Manufacturing

Yaolong Tube uses only raw material from approved steel suppliers for all of our ornamental ASTM A554 tubing, with specific Rockwell and surface finish requirements. Tube production is completed entirely inline, beginning with high quality roll form tooling that minimizes marking, laser welding, ID and OD weld bead conditioning, final sizing, cut to length, deburring, specified polishing, surface finish protection and packaging for shipment. This inline process keeps work-in-process problems to a minimum and reduces material handling.

Quality Control For ASTM A554 Round Tubes

Our tube mill operators complete all required ASTM A554 and customer specifications testing, based on fabrication and surface finish requirements. Mechanical tests are performed at regular intervals, and all tubing is 100% inline eddy current tested. If the tubing is to be mandrel bent, ID tolerances are critical. Therefore, plug gauges are utilized to ensure adequate clearance and customer-required dimensions are met. Mechanical polishing compounds and equipment are continually monitored using polished tube samples
