What is a Raised Face Weld Neck Flange?
A raised face weld neck flange is a commonly used type of flange in piping systems, especially for high-pressure and high-temperature applications. It features a combination of a weld neck flange and a raised face, both of which enhance the sealing capabilities when connected to pipes or other components.
Key Features:
-
Weld Neck Flange:
The weld neck flange has a long, tapered neck that is welded directly to the pipe. This neck design provides additional strength and a smooth transition from the pipe’s material thickness to the flange, making it ideal for high-pressure applications.
-
Raised Face:
The raised face is a slightly elevated area around the bolt holes of the flange, which helps create a better seal between the flange and gasket. The raised portion typically stands about 1/16 inch (1.6 mm) above the surface of the pipe, ensuring more gasket contact for a stronger seal and minimizing leakage risks.
-
Material and Construction:
Raised face weld neck flanges are made from materials such as carbon steel, stainless steel, or alloy steel, selected to match the specific requirements of the transported fluid or gas.
-
Bolt Holes:
Bolt holes are positioned around the raised face to allow the flange to connect to other components or flanges. The number and size of these holes depend on the size and pressure rating of the flange.
Applications:
-
High-Pressure Systems:
These flanges are ideal for systems subject to high pressure, such as in the oil and gas, chemical processing, and power generation industries.
-
Steam and Water Pipelines:
Raised face weld neck flanges are often used in steam and water systems, where maintaining a reliable seal under pressure is critical.
-
Heat Exchangers and Pumps:
They are commonly used in heat exchangers, pumps, and machinery requiring strong and durable connections.
Benefits:
-
Strong, Pressure-Resistant Seal:
The raised face provides an effective seal with the gasket, reducing the chances of leaks.
-
Enhanced Strength:
The weld neck design helps evenly distribute stress along the pipe and flange, making it suitable for high-pressure and temperature environments.
-
Durability:
The combination of the weld neck and raised face features improves the overall durability and reliability of the connection, even in demanding conditions.

Shipping Policy
To ensure your order is shipped safely and appropriately, we determine the shipping method based on weight, size, and handling requirements.
Parcel Shipments
Smaller items that meet standard carrier limits are shipped via common parcel carriers such as UPS, FedEx, or USPS. This is calculated for you automatically at checkout.
LTL Freight (Less-Than-Truckload)
Orders that:
Weigh over 150 lbs, or
Exceed parcel carrier size or dimensional limits
will ship via LTL freight.
LTL shipments are handled by third-party freight carriers and typically involve palletized delivery. Transit times and delivery scheduling vary depending on carrier availability, destination, and freight class.
Please note:
LTL deliveries often require a delivery appointment.
Liftgate service, limited access, or residential delivery may affect transit time and cost.
It is best to reach out to us before your purchase on items that exceed 150lbs or that are larger than 96 inches in any one direction in order to ensure that you get an accurate estimate on cost.
Full Truckload (FTL) / Specialized Freight
Large or specialized items—such as tanks, vessels, oversized equipment, or shipments requiring hazmat handling or oversized permits—are managed directly by Tri-State Supply.
These shipments may require:
Full truckload (FTL) transport
Oversized or overweight permits
Specialized carriers or equipment
Additional coordination prior to shipment
Because of this, processing and delivery timelines for full truckload or specialized freight are determined on a case-by-case basis. Our team will coordinate directly with you to confirm logistics before shipment. You will need to reach out to us for a quote. You may also arrange freight for your purchases. Loading fees, appointments, and more arrangements will still need to be agreed upon before something leaves our property.
Order Processing & Timing
Most in-stock orders are processed within 1–3 business days. Freight shipments—especially LTL and full truckload—may require additional time to schedule pickup and delivery.
Estimated delivery dates are provided as guidance and are subject to carrier and logistical factors beyond our direct control.
