Hoa Phat galvanized steel pipe standards

As mentioned in the previous article, quality standards are a measure to evaluate the chemical composition and mechanical properties of steel pipes. These parameters help reflect the size, misuse, system compatibility, safety level, and lifespan of steel pipes. In today’s article, we will learn about Hoa Phat galvanized steel pipe standards. This will also be the answer to the question: Why is Hoa Phat steel pipe always chosen?

Standard ASTM A53

Hoa Phat galvanized steel pipes are produced according to many standards. One of them is ASTM A53 Grade A and Grade B standards. Hoa Phat steel pipes are certified for quality according to ASTM A53 standards by reputable organizations such as SGS, TUV, BV, etc. This standard applies to galvanized pipes with sizes DN15–DN300 (1/2–12 inches). Thickness: 2.27–12.7 mm.

Hoa Phat galvanized steel pipes that comply with this standard usually have good durability. Along with that is the ability to withstand high pressure and to be less susceptible to corrosion. Therefore, they are often used for pipeline systems carrying water, gas, steam, gas, oil, etc. Even used in load-bearing structures, boilers, etc..

It can be seen that, even though it is the same brand, each standard produces a type of galvanized steel pipe with different specifications and weights. Therefore, when buying a suitable tube, customers always need to carefully look for the type of tube they are about to buy. Understand the parameters and standards to choose the best quality products.

Standard ASTM A500, TCVN 3787-83

The next standards applied by Hoa Phat to galvanized steel pipes are two standards: ASTM A500 and TCVN 3787-83. At Hoa Phat, these two standards are applied to pipes with sizes 12.7–126.8. Thickness ranges from 0.7 to 6.0 mm. Typically, both of these standards stipulate characteristics such as:

Tiêu chuẩn ASTM A500

Ống thép mạ kẽm có thể đáp ứng tiêu chuẩn ASTM A500 này khi chúng được sản xuất theo quy trình mạ kẽm nhúng nóng phù hợp. Lớp mạ phải tuân thủ các yêu cầu về độ dày. độ bám dính và khả năng chống ăn mòn. Đây cũng là yếu tố giúp ống tôn mạ kẽm tiêu chuẩn ASTM A500 đặt được những đặc điểm sau:

  • The pipe has a minimum tensile strength of 50,000 psi (345 MPa) and a minimum toughness of 20% elongation in 2 inches (50 mm).
  • Minimum tensile strength 50,000 psi (345 MPa) and minimum toughness 20% elongation in 2 inches (50 mm).
  • The pipe has good weldability to conventional welding methods.

TCVN 3783:2012 – Welded steel pipes – Common techniques

This standard specifies general technical requirements for welded steel pipes, including galvanized steel pipes. Vietnam standards for galvanized steel pipes include the following main contents:

  • Dimensions, shapes, and tolerances of steel pipes
  • Quality steel and galvanized coating
  • Mechanical properties of steel pipes
  • Test Method
  • Marking and labeling requirements

With the regulations in this TCVN galvanized steel pipe, Hoa Phat steel pipe always achieves high quality. Not only is it heat resistant, has good load capacity, and has a long lifespan, but it also has a beautiful design. The fact that this brand has become a national steel brand has proven how highly users evaluate the quality of products here.

However, the two standards mentioned above still have slight differences. That is, ASTM A500 has lower requirements for zinc coating than TCVN 3787-83. ASTM A500 has a wider size range than TCVN 3787–83. Choosing the standard type of galvanized steel will depend on your requirements.

Standard BS EN 10255:2004 (BS 1387:1985)

This standard is the standard that stipulates the technical requirements for galvanized steel pipes. Steel pipes produced according to this standard are used for many purposes. For example water pipes, gas pipes, and fire protection systems,…
Hoa Phat pipes according to BS EN 10255:2004 standards have pipe sizes from DN15 – DN100 (1/2′ – 4′ inch). Thickness from 2.6 – 4.5 mm. Galvanized steel meeting this standard must have a maximum carbon content of 0.25%. Steel pipes when marketed must have a minimum tensile strength of 355 MPa. Minimum ductility 20%. The zinc coating must have a minimum thickness of 85 g/m² for both the inside and outside of the steel pipe.
