    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.
