Material of Carbon Steel Seamless Pipe,and Method of use.The meaning of Fluid

Conveyance Tube.

16 mn seamless tube of two standards

16 mn is high strength low alloy structural steel carbon content is 0.1% - 0.25%, main alloy

elements manganese, silicon, vanadium, niobium and titanium

16 mn seamless tube of the main production standards: GB/T8163-2008 (conveying fluid),

GB6479-2000 (seamless steel tube used in high pressure chemical fertilizer equipment).

Liaocheng city development zone will rev steel pipe co., LTD.,API 5CT Casing Pipe perennial

production and sales of major steel pipe manufacturer, alloy pipe, seamless steel pipe, 20 45 #

seamless steel pipe, seamless tube, 16 mn geological pipe.

16 mn seamless steel pipe: one of the 16 mn for seamless steel tube material. Seamless steel

tube of a term in the past. As of now, Q345B seamless steel tube, and the relevant material for

Q345C Q345D, Q345E, quality grade respectively, A B C D E said does not require impact test

impact test temperature is 20 degrees + 0-20 to 40 degrees.

The main purpose of the 16 mn seamless steel pipe:

Special grade of steel used for Bridges as 16 MNQ, auto special steel girders for 16 MNL, special

steel pressure vessel for the 16 MNR.

This kind of steel is rely on adjust the amount of carbon (C) to improve the mechanical properties

of steel, therefore, according to the carbon content of high and low, this kind of steel can be

divided into:

Low carbon steel, carbon content less than 0.25% generally, such as 10, 20 steel, etc.;

Medium carbon steel, carbon content is in commonly between 0.25 ~ 0.60%, 35, 45 steel, etc.;

High carbon steel, carbon content is generally greater than 0.60%. This kind of steel is generally

not used in the manufacture of steel pipe

One of the 16 mn seamless pipe for seamless steel tube material. Is a term for the seamless steel

tube. As of now, Q345B seamless steel tube, and the relevant material for Q345C Q345D,

Q345E, quality grade respectively, A B C D E said does not require impact test impact test

temperature is 20 degrees + 0-20 to 40 degrees.

Quality of ABCD said quality grade Q235 grade is divided into A, B, C, D four levels, from low to

high quality by A to D.

Different quality level requirements are as follows: A, S, P, C, Mn, Si chemical composition and fu,

fy, delta (delta) 10 5, 1800, according to the buyer needs to provide cold bending test, but not

specified impact energy, HanTanLiang and manganese content is not as delivery conditions.

B - provide S, P, C, Mn, Si chemical composition and fu, fy, delta (delta) 10 5, 180 'cold bending

test.

Also provide + 200 C when the impact energy Ak 27 j C - or higher except as class B

requirements, also provide 00 C impact energy Ak acuity 27 j. D - except as class B requirements,

also provide - 200 - c when the impact energy Ak acuity 27 j E, except as class B requirements,

also provide - 400 - c when the impact energy Ak acuity 27 j.

Stainless steel pipe and carbon steel seamless steel tube of a few differences

The difference between the stainless steel pipe and carbon steel seamless steel tube, carbon

steel elbow is mainly refers to stainless steel pipe and carbon steel seamless steel tube of the

differences in design rules, that is to say, the two kinds of steel design rules, not universal. This

difference is summarized as follows:

The stainless steel pipe design rule cannot be applied to carbon steel seamless steel tube isstainless steel and carbon steel seamless steel tube with three fundamental difference between:

A, when the cold work hardening stainless steel tube, for example, the anisotropic when it is bent,

i.e., horizontal and vertical properties are different.

Can take advantage of the increased by cold working strength, but if compared with the total area

of bending area is lesser and ignored this increases, the strength increased to some extent, can

improve the safety factor.

Second, the stress/strain curve shape is different, the elastic limit of the stainless steel tube is

about 50% of the yield stress, as defined in standard of the minimum, the yield stress value is

lower than the yield stress value of the medium carbon steel.

Three, stainless steel tube has no yield point, usually expressed in o0.2 the yield stress is

considered to be equivalent value.
