API refers to the American Petroleum Institute that has laid down the standards and grades for manufacturing flanges. This API Flange is a ring type flange that has a raised face. API 6A Flange manufacturer In India produces these flanges within a size range of ½ inch to 24 inches. API 6A Blind Flange has dimensions based on outer diameter, thickness, and nominal size and is measured in inches. API 605 Slip On Flanges is used to block off a section of the pipe. They are used in industries such as oil, natural gas, petroleum pipeline, and gas explosives.
API 6A Weld Neck Flange is a solid disk with mounting holes. The only difference between general and blind 30 Inch API Flange is that the bling flange does not have a hole to allow the liquid to pass by. 24 Inch API 650 Flange has a working temperature range of -75 degrees F to 250 degrees F. The minimum wall thickness of API 3000# Flange is 200 inches and is used in areas where high working pressure is needed. The main function of this API 6a Type 6b Raised Face Flanges is to join the pipes thereby increasing the support strength. The main characteristic of these flanges is their toughness and hardness.
API Spec 6A Plate Flange can be surface treated in various applications. This is done to increase the life span of API 6A 6B And 6bx Flanges and also to improve the ability to resist corrosion. 5000# API Socket Weld Flange is made up of A105 carbon steel and has a minimum yield strength of 45000. API 10000 Flange is manufactured from high steel alloy after heat treatment and has a minimum yield of 75000. We as manufacturers of API Threaded Flange try to create high quality products and supply them at affordable prices.
