Carbon Steel Flanges Manufacturer in India

Carbon Steel Flanges

Leading Supplier and Exporter of Low CS Blind/ WNRF Flange

As one of the leading Carbon Steel Flanges manufacturers in India, we produce superior quality flanges using good quality raw materials with routine quality checks considered by our quality team. Although the material used in the manufacture of Low CS Plate Flange is relatively soft and weak, it compensates by demonstrating properties such as outstanding ductility and toughness. Because of its low carbon to iron ratio in the alloy of CS Blind Flange, the alloying costs of this product tends to be lower, thereby making it an ideal material for less demanding applications. Typcially, Low carbon steels are considered in applications for making car body panels because they tend to be malleable.

We are Manufacturing Killed Carbon Steel Forged Flange as per ASME B16.5 Standards, Check Price list of Normalized Carbon Steel Weld Neck Flanges

Carbon Steel Weld Neck are well suited for use in hostile environments, especially those applications where the temperature and pressure could be extreme or it could encounter other sources of stress. Since carbon steel pipe flanges are pliable by nature, which could improve its effectiveness for certain applications, all the same, lowering its effectiveness for other uses. We quote reasonable prices for good quality pipes. Click here to learn more about the Carbon Steel Flange Price list.

Low Carbon Steel Slip On Flanges are produced with the inside diameter being slightly bigger than the pipe's outside diameter and are provided with a raised or flat face.
