Choosing seamless steel pipe according to safety regulations

We choose different steel pipes for our engineering project as we will use their special characters for serving us. So does for the pick of seamless steel pipe. Today, we would talk about the method for choosing it over safety regulations. From the picture we can see that, for petroleum and gas industries, we would concern the pressure question firstly. Thus, for different hydrogen sulfide concentration, we get the different volume for the seamless steel pipe. Of course, this means that the pressure taking is also different. More details, we can get it from the following picture.
