Seamless pipes are made from a solid billet and contain no weld seams, offering superior strength, uniformity, and corrosion resistance. Welded pipes are produced by rolling and welding steel plates or strips and may have weaknesses at the weld seam, especially in high-pressure or corrosive environments.
Seamless pipes are used across a wide range of industries, including:
Oil & Gas
Petrochemical and Chemical Processing
Power Generation and Nuclear
Marine and Offshore
Pharmaceutical and Food Processing
Aerospace and Defense
Heat Exchangers and Boiler Systems
Fujian Guangxin PipeTech Co., Ltd.'s seamless pipes stand out with distinct advantages. We adopt internationally advanced hot-rolling, cold-rolling and other processes, and rely on more than 50 sets of equipment in five major workshops to achieve automated and precise production, ensuring high precision and stable quality of pipes. We strictly adhere to ISO 9001 and PED standards, conducting full-process inspection and traceability, which is superior to the industry's sampling inspection method. With an annual production capacity of over 8,000 tons, we can provide quick delivery. Moreover, we offer full-cycle services from product selection to after-sales support, far exceeding the single sales model of our peers.
Our butt - welded fittings comply with ASME/ANSI B16.9 and JIS B2311.
We offer flanges made from stainless steel, duplex stainless steel, and nickel alloy materials. These high - quality materials endow our flanges with excellent corrosion resistance, high - temperature stability, and mechanical strength, making them suitable for a wide range of applications in industries such as petrochemicals, power generation, and marine engineering.

Material selection depends on your operating conditions, such as pressure, temperature, and corrosion exposure.
For general corrosion resistance, 304/316 stainless steels are common.
For chloride environments, consider duplex steels like 2205 or 2507.
For high-temperature or aggressive chemicals, nickel alloys such as Inconel or Hastelloy are ideal.
Our technical team is available to help you choose the best option for your needs.
Our seamless pipes comply with major international standards including:
ASTM A312, A213, A269, A789, A790
ASME B36.10M / B36.19M
EN 10216, EN 10297, EN 10204 (3.1 / 3.2)
GB/T13296, GB/T14976
We also support third-party inspections (e.g., SGS, BV, TUV) upon request.
