Albina just bent and welded 27 lengths x 20 ft to make 3 cooling coil assemblies for a refrigeration project. All material processed was 1¼” Sch80 SA106B seamless.
Albina roll bent the material to the requested coil configurations. We trimmed the coils to size and draw bent the terminals and welded the terminals to the coils. Each cooling coil assemble was pressure tested after fabrication for leaks. Once we completed this project we shipped it across the country to Maryland!
Does traffic frustrate you? Are you tired of facing poor road conditions and various road hazards when driving?
Albina is teaming up where ever we can with contractors to provide bent steel for new road construction. New roads in high traffic areas will help alleviate traffic congestion and will provide commuters with better roads and driving conditions.
One such area in Oregon that has historically had very high congestion is the highway connecting the cities of Newberg and Dundee. Certain times of the day this highway sits at a standstill. Fortunately, there is a new Bypass road being built that will help with the heavy traffic congestion.
Albina will be providing the bent steel for the new Newberg Dundee Bypass. Materials include:
TS 10″ X 4″ X .375″ WALL A500 GR B
TS 12″ X 8″ X .375″ WALL A500 GR B
Materials are bent the Hard way to various configurations. All materials are bent to AESS (architecturally exposed structural steel) standards. For more information on the project you can read a recent update posted on Oregon.gov.
Albina spiral coiled ½” OD X .065″ WALL stainless steel tube heat exchanger for an industrial application. We were supplied with only the existing coil to reproduce from. The coils were bent in one continuous piece that spirals down on the inside and then steps out and spirals back over itself. The sheet between was not needed to complete the bends but was left in place to match the existing design.

Albina is currently bending:
259 lengths x 20 ft of 3/4″ OD X .049″ WALL T304 S/S.
279 lengths x 33 ft of 1″ OD X .049″ WALL ASTM B338 GRADE 7 SMLS
858 lengths x 30 ft of 1″ OD X .065″ WALL Zr702
For these heat exchanger “u-tube” projects we bend to various radii configurations and all bends are at 180°. After bending, we always trim both ends of the bend, deburr the ends after trimming, wash the ID of the tubing and securely package the bent tubes in custom made wooden crates. All of the bends are bent and checked to RDB-2.31 and ASME Section II-B, SB-163, S1.2.3 standards for wall thinning and ovailty. If high quality bends that won’t fail are required, industrial companies know to come to Albina. Do U? See some U-Tube bends below.

Albina is much more than just a structural bending facility. We service ALL industries that might require bent steel.
Recently Albina was involved with a large industrial application where we orovided Cargo Heating Pipe Coils for tanks in barges.
We were responsible for bending, trimming and washing each of the 488 lengths x 40 ft 2″ SCH40 SA106B SMLS to net 880 pcs. All bends were made to a 6” center-line-radius and our quality control department had to 100% QC parts to make sure the backwall thinning of the material was not below .079” and that ovality of the material was minimized.
After processing the first phase of this project the customer immediately placed 3 more releases as they were pleased with the quality, fair pricing, communication and customer service offered by Albina.
While we would prefer a bridge to be constructed of mostly curved steel, steel can still add value in the construction of a concrete bridge. Post-tensioning is a form of “prestressing”, meaning that the steel is stressed (pulled or tensioned) before the concrete has to support the service loads. A typical steel strand used for post-tensioning has a diameter of 15.7mm and a tensile strength around four times higher than an average non-prestressed piece of rebar. Albina completed a recent project consisting of 300,000# of 3-1/2″-5″ OD pipe bent, cut, trimmed, weld marked and galvanized for thousands of pieces for a post tensioning piping (conduit) for a local bridge project. Our bent steel is then placed in a sheath or duct. This allows it to move as necessary when the tensioning force is applied after the concrete cures. The steel stretches as it is tensioned and it is locked into place, thus maintaining the force in the strand for the life of the structure.
