Stainless Steel Tube

A stainless steel tube is a hollow structure manufactured in seamless and welded types. SS Tubing is produced in various grades of 300 & 400 series with a superior chemical composition which can be installed in different conditions.

SS Seamless Tubing due to their intricate manufacturing process, need prolonged production periods. They have varied size restrictions. Typically the size range starts from 16″ to 24″ nominal. The smallest size of a tube beginning at 1/8″. Conversely, Stainless Steel welded tube face no such limitations, stretching from 30″ to 36″ due to the presence of welded seams.

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.

A Stainless steel round tube is stronger and offers better performance than SS Pipe. 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.

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.

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.

In precision-demanding applications, tubes are favored, focusing on their outer diameter (OD). Industries like medicine and chemical processing depend on accurate tube, giving less attention to the inner diameter (ID).

Pressure rating chart guides the user regarding the stainless steel tube’s resilience under intense pressure. Anticipation of pressure variations is a critical determinant of a tube’s length. Spiral tube, employed in HVAC systems, provide cost-effective installation and minimal maintenance.

Tube may feature single (austenitic, ferritic, or martensitic) or dual-phase (duplex or super duplex) microstructures, with dual-phase alloys renowned for superior strength and corrosion resistance.

A tube technically mirrors the shape of a cylinder. So it is an elongated metal cylinder. Yet, during production its length will be dictated by standards like ASTM. The primary function of tube has always been transportation. They ferry across different liquids, gases, steam, and other substances.

DIN 17457 vs EN 10216 – 5 Stainless Steel Tube

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 tube can be custom designed in different shapes and sizes as per requirements.

Standards like DIN 17457 regulate austenitic stainless steel welded tube, subjecting them to treatments like pickling and annealing. Industries like chemical treatment plants and pressure vessels are frequent users of these tubes.

Difference between Stainless Steel Seamless, Welded and Spiral Tube

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 tube 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 tube. The ERW tube 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 tube.

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 tubing are that they are aesthetically appealing and are easy to install and maintain. These tubes are very versatile and have lower pressure drops.

Advantages

SS Seamless Tube offer advantages in strength and pressure-bearing capacity, simplifying pressure calculations with their seamless construction. Yet, welded tubing enable lengthier constructions and cost less to manufacture.

Before installation, leak tests check for excess leakage, while pressure tests ensure pipeline functionality. Structures fashioned with tubular formations characterized by substantial wall thicknesses are inclined to manifest heightened resilience in comparison to their piped counterparts. Their propensity to exhibit high strength makes them ideal for structural applications.
