What is the minimum & maximum size that can be produced in a stainless steel tube? What are the different shapes of SS tubing?
Manufacturers usually keep the minimum outside diameter (OD) of a stainless steel seamless tube at around 1.5 mm. The maximum OD of the tube must be kept to 1524 mm. Manufacturers keep the minimum wall thickness of the tube at typically around 0.1 mm while the maximum WT can be up to 5 mm.
Round tubes are the most common and widely used shape for the thin wall stainless steel tube. The square thick wall stainless steel tube has a square cross section with four equal sides at right angles to each other. These tubing can also be produced in custom shapes to meet specific design requirements.

Advantages of stainless steel seamless tube and welded tubing?
Seamless products provide higher strength and integrity compared to stainless steel welded tube. These seamless products have a smooth, uninterrupted interior surface, reducing the likelihood of corrosion or contamination.
Welded material is generally more cost-effective than seamless stainless steel erw tube. This tubing can be easily customized and fabricated to meet specific design requirements or project application needs.

What are stainless steel tubes?
A stainless steel tube is a hollow structure manufactured in seamless and welded types. Stainless steel tube is produced in various grades of 300 & 400 series with a superior chemical composition which can be installed in different conditions.
DIN 17457 stainless steel tube is German standard which covers both seamless and welded. The EN 10216 – 5 Stainless Steel Tube can be both hot and cold rolled and later galvanized. These tubes can be readily welded following standard welding procedures. The versatile tubes can be custom designed in different shapes and sizes as per requirements.
What are Stainless steel seamless, erw and welded tubes? Check size, price and process wise differences
A stainless steel seamless tube is manufactured by piercing hot steel billets through metal and precisely shaping it. These tubes have a long production process with a long procurement time.
The cost of a seamless stainless steel tube is thereby higher due to the difficulties faced in manufacturing it. Their quality however compensates for the high price. Stainless steel tube manufacturers find it difficult to produce seamless tubes above 24 inches.
A Stainless steel erw tube is produced as metal is cold rolled and coiled in a cylindrical shape. A current is passed through the longitudinal seam to melt and weld it. The tubes don’t require any filler material and are cheaper than seamless tubes. The erw tubes can be availed in different sizes.
A Stainless steel welded tube is manufactured as steel strips, plates, or coils rolled in a circular shape using special machines.
The tube can be welded with or without filler material in custom sizes and shapes. They cost less than seamless tubes, but the use of filler material will determine their price compared to erw tubes.
What is the difference between leak test and pressure test of Stainless Tubing?
A leak test is used to test the pressure boundary of a Large diameter thin wall stainless steel tubing. The pressure test is performed to check whether the device can hold the pressure and maintain it for long periods. Pressure tests are performed 1.1 to 1.5 times the design pressure of the tube.
Is Stainless steel round tube stronger than a pipe?
A Stainless steel round tube is stronger and offers better performance than pipes. These tubes are utilized in applications that require good strength and durability. This is why the Heavy wall stainless steel tubing is used where there is a requirement of the precise outside diameter.
What is the difference between OD and ID? Is stainless tubing measured by ID or OD?
The outside diameter (OD) and the inside diameter (ID) can be differentiated based on the thickness of a wall. Thick wall stainless steel tube is used in structural applications and is measured by its outside diameter or ID or as ID and wall thickness.
What pressure is stainless steel tubing rated for?
The pressure rating of tubing is based on its thickness, outside diameter, and stainless steel grade. A thin wall stainless steel tube is designed to handle lower pressures and has a considerably lower pressure rating. A robust Large diameter stainless steel tube can handle pressures above 35000 psi.
What is Stainless steel spiral tube and its uses & advantages?
A Stainless steel spiral tube is a material that is constructed using a coil of prime metal into a spiral lock seam. The tubes are commonly seen in HVAC, ventilation, and spiral pipes.
The major advantages of these pipes are that they are aesthetically appealing and are easy to install and maintain. These tubes are very versatile and have lower pressure drops.
