welding dye penetrant

Particle Inspection and Dye Penetrant Inspection). Position, prepare and check the welding equipment. Receive, handle and maintain consumables; Prepare, check and protect materials and work area ready for welding. Complete and check the finished weld ready …

The assemblies are capable of 1.1″ axial movement, 0.5″ lateral movement, and are designed for 35 psig at an operating temperature of 1200°F. One end is beveled for welding and the other end is fitted with a special 316 stainless steel clamp assembly. The expansion joints were dye-penetrant tested and hydro-tested prior to shipment.

The unit was post-weld heat treatment and 100% radiographic examined the circumferential and long seams after the post-weld heat treatment, plus pneumatically tested at 61 psi, the bellows were leak tested to 15 psig between the plies, and dye-penetrant tested prior to shipment.

It is designed for an operating temperature of 338°F at 4.5 psig and 2 3/8″ of lateral deflection. The expansion joint was 100% dye penetrant tested, the bellows longitudinal seams were 100% X-rayed, PMI examined, and hydro-tested prior to shipment. Read More

The unit is 118″ CL-to-CL of the elbow, 132 3/8″ face-to-face, and 24″ OD. They are designed for an operating pressure of 310 psig at 400°F with 1 1/8″ of lateral deflection. The unit was hydro-tested at 465 psi, X-ray tested the bellows long seam and pipe, PMI all alloys, and 100% dye-penetrant exam on all weld prior to shipment. Read ...
