Din 17175 16Mo3 Seamless High Pressure Alloy Steel Boiler Tube

Short Description:

16Mo3 Pipe belongs to EN10028 specification. It is a pressure vessel grade steel that could be used under high temperature and pressure. There are different standards and schedules of these chromium molybdenum alloy pipes. The NFA 36–205 16Mo3 Seamless Pipe has a thickness ranging from 4m to 350mm depending on the diameter of the pipe and the pressure classes. There are other classes that are applied for very high temperatures such as the 16Mo3 1.5415 Boiler Pipe which is used primarily in boilers. There are pipes that could be used with high precision in high sensitivity applications such as the 1.5415 16Mo3 Steel Seamless Pipe. Since these seamless pipes have less absolute roughness, they are easy to install with minimal use of tools and can create better sealing at connections.

Product Introduction

The DIN 17175 16mo3 Round Pipe is a type of chromium molybdenum alloy that has the wall thickness of 2.6mm. The different numbers in the grading indicate the different mechanical properties such as the wall thickness, diameter and pressure containments. The UNS K11820 16Mo3 Sch40 Pipe for example belongs to schedule 40 which is denoted by the Sch40 and it is used mostly in condensers and refrigerators. DIN 17175 16Mo3 Welded Pipe is stronger and withstand higher temperatures up to 600 degrees Celsius. The EN 10253-2 Grade 16Mo3 Alloy Steel Seamless Pipe has carbon content in 0.12-0.2 % of the entire composition. It also has manganese in 0.4-0.9% proportions in the composition. There are different product versions under EN 10216-2 Grade 16Mo3 Alloy Steel Pipes and each of them has specific mechanical properties. The 16Mo3 Chrome Moly Steel Pipe types are used in elevated temperatures. They are used typically in industrial boilers, oil and gas industries and particularly in pressurized steel vessels that undergo high temperatures as well.
