About This Category

What Seamless Steel Pipe Is Actually For

Seamless pipe is formed from a solid billet rather than a rolled and welded strip, which removes the weld seam as a point of weakness under pressure and cyclic load.

That is why pressure, high temperature and low temperature specifications almost always call for seamless production.

Seamless Steel Pipe detail
Hot and cold finished seamless pipe for pressure, temperature and critical service.
Problems It Solves

What Goes Wrong When This Is Specified Loosely

Seamless Steel Pipe Questions

Why does seamless cost more?
It is made by piercing and rolling a solid billet, a longer route than forming and welding strip. You pay for the absence of a weld seam.
Can you supply low temperature grades?
Yes, including grades intended for low temperature pressure vessel and heat exchanger service.
Is impact testing included?
It is performed when the order specifies it. State the test temperature and standard with the enquiry.
