Shandong Seamless Steel Tube Factory teaches you four ways to identify 16Mn seamless steel pipe material
1. Check the texture certificate.
2. On-site sampling tests.
3. The factory will always brush the outer surface of the pipe.
4. The visual difference with the appearance of ordinary carbon steel is minimal, and the color of 16Mn is dark.
16Mn pipe material test standards: C (carbon) 0.12--0.18 Si (silicon)? 0.55 Mn? Manganese? 1.00--1.6, the chemical reagent test is more accurate, the spectrometer must use good equipment Caixing, if you have a long time Gas cutting experience, see cutting sparks, can also be discerned. There are simple ways to change the law, use the board to identify the strength of the way. Experienced people can also discern sounds. The most accurate way to test elements, and high-precision spectroscopic instruments. 16Mn steel corrosion at room temperature than 20 # 45 # steel corrosion resistance.
The 16mn seamless steel pipe knowledge source is provided by Shandong Seamless Steel Tube Factory.
In fact, most of the Hydrocarbon Refrigerant refrigerant is one of them. The main hydrocarbon refrigerant is energy-saving and environmental protection are the two major advantages: energy saving; hydrocarbon refrigerant air conditioning than using R134 R22 air conditioning energy saving 15% to about 35%. Environmental protection: hydrocarbon refrigerant belongs to natural refrigerant, so no pollution of the atmosphere of ozone no damage and the greenhouse effect is almost zero.
