Introduction Stainless Steel Pipe Weight Chart

The stainless steel pipe weight chart is an essential buying tool for fabrication, contractors, engineers, manufacturers, and industrial buyers. Whether you’re buying stainless steel pipe for construction, food grade usage, chemical industries, pharmaceutical applications, or industrial fabrication, weight matters significantly when you need to get estimates for material and transport costs, structural load needs.

Stainless steel pipe can be of many different grades, sizes, and schedules. India uses most SS 304 and SS 316 grades and Schedules such as Schedule 10, 40 and 80.

Since stainless steel pipes are sold predominantly by weight, the buyers may want a standard stainless steel pipe weight chart to be able to ascertain total pipe amount needed for their specific application.

In this guide we discuss: stainless steel pipe weight calculation, pipe size charts and schedules, pipe weight tables and applications.

What Is a Stainless Steel Pipe?

A stainless steel pipe can be characterised as a seamless hollow cylinder of stainless steel alloy, which, in fact, is an alloy formed of chromium and additional elements.
 
Having a wide range of features, stainless steel pipes have found a wide range of usages in various industries such as:
 
  • Good resistance against corrosion
  • High strength
  •  Longer durability/service life
  • Weldability
  • Beautiful appearance
  • Less maintenance

Some common applications of stainless steel pipes:

  • Industrial pipelines
  • Water treatment plants
  • Food processing industries
  • Pharmaceutical industries
  • Oil & gas industries
  • Chemical industries
  • Construction work

Why Is Pipe Weight Important?

Knowledge of pipe weight allows the buyer to:

Estimate Material Cost- 

Buyers purchase the majority of stainless steel pipes based on a per-kilogram rate.

Calculate Freight charges-

The cost of freight is determined by the weight of the pipe.

Design of a structural system-

The weight of the pipe is important for designing the supporting members.

Inventory control-

Precise calculation of pipe weight leads to an efficient ordering and stock-keeping system.

Fabrication planning-

Fabricators do Cutting, welding, lifting and erection activities of the pipe by its weight.

  • Very good
  • chemical resistance
  • Good life service
  • Better corrosion protection

Stainless Steel Pipe Weight Formula

The standard calculation method of stainless steel pipe weight is:

Weight(Kg/m)

=OD Thickness Thickness0.02491

Where:

  • OD=Outside Diameter(mm)
  • Thickness=Wall Thickness(mm)

This formula calculates the estimated weight of pipe per meter.

Example Calculation

Weight = 60.3 3) 3 (0.02491) Weight = 4.28 kg/m.
Therefore, the weight of a 60.3mm OD and 3 mm wall thickness Stainless Steel pipe is 4.2 8 kg/m.

Therefore, the weight of a stainless steel pipe 60.3 mm OD with 3 mm wall thickness is 4.28 kg/m.

Understanding Pipe Schedule

The wall thickness of the pipe is known as the schedule.

The following are the popular schedules.

ScheduleApplication
SCH 10 Low-pressure piping, light usage
SCH 20Medium-duty piping
SCH 40General industrial use
SCH 80

High-pressure applications

As the schedule increases, the pipe weight also increases.

The weights of SS 304 & SS 316 pipes:

 One of the most often asked questions is whether an SS 316 pipe would weigh more than an SS 304 pipe.

Answer:

Marginally

GradeDensity
SS 3047.93 g/cm³
SS 3167.98 g/cm³

This difference will normally be insignificant for commercial calculations.

The choice should always be dictated by:

  • Corrosion resistance
  • Chemical service
  • Service conditions
  • Cost

not weight.

Weight of seamless pipe compared with weight of welded pipe.

It is thought that the weight of seamless pipe is more than that of welded pipe.

Actually:

For equal values of,

  • OD
  • Thickness
  • Length

The weight will be more or less the same.

The differentiation depends on the fabrication process and pressure rating.

Factors Affecting Stainless Steel Pipe Weight

Outer diameter
The more diameter of the pipe is, the more weight it holds.

Wall thickness
Wall thickness correlates with weight.

Pipe length
As expected, the longer the pipe, the more length of pipe will bear more weight.

Pipe Schedule
With an increase in schedule the wall thickness increases and therefore the weight increases.

Grade of Stainless Steel
The density between SS 304 and SS 316 is not significant, thus the difference in weight is very minor.,
