By flange type
Choose by how the flange joins the pipe and carries the load. This is usually the first thing a piping class fixes, and the only choice that changes the shape of the part.
Forged Product Categories
Flanges are grouped by type; the standard, pressure class and material grade pages sit with them as specifications of any flange type. Forged components that no flange table covers have their own groups.
Product Catalogue
Flanges are listed by type, the one choice that changes the shape of the part. Any type can be made to your standard, pressure class and material grade; the pages for those specifications sit directly under the flange types. Forged parts that no flange table covers sit in the last two groups.

Forged FlangesThe entire forged flange range on one page - every type, every standard, every grade. Open this when you know the part is a forged flange but the type, standard or material is still being decided.Standard FlangesCatalogue flanges bought as line items: weld neck, slip-on, socket weld, threaded, blind and lap joint against ASME, EN, DIN or GOST tables. Open this for a bill of materials rather than one special part.

Standard, material and service condition are specifications of the flange, not separate products. Each standard page owns its own rating system - Class, PN, K or Ру - and each material page holds one cross-standard grade table; the pages below carry the tables, test evidence and document requirements for that specification.

Custom forged components
Forged parts controlled by a drawing instead of a flange table: rings, cylinders, wheels, bowls, tube sheets and round plates, branch outlets and one-off shapes.
Valve and pressure forgings3 product pages

Valve and pressure forgings
Pressure-bearing forged blanks for valve and flow-control assemblies - bodies, bonnets, valve tees and forged tees - quoted from the equipment drawing rather than a catalogue size.
Technical RFQ Routing Matrix
Start with the governing standard, service condition or material requirement, then send the listed data for technical confirmation before quotation.
| Your requirement | Technical check | Details to send | Product page |
|---|---|---|---|
| ASME flange specification | ASME B16.5 forged flange scope | NPS, class, facing, bore, material grade and quantity | ASME B16.5 Flanges |
| GOST / CIS specification | GOST forged flange scope | GOST reference, DN, PN, type, material and document scope | GOST Flanges |
| High-pressure service | Top rating band of the governing standard: ASME Class 600-2500, EN PN 100-400, JIS 30K-63K or GOST PN 100-250 | Standard and rating, RF or RTJ facing with ring number, material, hardness, NDT and heat-treatment requirements | High Pressure Flanges |
| Carbon or low-temperature steel | ASTM A105 or A350 LF2 suitability | Service temperature, impact-test requirement, class, MTC and inspection | A105 / LF2 |
| Stainless or duplex requirement | ASTM A182 stainless or project-specified duplex suitability | Grade such as F304/F304L or F316/F316L, corrosion service, PMI and MTC | Stainless and Duplex |
| Drawing-based forged component | Custom forging feasibility | Latest drawing, dimensions, material, machining, heat treatment and inspection | Non-Standard Forgings |
Use this matrix to prepare the first RFQ message. Final supply scope, material availability, inspection process and documentation are confirmed against your specification or drawing. See inspection and document requirements.
RFQ Review Focus
Send the standard or drawing, material grade, size, pressure class, quantity and inspection requirements; we check each before we quote.
By flange type: weld neck, long weld neck, slip-on, lap joint, blind, ring, square and anchor flanges
Specify any flange type by standard and pressure class: ASME B16.5, EN 1092-1 and DIN, GOST 33259 / 12820 / 12821, and Class 600 to 2500 high-pressure work
Specify any flange type by material grade: ASTM A105 and A105N, A350 LF2 for low-temperature service, and A182 stainless and duplex grades
Beyond flanges: rolled rings, cylinders, wheels, bowls, tube sheets, branch outlets, valve bodies and forged tees
