The quality standards for seamless steel pipe

Seamless ( CARBON SMLS) Steel Pipe is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. The seamless pipe is then finished to dimensional and wall thickness specifications in sizes from 1/8 inch to 34 inch OD.

 

Sunny Steel can secure and process your Seamless Pipe order, including specialized requirements and cut to length up to 50 feet in length and wallthickness max with 50mm or even greater .

 

Below is the standard what we can produce for the pipes :

ASTM A 53 specification for black steel seamless pipes

ASTM A 106 Gr. B seamless carbon steel pipes for high-temperature service

ASTM A 161 seamless low-carbon and carbon molybdenum steel still tubes for refinery service

ASTM A179 specification for seamless cold-drawn low-carbon steel heat-exchanger and condenser tubes

ASTM A192 specification for seamless carbon steel boiler tubes for high-pressure service

ASTM A 210 specification for seamless medium-carbon steel boiler and superheater pipes

ASTM A 213 specification for seamless ferrite alloy steel boiler, superheater and heat-exchanger pipes

ASTM A 519 seamless carbon and alloy steel for mechanical tubing

ASTN A 556 seamless cold-drawn carbon steel feedwater heater tubes
