Heat treatment is a critical manufacturing stage for austenitic and duplex seamless stainless steel pipe. It can influence microstructure, corrosion behavior, mechanical properties, dimensional condit...

The corrosion resistance of stainless steel depends not only on its grade and chemical composition but also on the condition of its surface. Heat tint, oxide scale, embedded carbon-steel particles, sh...

Schedule 10S, 40S and 80S identify standardized nominal wall thicknesses for stainless steel pipe. For the same NPS, the outside diameter normally remains constant while the wall thickness and inside ...

Seamless stainless steel pipe used in LNG and cryogenic systems must be selected using the minimum design metal temperature, design pressure, fluid composition, governing code, material toughness, pro...

Seamless Pipe for Sour Service: What Buyers Should Specify Before OrderingSeamless pipe for sour service cannot be specified by adding “for H2S service” to a standard pipe inquiry. Suitability depen...

Seamless stainless steel pipe is frequently evaluated for hydrogen production, storage, compression, transfer and distribution systems. However, specifying stainless steel or seamless construction doe...

Seamless line pipe is used in oil and gas projects where the specified diameter, wall thickness, pressure, temperature, fluid composition or project requirements make seamless manufacture an appropria...

Selecting seamless stainless steel pipe for chemical service requires more than choosing between 304L, 316L and duplex stainless steel. Corrosion performance depends on the complete process environmen...

Seamless pipe dimensions are rarely manufactured to one exact value. Outside diameter, wall thickness, length, ovality and straightness are controlled within permitted tolerance ranges defined by the ...

A pipe schedule is not a universal pressure rating. The pressure capability of seamless steel pipe must be evaluated using the governing design code, design pressure, design temperature, material allo...

Seamless steel pipe sizes are commonly described by Nominal Pipe Size, outside diameter and schedule. These terms are related, but they do not mean the same thing. Misunderstanding them can result in ...

A seamless steel pipe price cannot be evaluated accurately by comparing the quoted price per ton or per meter alone. Material grade, outside diameter, wall thickness, manufacturing route, heat treatme...
