ASME B36.10M Welded and Seamless Wrought Steel Pipe 

Material

ASME B36.10M defines dimensional standardization for welded and seamless wrought steel pipe used in piping and pipeline systems under high or low temperatures and pressures. The standard focuses on outside diameter (OD), wall thickness (Schedules), and mass/weight, while the steel grade (chemistry & strength) is selected separately based on service conditions and project codes.

Typical compatible materials include carbon steel and low-alloy steels produced as Seamless (SMLS), ERW, LSAW/SAW, depending on the required performance, inspection level, and cost targets.

Specifications

• Size Range (NPS): commonly supplied from NPS 1/8 up to NPS 60 (Schedule-based OD/W.T. system).

• Wall Thickness System: Schedule numbers plus legacy designations STD / XS / XXS.

• Manufacturing Types: Seamless, ERW, SAW/LSAW (depending on the selected material specification)

• Length: SRL / DRL / fixed length (project-based)

• Ends: Plain end, beveled end; threading when applicable

• Threading Note: Schedules 5 and 10 do not permit threading in accordance with ASME pipe thread requirements.

Key Features

1. Interchangeable schedule system for standardized wall thickness selection and global supply compatibility.

2. Supports welded and seamless pipe dimensional standardization for broad pressure/temperature service.

3. Clear designation rules (NPS/DN) used widely in industrial piping and pipeline design documentation.

Our Advantages

1) “Is ASME B36.10M a material standard or only a dimension standard?”

Answer: It is a dimension standard (OD, wall thickness schedules, mass). Material compliance is ensured by ordering the pipe to a material specification (e.g., ASTM A106, ASTM A53, API 5L, ASTM A333, ASTM A335) while keeping B36.10M dimensions. This avoids specification mismatch at inspection and site acceptance.

2) “How do I choose the right Schedule for pressure and fabrication (threading, welding, etc.)?”

Answer: B36.10M provides the standardized Schedule/STD/XS/XXS framework for wall thickness selection, while pressure design is finalized by the project code and material strength. We support buyers by confirming Schedule availability, end preparation, and threading feasibility—including the key limitation that Sch 5 and Sch 10 are not suitable for threading.

3) “How can I ensure cross-standard equivalence for international projects (EU/RU/JP/CN)?”

Answer: We can align dimensional and documentation expectations by referencing regional counterparts for dimensions and typical pipe usage standards:

• EU: EN 10220 for dimensions/mass tables (with EN material standards as required).

• China: GB/T 17395 for steel tube dimensions/shapes/masses/tolerances.

• Russia / Japan: common pipe standards (GOST/JIS) can be mapped in the PO and MTC package to support inspection and customs acceptance.

Application Areas

General Industries: oil & gas, petrochemical, power generation, water treatment, construction, HVAC, and general process piping.

Where it is used (examples):

• Oil & Gas: gathering lines, plant piping, utility piping, some pipeline components (grade/spec dependent)

• Petrochemical/Chemical: process lines, steam/condensate lines, instrument air headers

• Power & Energy: boiler auxiliary piping, high-temperature lines (alloy grades as required)

• Water & Utilities: water transmission, fire protection headers (standard and spec dependent)

• Construction/Industrial: structural and mechanical piping runs, pipe racks, supports (when allowed by project spec)
