SS 310 Seamless Pipe Weight Chart

The weight of Stainless Steel 310 Seamless Pipe depends mainly on its outside diameter, wall thickness and pipe length. Heavier schedules have greater wall thickness and therefore result in higher weight per metre. Actual supplied weight may vary according to dimensional tolerances and manufacturing requirements.

Pipe Size Typical Schedule Approx. Weight
1 Inch SCH 40S Approx. 2.09 kg/m
2 Inch SCH 40S Approx. 5.44 kg/m
3 Inch SCH 40S Approx. 7.67 kg/m
4 Inch SCH 40S Approx. 10.79 kg/m
6 Inch SCH 40S Approx. 16.10 kg/m

For accurate SS 310 Seamless Pipe weight calculations, the exact outside diameter, wall thickness and length should be considered. Weight can also vary depending on the applicable dimensional standard.

SS 310 Seamless Pipe Schedule Chart

Stainless Steel 310 Seamless Pipes are available in different schedules to accommodate varying pressure, temperature and mechanical service requirements. The selected schedule determines the nominal wall thickness for a particular pipe size.

Schedule Typical Description Application Consideration
SCH 5S Light wall Suitable for specified low-pressure services
SCH 10S Light to medium wall Process and utility applications
SCH 40S Standard wall range General industrial piping
SCH 80S Heavy wall Higher pressure service requirements
SCH 160 Extra heavy wall Specified demanding pressure applications

ASTM A312 TP310 Seamless Pipe

ASTM A312 TP310 Seamless Pipe is manufactured from Type 310 austenitic stainless steel according to the applicable ASTM A312 requirements. This specification covers seamless, welded and heavily cold-worked austenitic stainless steel pipe intended for corrosive and high-temperature service.

SS 310 seamless pipe supplied to ASTM A312 requirements can be selected in different sizes, schedules and wall thicknesses depending on the application. The applicable edition of the specification, dimensions, testing requirements and supplementary requirements should be confirmed before procurement.

For ASME applications, the corresponding material designation may be referenced as ASME SA312, subject to the applicable Code and project requirements.

SS 310 Seamless Pipe Chemical Composition & Mechanical Properties

Stainless Steel 310 is an austenitic chromium-nickel stainless steel with a composition designed to provide strong oxidation resistance and useful performance in elevated-temperature environments.

Element Typical / Specification Range
Chromium 24.0–26.0%
Nickel 19.0–22.0%
Carbon 0.25% max.
Manganese 2.00% max.
Silicon 1.50% max.
Phosphorus 0.045% max.
Sulfur 0.030% max.
Iron Balance

SS 310 Seamless Pipes provide good tensile strength, yield strength and elongation in accordance with the applicable product specification. Mechanical properties can vary with product form, heat treatment, dimensions and the specific standard or specification being followed.

SS 310 vs SS 310S Seamless Pipe

SS 310 and SS 310S are closely related austenitic stainless steel grades used for high-temperature applications. The main difference is the carbon content, with 310S having a lower maximum carbon level than Grade 310. This difference can influence fabrication and service considerations depending on the application.

Feature SS 310 SS 310S
UNS S31000 S31008
Carbon Higher maximum carbon content Lower maximum carbon content
Temperature Service High-temperature applications High-temperature applications
Oxidation Resistance Excellent Excellent
Selection Based on applicable service requirements Often selected where lower carbon is preferred

SS 310 Seamless Pipe vs Welded Pipe

Both seamless and welded stainless steel pipes can be used in industrial applications, but their manufacturing processes are different. 310 SS Tubing is produced from a solid billet, while welded pipe is manufactured from a plate or strip that is formed and joined along a longitudinal seam.

Feature SS 310 Seamless Pipe SS 310 Welded Pipe
Manufacturing Produced from a pierced billet Produced from formed strip or plate with a welded seam
Longitudinal Seam No welded longitudinal seam Contains a welded longitudinal seam
Size Availability Available in various standard sizes Wide range of sizes and larger diameters can be available
Typical Selection Selected where seamless construction is specified Selected where welded construction is suitable
