pipes, the following comparison will guide you to the right choice.
| Items | Seamless Pipes | Welded Pipes |
| Manufacturing Process | Seamless steel pipes are manufactured through hot rolling, cold rolling, or cold drawing from a solid round steel billet without weld seams. This type of pipe tends to be more expensive due to the complex production process. | Welded steel pipes are produced by rolling steel plates or strips into pipe shapes and then welding them. The production process is relatively simple, resulting in lower costs. |
| Dimensional Accuracy | Seamless pipe is suitable for small diameter, high-pressure, and high-strength applications. The size range typically includes an outer diameter of 6mm to 610mm and a wall thickness of 0.5mm to 75mm. | Welded pipes are suitable for large diameter, low pressure, and cost-effective applications. The size range is extensive, with an outer diameter of up to 3000mm and a wall thickness ranging from 2mm to 50mm. |
| Material Selection | Seamless steel pipes are typically made from high-quality carbon steel or alloy steel. | Welded steel pipes can be made from various materials such as carbon steel, stainless steel, or other types, providing a wide range of material choices. |
| Weld Seam Inspection | Seamless steel pipe: no welded seams, so no need for weld seam inspection. | Welded steel pipes require critical weld seam inspection (e.g., X-ray and ultrasonic) to ensure quality. |

Installation and Maintenance of Steel Pipes
Although pipe installation and maintenance are follow-up tasks after procurement, understanding this knowledge will assist you, suppliers, and engineering personnel in carrying out procurement work.
Installation:
1. Preparation: Check the appearance and size of the steel pipe to ensure it meets the requirements. Prepare the necessary tools and materials for installation.
2. Cutting and welding: Cut the steel pipe as needed and weld or connect it securely to ensure a firm and leak-free joint.
3. Support and fixation: Install brackets and fixings to prevent the steel pipe from moving or vibrating during operation.
4. Testing and debugging: Conduct pressure testing and leak detection after installation to ensure the system operates normally.
Maintenance:
1. Regular inspection: Periodically check the appearance and joints of the steel pipe and promptly address any issues.
2. Cleaning and anti-corrosion: Regularly clean the steel pipes, especially those transporting corrosive media, and apply anti-corrosion treatment when necessary.
3. Replacement and repair: Replace or repair damaged or severely worn steel pipes promptly to ensure the system’s safety and reliability.
4. Record and Management:
– Establish maintenance records.
– Track the use and maintenance history of steel pipes.
– Formulate reasonable maintenance plans.
Pipes vs Tubes
Many users may still be uncertain about whether to choose pipes or tubes. Below is a brief comparison; perhaps it will help to clarify.
| Items | Pipes | Tubes |
| Dimensions | The size of a pipe is typically indicated by its nominal pipe size (NPS) and its pipe wall thickness, also known as its schedule (SCH). The nominal size may not be the same as the actual outside diameter. For instance, the outside diameter of a NPS 2 steel pipe is 2.375 inches, while the inside diameter depends on the pipe wall thickness. | Tubes are typically described by their outer diameter (OD) and wall thickness. The precise measurements of the outer diameter and wall thickness are crucial and are commonly expressed in metric (mm) or imperial (inch) units. For instance, a stainless steel pipe could have an outer diameter of 20 mm and a wall thickness of 2 mm. |
| Shape and precision | Pipes are generally cylindrical and have looser tolerances and lower surface finish requirements. | Tubes come in various cross-sectional shapes and require high dimensional accuracy as well as a high surface finish. |
| Manufacturing Process | The production processes for pipes include welding, seamless manufacturing, and extrusion. These processes focus on ensuring that the pipes have the necessary pressure-bearing capacity and durability. Welded pipes are created by rolling steel plates into tubes and welding the seams. On the other hand, seamless pipes are produced by heating and extruding steel billets to ensure high strength and no welds. | The production process for tubes includes cold drawing, hot rolling, welding, and more. The focus is on achieving high surface quality, precise dimensions, and strong mechanical properties. Cold drawing improves surface finish and dimensional accuracy, while hot rolling is suitable for producing large-size, high-strength tubes. |
| Material choice | The choice of pipe materials is primarily based on fluid transportation requirements, focusing on pressure and corrosion resistance. | Tube material selection is based on mechanical properties and application requirements, focusing on precision, strength, and corrosion resistance. |
