Stainless Steel 321H Pipe and DIN 1.4878 ERW Tube/ S32109 Seamless Pipe

What Is Stainless Steel 321H Pipe?

Stainless steel 321H Pipe is an austenitic compound that is stabilized utilizing titanium or niobium. The grade is a higher carbon modification of the 321 grade of stainless steel. The pipes in this range can withstand higher temperatures ranging up to 1500 degrees F due to their elevated carbon levels. These pipes also offer better tolerances against creep-rupture while resisting intergranular corrosion. The pipes can be readily welded similar to the 321-grade, making use of standard welding procedures.

DIN 1.4878 ERW Tube Vs SS S32109 Seamless Pipe

ERW and seamless components are amongst the important processes used in manufacturing piping equipment. Both these modules can be differentiated based on some basic features.

The manufacturing process- Din 1.4878 ERW Tube is rolled and then welded longitudinally in place. A SS S32109 Seamless Pipe is an extruded metal that is produced by passing steel billets.
Working pressures- Seamless pipes have 20% extra working pressure in comparison to an erw tube.
Strength- Seamless products are generally stronger in comparison to Erw components.
Sizes- ERW tubes are available in an array of sizes, while seamless pipes are available in sizes up to 36 NM.

SS 321H Tube Features

Some of the important features of 321H tubes

Superior oxidation resistance in temperatures up to 816 degrees C.
Excellent performance in low temperatures.
Resistant to various forms of corrosive media.
Welded with ease making use of standard welding procedures.
Enhanced tolerance to intergranular corrosion after welding.
Ductile and possess enhanced formability.

ASTM A312 TP 321H Material Application

Astm A312 Tp 321H has many features that make it highly versatile and used in a range of industries and critical applications. This include

Chemical and petrochemical processing
Pharmaceutical production
Aircraft exhaust stacks and manifolds
Jet engine parts
Welding equipment
Waste treatment
Furnaces, burner pipes
High-temperature mineral processing
Equipment for food processing systems
Expansion joints

What Is Grade 321H Boiler Tubes?

Grade 321H boiler tubes are modules that are located on the interior of boilers to heat water and produce steam. There are two types of boilers namely water and fire tube boilers. Manufactured using seamless tubes, the boilers in this grade are able to tolerate rising temperatures and pressures due to their superior composition and tolerances.

SS 321H Pipe Heat Treatment

Grade 321 pipe cannot be treated and hardened by heat treatment. The only procedure to harden these components is through the cold-rolling prices. Pipes within the grade are annealed at high temperatures and quickly quenched with water. This process allows the pipe to possess superior hardness and excellent corrosion resistance properties.

Difference Between SS 321H Welded Pipe And AISI 321H Seamless Tubing

Industrial applications have evolved with time and so have the manufacturing procedures. However, seamless and welded piping equipment is still predominant in the industry. Both these procedures have properties that set them apart from each other. The major difference between these components is the manufacturing process. The AISI 321H Seamless Tubing is pierced by hot billets, and the extruded metal is shaped. In the SS 321H Welded Pipe the metal is rolled and then welded in place. Seamless tubes can be produced in square, rectangular and circular shapes, while welded pipes are always round in shape. Apart from this seamless, tubing can work with higher pressures compared to its welded counterpart.
