The Secret About Astm Sa213 Alloy Tube That You Do Not Know

In your opinion, what is the ASTM sa213 alloy tube? Just is something that thick and round? Or various tubes that can be seen everywhere? Or other very broad concept? But actually, they covered more than you know.

At this point, you may be curious alloy steel pipe in the end what the mysterious point. In fact, they are unique specifications in many ways.

Firstly, Steel Pipe Size allowable deviation is very strict. OD 6 ~ 10mm allowable deviation ± 0.20mm; greater than 10 ~ 30mm allowable deviation ± 0.40mm; greater than 30 ~~ 50mm, allowable deviation ± 0.45mm; greater than 50mm, the allowable deviation of ± 1.0%. Cold rolled precision seamless steel tubes. The length of the tubes: diameter ≤ 30mm 2 ~~ 6m; outside diameter> 30 ~ 70mm 3 ~~ 10m; outside diameter> 70mm of 4 ~~ 10m. The same batch of material length does not deviate by more than ± 1%.

Next, this product is high appearance quality on requirements. Alloy steel pipe, the outer surface shall not exist crack, folded, layered, rolling off and scarring defects.

Finally, it must also comply with the strict rules of acceptance. It is the quality of the supply-side monitoring department to search seized and acceptance; Steel pipe to the plant should be accompanied by proof of the batch of material to meet the standard requirements and ordering contract quality certificate.

So, when be asked something about ASTM sa213 alloy tubes, do not just talk about some surface abstraction, you can also tell people its high quality requirements and demanding requirements of factory.
