Introduction to spiral-welded steel pipes
What is spiral welded steel pipe?
Spiral welded steel pipe (SSAW), also known as spiral submerged arc welded steel pipe, with the English name “Spiral Submerged Arc Welding Pipes,” is a type of steel pipe with spiral patterns running along the pipe wall. It is manufactured using arc-welding technology.
Spiral-welded pipes are currently being produced in various sizes (DN200–DN4000). Suitable for use in large to extremely large-scale systems. This type of pipe is currently one of the indispensable products in many fields, specifically: construction, pipelines, shipbuilding,…
Why choose spiral welded pipes?
- The welds are evenly distributed into the tube in a spiral style, so every position on the tube has a relatively uniform force-bearing capacity.
- Designed with standard thickness, outstanding hardness, and good impact resistance,
- It is applicable in many fluid environments, such as liquids, heat, compressed air, etc.
- High durability and a long service life can last up to several decades.
- Easy to handle and preserve in many ways, namely surface painting or galvanizing,…

Standards for manufacturing spiral-welded pipes
There are many standards applied to spiral-welded steel pipe products. According to research compiled by Bao Tin Steel, on the market today, the most popular spiral welded pipe production standards are:
API 5L standard
The API (American Petroleum Institute) standard is a standard issued by the American Petroleum Institute, specializing in industries related to the oil and gas sector.
Welded steel pipe products in general and spiral welded pipes in particular are manufactured according to API 5L standards with many outstanding features. Specifically: withstand great pressure, withstand high temperatures, and work in many environmental conditions (gasoline, oil, chemicals, etc.).
ASTM standards
ASTM standards are a set of technical standards for materials and products around the world issued by the ASTM Organization (American Society for Testing and Materials).
On the market today, there are two ASTM standards commonly applied to SSAW steel pipe production: ASTM A53 and ASTM A252.
BS standards
BS standards (British Standards) are standards for building and evaluating the quality of products or services in many fields. Specifically: civil, construction, industrial, electronics, health,… This is a standard issued by the British Royal National Standards Agency.
You may not know that in the field of manufacturing welded steel pipes, BS standards are regulated by the symbol BS 4360. Two commonly used steel grades in this standard are Grade 43 and Grade 50.
Application of spiral welded steel pipes
SSAW steel pipes are commonly used in many fields, specifically:
- In the pipeline system, transporting clean water, wastewater, etc.
- Used in construction projects. For example fences, factory frames, warehouses, scaffolding,…
- Compressed air piping system, hot steam,…
- In the fire protection system
- Hydroelectric and thermal power systems
- Used in mechanical factories, machine frames, vehicle frames,…
- Application in shipbuilding
- Used as electric poles, traffic light poles, advertising boards, etc.
