ASTM A182 ANSI B16.5 304L 316L Casting Stainless Steel Flange
1. Application:
For seal or connect of pipe/tub-e lines
2. Material:
304,304L,316,316L,carbon steel or other material on request
3. Standard:
ANSI,DIN,JIS,BS,EN1092-1
4. Size:
DN15 (1/2″) to DN5000 (200″)
5. Type:
Threaded Flanges, Socket Welding Flanges, Blind Flanges, Other FlangesTypes’ Specification
Welding neck
1, Preferred for high-pressure, subzero or elevated temperature
2, Hub is tapered and bored to match pipe’s inside diameter so flow is not restricted, preventing turbulence and reducing erosion
3, Easily radiographed and provides excellent stress distribution
Slip-on
1, Not normally used in high-stress applications due to low hub and weld attachment
2, Silps over outside of pipe
3, Inside of flange welded at hub and end of pipe
Lap joint
1, Used where bolt alignment or access for cleaning is required
2, Similar to slip-on flange when used with lap joint stub end
3, Radius at intersection of flange face and bore to match lap joint stub end
Threaded
1, Used where welding would would be hazardous
2, Designed for low-pressure and non-cyclic applications
3, Bore is threaded to match pipe thread
4, Tapered to seal pipe and flanges
Socket welding
1, For small-diameter chemical processes, hydraulic and stream distribution lines
2, Similar to slip-on flange
3, Counter bore matches pipe bore, allowing unrestricted flow
4, Counter bore from hub side fits pipe’s outer diameter - can insert pipe in socket with fillet weld at hub
Blind
1, Used to close ends of piping
2, Has no bore
3, Permits access to sealed lines

ASME B16.9/ANSI B16.47 Blind Flange Forged Flange
A blind flange is a type of pipe flange used to seal the end of a piping system, pressure vessel, or valve opening. Unlike standard flanges, it does not have a bore (center hole), making it ideal for isolating or terminating pipelines.

ASME JIS ANSI factory customized flat flange DN10 ~ DN600 PN16 stainless steel 304 full penetration weld PL flange
1. International Standard Compliance, Global Compatibility Without Barriers
Compliant with mainstream international standards such as ANSI/ASME, DIN, GB, and JIS, with precise matching of bolt hole and sealing surface dimensions to overseas equipment.
Obtained authoritative certifications such as ISO and CE, with complete material reports (e.g., A182 F12/F316) and non-destructive testing reports, ensuring smooth customs clearance.
2. Upgraded Materials and Processes, Adaptable to Extreme Working Conditions
Available in carbon steel, stainless steel, alloy, and other materials, supporting customization for high pressure (Class 600+), high temperature (≤800℃), and corrosion resistance.
Precision machined sealing surfaces (RF/MFM/FF types), combined with high-quality gaskets, achieve “zero leakage,” suitable for core applications in petroleum, chemical, and natural gas industries.
3. Customization + Stock Availability, Flexible Order Response
Supports customization of parameters such as outer diameter, thickness, and number of holes, with flexible minimum order quantities to meet both small-batch trial orders and large-volume procurement needs.
Sufficient stock of conventional specifications, fast delivery within 7-15 days after payment, combined with international logistics solutions to shorten delivery cycles.
4. High Cost-Effectiveness + Full-Chain Service, Reducing Procurement Costs
Leveraging the advantages of a complete industrial chain, prices are 15%-30% lower than international brands, without intermediary markups.
Provides English technical drawings and installation instructions, with 24-hour after-sales support to solve overseas installation and maintenance problems. -

High Selling Custom Big Size 1/2″~72″Sch40 Sch80 Class150~900 High Pressure General Industry Blind Stainless Steel Flange
Flange,also called flange disc or flange. The flange is a part connected between the shaft and the shaft, which is used for the connection between the pipe ends; It is also useful in the flange on the import and export of the equipment for the connection between two devices, such as the reducer flange. Flange connection or flange joint refers to a detachable connection which is connected by flanges, gaskets and bolts as a group of combined sealing structures. Because the flange has good compr... -
