Information

2" × 1" BSP Class 3000 A105 Steel Reducing Coupling belongs to the group of threaded high-pressure fittings. Reducing couplings are available in all inch sizes. Each fitting is marked with its size, material grade, heat number and pressure class. They ensure installation safety and durability. All threaded fittings are supplied with 3.1 certificates.

Marking: couplings are marked with the size, pressure class, material grade, heat number and, in some cases, thread type. Markings are made in accordance with applicable standards.

Steel grades: fittings are available in carbon and stainless steel grades, including A105 – LF2 – 304 – 316 – A106 – API 5L – A182 – A312 – A333 – A335 – A350 – A420 – A403 – A694 – F304 – F304L – F316L – F321 – TP304 – TP304L – TP316 – TP316L – TP321 – LF2 CL. 1 – 1.4404 – 1.4401 – 1.4301 – S355J2 – P355NL1 – P355NH – P355QH – L360NB – 1.0566 – 1.0562 – A420-WPL6 – A333-Gr.6 – StE 355.

Advantages: easy selection of thread and steel grade.
Disadvantages: not available in metric sizes.

Certificates with impact tests are available.
