4130 pipe

Seamless Pipe is tubing made to the pipe schedule. Alloy pipe in the power industry generally refers to A335 material, but in the oil and gas market, 4130 pipe is used. This product is made to the pipe schedule but uses A519-4130 as the controlling seamless specification. The material is then heat treated to L80, P110 or the customer’s specified properties. This material is easily welded and is generally used for above ground applications and utilizes the fittings, flanges and other piping components with the same 4130 chemistry. This product is a good alternative to replace X65 through X80 piping items where the usage or repair is too small for mill production.
