Nickel Alloys: ASTM/ASME SB 336 UNS 2200 (Nickel 200), UNS 2201 (Nickel 201), UNS 4400 (Monel 400), UNS 8020 (Alloy 20/20 CB 3), UNS 8825 (Incoloy 825), UNS 6600 (Inconel 600), UNS 6601 (Inconel 601), UNS 6625 (Inconel 625), UNS 10276 (Hastelloy C276)
Production Process
The production of steel elbows according to GOST 17375-2001 (with bending angles up to 180 degrees) involves heating using gas or induction heating (high-frequency current). This heating process helps compensate for the high stresses arising during the forming of the parts.
Preheated blanks are stretched over a specially shaped mandrel using a press. After forming, while the product remains hot, it is calibrated to achieve the required geometric dimensions. Final mechanical processing includes trimming and beveling the edges.
Optional Features:
Elbows with a 90-degree angle that meet GOST 17375-2001 standards can be manufactured with galvanized coatings.
Polyurethane coatings can be applied upon request to ensure the protection of the products during long-term storage or transportation.
