MS Seamless Pipe PINAMAEXIM
Our MS seamless pipes are manufactured from high-quality, low-carbon billet, extruded and hot-rolled without any welds to produce a strong, precision-engineered tube. With sizes ranging from 1/2 to 24 OD and wall thickness up to 20mm, they meet IS 1239, ASTM A53, and API standards . Featuring uniform wall thickness, excellent pressure tolerance (+20% vs welded), and superior strength, they are corrosion-resistant and suitable for coatings. These pipes are ideal for critical applications oil & gas, boilers, and structural scaffolding. Durable, smooth, and dimensionally accurate, MS seamless pipes deliver long-lasting performance in demanding industrial environments.

Circular steel pipe is both openings and have hollow concentric sections of steel larger than the surrounding. The specifications of steel pipes are indicated by appearance dimensions and inner diameter and wall thickness, with a wide range of dimensions from very small diameter capillary to large round steel pipe of several meters in diameter. Round steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry, and special uses. It can be divided into seamless, ERW, LSAW, SSAW steel pipe according to the production process.

Seamless steel pipe is a steel pipe that is perforated from a whole round steel and has no welds on the surface. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and pipe jacking. According to the cross-sectional shape, the seamless steel pipe is divided into two types: round and special-shaped. The maximum diameter is 900mm and the minimum diameter is 4mm.
According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes.

Our company can supply many materials of seamless pipes, mainly 20#, 45#, astm a106, astm a53, api 5l. We can also produce other materials of steel pipes according to the customers' requirements.
