Seamless steel pipes are widely used in many industries. Among them, Ø42 seamless steel pipe
is one of the most commonly used products thanks to its outstanding advantages, which we will learn about in the following article.
Seamless steel pipe Ø42
“seamless steel pipe Ø42 is a type of seamless pipe with an outer diameter of 42mm (DN32). Available in different thicknesses and lengths depending on customer requirements”.
In particular, seamless steel pipes Ø42 have properties such as high durability, good impact resistance, and high corrosion resistance. Because of these properties, seamless pipes Ø42) have become one of the optimal materials for industrial applications.
Detailed information about seamless steel pipe Ø42 products:
- Standard steel grades: ASTM, ASTM A106, ASTM A53, ASTM API 5L, A179…
- Diameter: Phi 42, DN32
- Thickness: 1.65mm – 9.7mm, available in sizes SCH5, SCH10, SCH20, SCH40, SCH60, SCH80, SCH120…
- Origin: Japan, Korea, China, Taiwan…
- Length: 6m -12m (however can be cut according to customer requirements).

Introducing seamless steel pipe Ø42
1. Standard ASTM A53
ASTM A53 is one of the standards for the production of seamless steel pipe with diameters from 1/8 inch to 26 inches. Standards and regulations related to ASTM A53 include:
You may not know that the ASTM A53 standard has three common types:
- Type F — Class A continuous, butt welds.
- Type E — Resistance welding, Grades A and B.
- Type S — Seamless (seamless steel pipe), Class A and B.

2. Standard ASTM A106
Similar to ASTM A53, however, ASTM A106 is a set of standards that prescribes specifications for seamless steel pipes used in applications involving high temperatures and pressures.
ASTM A106 applies to seamless steel pipes in general and high-temperature seamless carbon steel pipes in particular in sizes NPS 1/8 to NPS 48 [DN 6 to DN1200], inclusive of the average wall thickness. as given in ASME B36.10M.
Besides regulations on size, ASTM A106 also regulates types and levels as follows:
- ASTM A106 Grade A
- ASTM A106 Grade B
- ASTM A106 Grade C
3. Tiêu chuẩn API 5L
The API 5L standard provides requirements for the production of two product grades (PSL 1 and PSL 2) of seamless and welded steel pipe for use in pipeline transportation systems in the petroleum and natural gas industries course.
- API 5L PSL1 steel grades include: A, B, x42, x46, x52, x56, x60, x65, x70,…
- API 5L PSL2 includes steel grades B, x42, x46, X52, x56, x60, x65, xx70, x80,…

Compared with other types of steel pipes, seamless steel pipes (DN32) have many outstanding advantages, meeting the needs of users. To know what advantages this Ø42 seamless steel pipe has, please read on.
Advantages of seamless steel pipes Ø42
- High-pressure resistance: Judging from the production process, seamless steel pipes have no welds on the pipe surface. Therefore, its pressure resistance will be much better than that of other types of pipes.
- High durability: The abrasion, corrosion, and oxidation resistance of seamless steel pipes Ø42 is very good, helping to increase the durability and longevity of the product.
- Weldless production offers better durability and resistance to mechanical stress.
- High uniformity: A seamless steel pipe is a type of steel that is punched from round steel billets by rolling, pulling, and extruding to create the desired dimensions, so the uniformity over the entire length is higher than that of welded pipes.
- Various sizes and thicknesses
- Good impact resistance
- Flexible applications in many fields,…
If there are advantages, there will certainly be disadvantages. Next, we invite you to join Bao Tin in learning about the disadvantages of cast steel pipes.

Disadvantages of seamless steel pipes Ø42
- Higher price compared to welded steel pipes: Because the production process of seamless pipes (Ø42) is more complicated than that of welded steel pipes, the price of this product will be higher (if considering the same size and grade).
- Longer delivery time: seamless steel pipes are 100% exported products from abroad, so delivery time may be longer.
