Product Overview
Carbon Steel Pipe takes carbon as the primary alloy element with carbon content ranging from 0.12% to 2.0%. We supply two mainstream categories: seamless carbon steel pipe and ERW welded carbon steel pipe, manufactured with Q235, 20#, A106 Gr.B, A53 Gr.B mainstream grades under GB/T8163, ASTM A53, ASTM A106, API 5L standards. Balanced strength, easy machining and competitive cost make it widely adopted in construction, petrochemical, metallurgy, power, machinery and marine engineering sectors for fluid transportation and load-bearing frameworks.
Carbon steel pipe features the following aspects:
1. High strength: Carbon steel pipe has high strength and hardness, can withstand large external forces.
2. Weak corrosion resistance: Carbon steel pipe corrosion resistance is weak, vulnerable to acid, alkali and other chemical substances.
3. Low cost: Carbon steel pipe production costs are relatively low, the price is relatively affordable.
4. Good processability: Carbon steel pipe is easy to process and welding, can be manufactured out of a variety of shapes and specifications of the pipe.

Two Main Product Types
- Seamless Carbon Steel Pipe: Hot rolled / cold drawn forming, no welding seam, high pressure resistance, for boiler, oil pipeline, hydraulic high-pressure circuit.
- ERW Welded Carbon Steel Pipe: High-frequency longitudinal welding, uniform wall thickness, low cost, for municipal water supply, fire protection, building structure.
Scope of application
Carbon steel pipe is a common pipe, a very wide range of applications, mainly involving the following aspects:
1. Construction: Carbon steel pipe can be used in construction projects to transport water, gas, oil and other media, such as water supply and drainage pipes, HVAC systems, natural gas pipelines, etc.
2. Petrochemical: Carbon steel pipe can be used in the field of petroleum, chemical and other media such as oil and gas, chemicals, such as oil pipelines, chemical pipelines, etc.
3. Mechanical manufacturing: Carbon steel pipe can be used for mechanical manufacturing in the transport of hydraulic oil, lubricating oil and other media, such as hydraulic systems, mechanical equipment, etc.
4. Other areas: Carbon steel pipe can also be used in aerospace, automotive manufacturing, marine engineering, metallurgy and other fields.
Common problems
Carbon steel pipe in the use of the process may appear in the following common problems:
1. Corrosion problems: Carbon steel pipe in a humid environment is susceptible to corrosion, resulting in damage to the pipe.
2. Fatigue problems: Carbon steel pipe in the long-term use of the process is susceptible to fatigue, resulting in the rupture of the pipe.
3. Welding problems: Carbon steel pipe welding quality has a great impact on the service life of the pipe, the poor quality of welding can easily lead to pipe leakage or rupture.
4. Cleaning problems: Carbon steel pipe in the use of the process requires regular cleaning, otherwise it is easy to accumulate dirt and impurities, affecting the effectiveness of the use of the pipe.

FAQ
01.What's the difference between seamless and welded carbon steel pipe?
Seamless pipe is integrally pierced forming without weld line, higher pressure resistance for boiler & oil medium; welded pipe is low-cost for low-pressure water/gas municipal pipelines.
02.How to choose material grade for boiler pipelines?
03.What payment terms can you accept?
04.Can you provide third-party inspection before shipment?
Yes, we support SGS, BV and other authorized third-party institutions to conduct factory inspection and sampling test as customer demand.
