Fabricated Low Carbon Steel Weld Ring for Oil & Gas Pipeline Systems

Low Carbon Steel Weld Ring
Low Carbon Steel Weld Ring

At Imperial Weld Ring, we understand well that oil and gas pipeline system components need to function in harsh and corrosive environments. We kept this knowledge in mind when we fabricated low carbon steel weld rings for oil and gas pipeline systems at the request of a customer. Used in high and low temperature applications, these rings were components of internal sleeves and applied on custom tapered pipe fittings for internally coated pipeline systems. We manufactured the rings to precise tolerances of ±0.005" in custom sizes with an epoxy coating for corrosion resistance and metal studs that ensured proper spacing for the weld joint. We used a series of processes and our open back inclined presses to fabricate the low carbon steel rings (ASTM A109 Temper 4 and ASME SA-36). The rings were slit and cold drawn, sheared, beveled and chamfered, stamped, rolled with custom ring rollers, ground, and resistance spot and stud welded. Secondarily, the rings were degreased, cut with a band saw, deburred, dot peen marked, and then coated with an aluminum oxide weldable primer. Although ring diameters varied, widths of 1.000" and thicknesses of 0.125" were typical. Cold drawn finished, the rings were split into sections upon request, fitted with custom spacers, and custom packaged. The low carbon steel was ASTM/ASME certified, identified with 100 percent heat/lot traceability, and inspected with customer supplied gages. We worked from customer specifications and CAD drawings and made 10,000 weld rings for domestic and international delivery to locations specified by our customer.

We established a synergy with this OEM and continue to meet the demands of its global applications. To find out how we can do the same for you, contact Imperial Weld Ring directly.
