Engineering FAQ
Follow the piping line class and stress analysis. SCH 80 provides greater wall thickness for higher design pressure on the same NPS.
Yes for standard LR 90° elbows—the center-to-end A is governed by NPS in B16.9, while wall thickness and weight differ by schedule.
Heat treatment follows the material grade and project spec. Normalizing or stress relief can be applied when required on the PO.
SR elbows are available on inquiry with reduced A dimensions per B16.9 SR tables.
