JIS seamless pipe is steel pipe that has been created by JIS

and meets certain performance requirements. Manufacturers

follow Japan Industrial Standards voluntarily.

Japanese Industrial Standards (JIS) developed by the

organization apply to a wide variety of industrial services

and technologies such as automobiles, metallurgy, ships and

medical equipment.

The method for making cold-drawn seamless pipes involves

taking a round ‘billet’ or bar of steel and boring it in

the center, turning it, cutting it, heating it to make it

more pliable, then ‘drawing’ it (extruding or pulling it)

to make it a longer and thinner tube.

JIS seamless pipe according to alloy, stainless steel or

carbon. It tests steel’s properties, hardness, resistance

to corrosion, pitting, heat treating processes and others.

The results are listed in a main JIS steel grade for steel

pipe as below.

Measurement size & Testing

JIS seamless pipe testing covers many specifications,

including alloy, size, toughness and composition. Those

using steel products purchase the product that fulfills the

requirements they need for what they are building.

We have the professional engineers, measurement the size of

steel pipes.

And then calculate a steel pipe and tube theoretic weight.


Packed in wooden crates, wrapped in plastic, and suitably

protected for sea-worthly delivery or as requested.

Both ends of each crate will indicate the order no., heat

no., dimensions, weight and bundles or as requested.


Pipes are supplied in hexagonal bundles or round bundles

tied with steel strip.

Weight of bundle – up to 5000 kg upon request of customer.

Each bundle is furnished with three tags.
