Description

20 #(Grade 20) seamless steel pipe

product introduction
20 # seamless steel pipe is widely used in petrochemical and other industries for its excellent performance and suitable price. 20 #. There are national standards such as seamless steel tubes for fluid transportation (GB / t8163-2008), seamless steel tubes for low and medium pressure boilers (gb3087-2008), seamless steel tubes for petroleum cracking (gb9948-2013) and seamless steel tubes for high pressure fertilizer equipment (gb6479-2013).

There are great differences in price and effect of 20 # seamless steel pipes of different standards. At present, the price of 20 # seamless steel pipes manufactured according to GB 6479-2013 is about 1000 yuan / ton higher than that manufactured according to GB / T 8163-2008.

standards for 20 # seamless steel pipes
(1) GB / t8163-2008 seamless steel pipe for fluid transportation
(2) gb3087-2008 seamless steel tubes for low and medium pressure boilers
(3) seamless steel tubes for petroleum cracking (GB / T 9948-2013)
(4) seamless pipe for high pressure fertilizer equipment (GB / T 6479-2013)
(5) GB / T 5310-2017 seamless steel tubes for high pressure boilers (in the standard, the steel number is 20g; G refers to boiler steel tubes)

The content of main elements (such as C, Si, Mn) in the chemical composition of 20 × seamless steel pipe in each material standard is the same. The content of residual elements (such as Ni, CI, Cu, Mo, V) in steel in gb9948-2013 and GB 6479-2013 are the same, but there are slight differences between GB / T 8163-2008 and the above two standards. The main difference of chemical composition lies in the content of P and s.
