With so many different products like seamless pipes, welded pipes and flanges it might be overwhelming trying to pick which seamless steel pipe to use for your business applications, or even what they can be used for in the first place. There are many different properties of each pipe that give it a unique use in its respective industries, and if you’re going to master the different types of piping materials and what they’re used for, it’s important that you learn the different types, what they can be used for and how they can be applied to various industries.
To give you a hand, we’ve put together a simple article that details most of the regular uses for ERW steel pipe, why it’s used and how it could be applied to a generic industrial company.
Types of Stainless Steel Pipe
Filler Metal Selection Critical in Controlling Carbon Levels
Selecting filler metal for pipe fittings is about enhancing the properties of the weld and meeting the requirements of the application. Filler metals with an “L” designation, such as ER308L, provide a lower maximum carbon content, which can help retain corrosion resistance in low carbon stainless alloys. As an example: if you weld a 304L base metal with a standard 308 filler metal, you’ll actually raise the carbon content of that joint and increase the chance of corrosion. In high purity applications – food, beverage, pharmaceutical – that low carbon content is critical for maintaining corrosion resistance. Conversely, a filler metal with an “H” designation provides higher carbon content for applications requiring greater strength, particularly at high temperatures. Filler metals with higher silicon levels, such as ER309LSi, increase weld puddle fluidity, improve tie-ins and increase travel speeds for greater productivity. The 309 series filler metals are also particularly adept at joining dissimilar stainless steels and in overlay applications.
