Stainless Steel Flanges: Material, Dimensions and Pressure Class
Select stainless steel flanges by flange type, nominal size, dimensional standard, pressure class or PN designation, facing and material grade. ASTM A182 is a material specification for forged or rolled alloy and stainless steel piping components; it is not the flange dimensional standard. State ASME B16.5, EN 1092-1 or the applicable project standard separately.
Dimensions: ASME B16.5 / EN 1092-1 as specified; material separately
SS 304/316/316L/202
10 Grams to 40kg
Weld-neck, slip-on, blind, threaded and lap-joint flanges have different assembly requirements. Match the flange, pipe or stub end, gasket, bolting and mating face to the design. Confirm bore or pipe schedule, facing dimensions, bolt circle and surface finish.
ASME Class 150 is a class designation, not a universal 150 psi working-pressure rating. The allowable pressure depends on material group, temperature and the governing standard. PN designations also require the applicable pressure-temperature assessment.
For legacy drawings, identify the exact DIN reference and edition. Legacy DIN flange references have been superseded; use the edition specified by the project. Confirm replacement dimensions against the applicable EN 1092-1 type and PN requirements rather than assuming interchangeability.
For an ASTM A182 flange, specify the applicable grade, such as F304, F316 or F316L, and all required heat-treatment and testing conditions. Cast components require an appropriate casting specification and cannot be represented as ASTM A182 forgings. Confirm service suitability, especially for chloride-containing fluids.
Provide flange type, size, standard, pressure class or PN, facing, bore, alloy, quantity and design conditions. State material certification, dimensional inspection, non-destructive examination and any project-specific testing requirements. Manufacturing capability, finish and delivery are confirmed in the quotation.
Stainless Steel Flanges is a pipe or tube fitting used in plumbing, process and instrumentation systems. Final suitability depends on the approved specification and application conditions.
Typical applications include plumbing, process and instrumentation systems. Confirm load, environment, mating parts and applicable standards before selection.
Specify brass, stainless steel or another compatible alloy. State the exact grade because similar commercial alloys can differ in composition and performance.
Standard and custom sizes can be reviewed from pipe or tube size, thread, seal type and pressure class. Nominal size alone may not define compatibility.
Provide pipe or tube size, thread, seal type and pressure class, with units, tolerances and drawing revision.
Yes. Custom geometry, threads, tolerances and features can be assessed from a dimensioned drawing or approved sample.
Relevant Metric, BSP, BSPT, NPT, NPTF, PG, BA or BSW threads may be considered. Specify form, size, pitch, class and engagement length.
Options may include natural, plated, polished or passivated. Specify coating type, thickness, appearance and corrosion or conductivity needs.
Tolerance depends on material, size, geometry and process. Mark critical dimensions and fits clearly on the drawing.
Check mating dimensions, orientation, sealing or retention method and specified tightening torque before use.
Inspection can cover material identity, critical dimensions, threads, finish and drawing-specific functional checks.
Material certificates, dimensional reports and coating or test records can be agreed at quotation stage.
Prototype or pre-production samples can be reviewed for new custom parts, subject to tooling and material requirements.
Minimum quantity and lead time vary with material, size, tooling, finish, inspection and order volume.
Provide the drawing or specification, material, dimensions, tolerances, finish, quantity, inspection, packing and destination.
