ANSI DIN Forged Class 150 Stainless Steel Slip On Flange
Our ANSI DIN Forged Class 150 Stainless Steel Slip On Flanges represent the premium standard in corrosion-resistant piping connections for diverse industrial applications. Manufactured from high-grade forged stainless steel to both ANSI/ASME B16.5 and DIN EN 1092-1 standards, these flanges offer exceptional durability, leak-proof performance, and compatibility with global piping systems. The slip-on design provides cost-effective installation while maintaining the structural integrity required for chemical processing, food & beverage, pharmaceutical, and marine applications.
The forging process ensures superior grain structure and mechanical properties compared to cast or plate alternatives, making these flanges ideal for demanding services involving corrosive media, temperature variations, and pressure fluctuations. Available in various stainless steel grades including 304, 316, and duplex alloys, these Class 150 flanges are engineered to provide reliable service in aggressive environments while offering easy installation and maintenance accessibility. Their dual-standard compliance makes them versatile components for multinational projects and equipment destined for global markets.

DIMENSION STANDARDS
PRODUCTION DETAIL SHOW
1. Face
Can be raised face(RF), full face(FF), Ring joint(RTJ) , Groove, Tongue, or customized.
2. Slip on with hub, flat welding. Also can offer slip on without hub.
3. CNC fine finished
Face finish: The finish on the face of flange is measured as an Arithmetical Average Roughness Height(AARH). The finish is determined by the standard used. For example, ANSI B16.5 specifies face finishes within a range 125AARH-500AARH(3.2Ra to 12.5Ra). Other finishes are available on requst, for example 1.6 Ra max,1.6/3.2 Ra, 3.2/6.3Ra or 6.3/12.5Ra. The range 3.2/6.3Ra is most common.
MARKING AND PACKING
• Each layer use plastic film to protect the surface
• For all stainless steel are packed by plywood case. For bigger size carbon flange are packed by plywood pallet. Or can be customized packing.
• Shipping mark can make on request
• Markings on products can be carved or printed. OEM is accepted.
INSPECTION
• UT test
• PT test
• MT test
• Dimension test
Before delivery, our QC team will arrange NDT test and dimension inspection.Also accept TPI(third party inspection).
