Global Seamless
Global Seamless manufactures hot-finished and cold-drawn carbon steel seamless tubes, with an installed capacity of 24,000 metric tons per year.
Its tubes serve industries including mining, oil and gas transport, automotive, cranes, hydraulics, boilers, power generation, cooling towers, railways, nuclear power, and chemicals. The company focuses on meeting international standards and quality expectations, produces pipes to customer-specific requirements, and inspects products at every stage through final dispatch.
SEAMLESS STEEL PIPE (SMLS PIPE)
Seamless pipe is made by piercing a solid billet to form a hollow shell, with no weld or seam. It bends and flares well.
It offers higher pressure capacity and strength than welded ERW pipe, so it is widely used in high-pressure, thermal, and boiler equipment. Weld seams in welded pipe can be a weak point that affects overall performance.

TUBING & CASING
Casing is a large-diameter pipe inserted into a newly drilled borehole to protect and support the wellstream, much as a spine's bones protect the spinal cord.
