Seamless Tubing
Seamless tubing is fabricated without a welded seam. A cylindrical bar of steel called a billet is pierced through the center and drawn over a mandrel. The billet is then forced through a die, rolled and stretched until it meets the exact diameter and wall thickness as required by ASME (American Society of Mechanical Engineers) dimensional specification.
James Duva, Inc. provides seamless tubing with the strength and durability to withstand high working pressures and temperatures. It is available in a wide variety of alloys, outside diameters, wall thickness and finishes.
Strength Under Stress
Seamless tubing is known for retaining its integrity under stress. Most tubing failures occur at the welded seam. Because seamless tubing has no weld seam, it can withstand much higher working pressures than welded tubing – 20% higher ASME working pressures than welded tubes of the same material and size. Seamless tubing is equally strong around its entire circumference.
Certain applications will specify the need for seamless tubing, and will discourage the use of welded tube because the engineer cannot risk the possibility of a defect in the weld. Although there are many applications of noncritical nature that successfully utilize welded tubing, Seamless tubing is the preferred option in critical applications.
