Product Description
ASTM A182 F51 equates to UNS S31803. This was the original caption for a 22% Cr duplex stainless steel. However, as explained in an earlier article, manufacturers optimised the composition towards the top end of the limits to improve pitting corrosion resistance. This grade, with a tighter specification, is captioned as F60, equating to UNS S32205. Consequently, S32205 can be dual-certified as S31803, but not vice-versa. It accounts for around 80% of overall duplex stainless steel production. Langley Alloys stocks Alloy 2205+, which is Alleima’s proprietary product that provides enhanced machinability as standard’. Our stock range goes from ½” up to 450mm diameter solid bars, plus hollow bars and plates too.
Butt welding tee is a kind of pipe connection accessory used for vertical or oblique connection between the supervisor and the branch pipe. Its main feature is that the nominal diameter of the supervisor and the branch pipe is the same, and the connection method is butt welding (the two ends are connected to the pipe by welding).Structural symmetry: The diameter of the supervisor and the branch pipe is the same, the overall structure is symmetrical, and the resistance of the fluid is small when circulating in the pipe, which is suitable for the scene of uniform distribution of medium flow. Firm connection: butt-welded connection, after welding, the interface has high strength, good sealing, and can withstand high pressure and temperature, which is suitable for medium and high-pressure pipeline systems. Various materials: According to the use environment (such as medium corrosiveness, temperature pressure, etc.), carbon steel, stainless steel (such as 304, 316), alloy steel pipe and other materials can be selected. It is widely used in industrial pipeline systems such as petroleum, chemical industry, natural gas, electricity, water supply and drainage, etc. It is used to change the direction of fluids or divert and confluence, such as branch connections of pipelines in oil pipelines and steam pipelines.
