The Best Carbon Steel Pipes Manufacturer You Can Trust

We provide outstanding premium quality carbon steel pipes with the best value-added service from start to finish – The world material & service of choice!

Carbon steel pipe is used in a variety of industries like oil & gas, infrastructure, water & wastewater, distillers, chemical fertilizer equipment, drainage construction, offshore projects, structural foundations, and among others.  

Our steel pipe manufacturing facilities are located in China Merchants Development Zone (CMDZ) in the Zhangzhou City of Fujian Province, holding a land area of 53 hectares where our skilled employees are engaged to provide the highest quality steel pipes & excellent service.

Our manufacturing & SSAW welding techniques are surely recognized due to their strength, wall thickness, pressure-resistant, and anti-corrosion delivering greater customer satisfaction.

SSAW steel pipe welding process allows the steel pipes manufacturers to produce large-diameter pipes that are suitable for construction piling, bridge pipings, tunnel projects, roads, elevated highways, building structures, retaining walls, trestle, port, seawalls, cofferdams, and harbor structures.


Pipe pile is a type of steel pipe used for construction and foundation piling. Our spiral welded SSAW steel pipes are commonly used for bridge foundations, structures, retaining walls, offshore foundations, trestle, port, seawalls, cofferdams, and harbor structures.


Helical Pipes have used in various industries: chemical, mechanical, agricultural, and among others. New development in measurement and computational fluid dynamics (CFD) techniques were used to clearly figure out the flow phenomena and fluid flow patterns in the helical pipe. 


Pipe bridge is commonly used to construct bridges that allow a pipeline to run over rivers, highway overpasses, or any unstable land areas. 


Carbon Steel Pipe Characteristics

Carbon steel pipe has high mechanical performance, high weldability, durable, flame resistant, high corrosion resistant, high adaptability to different applications that make them suitable for under ocean water application, water lines, to transport oil & gas, drainage, construction piling, tunnel projects, roads, and highways. 

Our manufacturing & welding techniques are surely recognized due to their strength, wall thickness, and pressure-resistant delivering greater customer satisfaction. 

  • Durable lining quality
  • Long-term cost-effective
  • Abrasion resistance materials against collision
  • High-performance treatment
  • Safe to use
  • High durability
  • Slow the rate of diffusion of water and oxygen from the environment
  • Deformation resistant

Carbon Steel Pipe Uses & Applications

Oil & Gas

helicoidal steel pipe

Carbon steel pipes are used to transport oil and gas over long distances. 

Spiral welded pipe has been used for gas transmission pipes in Europe and North America for decades, but recent projects in the USA and China have clearly demonstrated the competitiveness of this type of pipe. 

Water Pipeline

It is also used for the transfer and distribution of water.

Lining — Water Service

  • Cement mortar
  • per AWWA C200

Aside from clean water, carbon steel pipes are often used for wastewater, hydropower, and industrial other applications.

Bridge Pipe


Pipe bridge is designed and built specifically to support a walkway for maintenance purposes or to construct bridges that allow a pipeline crossing a river, highway overpass, or any unstable land areas.

Piling Pipe

Piling Pipe is normally used for deep foundations farther down from the surface that you will find at the building sites, offshore projects, oil, and gas facilities.

Having the right structural support for deep foundations comes with many options, but SSAW steel pipe piles are the most customizable when it comes to diameter, length, and thickness.

Drainage & Sewer

Carbon pipes are also common for highway drainage and sewer.

The carbon steel pipe isn’t only economical upfront, but they are also economical compared to other pipe materials.

The large-diameter steel piping is most often used in pressure pipes for sewage and wastewater applications.

Transporting Steam

helical pipes

Carbon steel pipes can also be used to transport steam in some manufacturing and agriculture facilities.

Steam boilers are normally constructed of carbon steel pipes converting steam into motion.
