Overview
Taylor Forge Engineered Systems has been the innovative leader in the manufacturing of extruded connections since 1959. Gas transmission, petroleum, petrochemical and nuclear are some of the industries that have taken advantage of the superior qualities of extrusions. We can adapt our extensive experience in design, engineering, manufacturing, shipping and installation to meet your specific needs. Quality control is a fundamental concern due to the demanding environments in which our headers must perform.

Quality Assurance
TFES has more design and manufacturing experience than any other supplier. We do precise raw material testing including in-house destructive and non-destructive testing. Our closed die extrusion process assures control of interior and exterior wall shape.
In addition, extruded outlets allow for 100% radiographic examination of all welds.
Superior Strength
By moving the weld away from the highly stressed crotch area of the outlet, an extrusion offers a more reliable, proven connection than a welded-in or padded outlet. Fatigue cracking from cyclic or thermal loads is eliminated in some environments by extruded outlets. The butt weld of an extruded outlet also simplifies radiographic examination.
Design Flexibility
Extruded headers can offer design advantages unavailable with standard fittings. Outlet configurations can be designed to maximize cost savings or minimize space requirements. Specific specifications to meet stringent code requirements are easily achieved.
Cost Effective
Field labor costs are reduced with extruded headers. Girth welds between outlets are eliminated as are the attachment welds needed with reinforcement pads or welded connections. Because Taylor Forge manufactures both custom headers and a full range of standard fittings, we can recommend the most cost-effective solution to meet your system requirements.
Materials
High-yield materials are stocked in standard sizes with gages through 1 3/4”. Materials are able to achieve over 70,000 psi minimum yield strength. The material control department allots materials to each individual order, based upon order requirements and results of qualification tests.
Material Testing
- In-house, destructive testing is done on heat-treated specimens. The tests that can be performed are:
- Longitudinal and transverse tensile
- Longitudinal and transverse full-size charpy ‘V’ notch tests to -50° F; and Transverse full-size charpy ‘V’ notch tests at +20° F.
- Special tests for other special properties, or using a different heat treatment are performed when required.
Cutting
Materials are cut to size, beveled for longitudinal weld, and serialized for each different item. Serialization is maintained through the entire manufacturing process.
Rolling
TFES has in-house capabilities to either hot or cold roll 1/4” through 7 1/2” thick plates using one of five in-house rolling mills.
Welding
Our team of ASME Section IX qualified welders produce high quality fabrications.
Extrusion
Holes are torch-cut and conditioned in locations where extruded outlets are required. Dies are used inside and outside of these holes to control the outlet shape. Header sections are extruded cold or hot depending on exact plate chemistry or requirements. Header sections are annealed prior to cold extrusion. Extrusion may be pre-formed in several stages, with proper heat treatment between operations. Alternately, outlets may be extruded hot, or with a combination of hot and cold pulling.
Heat-treating
When the extrusion process is complete, the headers are normalized, normalized and tempered, or quench and tempered heat-treated. After heat treatment, in-house destructive or nondestructive tests can be performed.
Radiography
All longitudinal seams are completely radiographed in-house to verify weld integrity.
Stress Relief
Headers may be stress relieved. Where scraper bars are required, outlets are machined and bars installed prior to stress relief.
Blasting
Headers are either shot or sand blasted to a commercial finish.
Machining
All ends and outlets are machine beveled.
Identification
Headers are permanently marked using low-stress, interrupted dot-type stamps, unless otherwise specified.
Fabrication
Header assemblies can be furnished with flanges, pipes, and other fittings welded in position.
Finishing
Headers are final-inspected, prime-coated with black enamel or custom painted per customer specification, and prepared for shipment. Beveled ends are protected with end covers for shipping.
