A&A expands global high-pressure tube reach

A&A Machine & Fabrication, LLC announced today that they have received their first orders for high pressure tubing from across the oceans. That’s both oceans, the Atlantic and Pacific. A&A recently received orders for large low-density plastic plant projects requiring high pressure tubing from both Spain and South Korea.

A&A has long been a leader in the low-density, high-pressure, tubular reactor market in the US. But they have been working on growing their global market share, and particularly in Europe, for several years now. In 2015 they signed an agreement with TimkenSteel (Canton, Ohio) to market, sell and produce high pressure tubing (HPT) for use in the manufacture of low-density polyethylene. A&A then further manufactures the tubing into a final product for use in plastic plants. When users of the HPT in the US found out about the domestic supply of high-quality tubing with significantly shorter lead times, A&A began receiving orders. Now companies overseas are also realizing the benefit of coming to A&A for this product group, where they can get globally competitively priced steel with quicker lead times, leading to shorter plant startup or expansion projects. A&A has also recently received news that the TimkenSteel provided tubing has now received approval to be written into the material specification of another major client. This makes the fifth (5th) major user of the high-pressure tubing on the global market to write the special material into their specification since 2015.

C. Alan Hutchins, President & CEO, states, “Our global path to more market share is now clearer than ever before and we are prepared to march forward on the path. The ability to get the tubing made, tested and approved with five major clients has taken over 4 years. We have sold it domestically and to Argentina (South America), but this is the first time we have been able to win a project away from our competitors in Europe; in what I call their back yard. That’s a significant event for us. This sets A&A up for more exposure to the global high-pressure tube market and we are excited to do that right here from La Marque, Texas.”

Kraig Warren, Vice-President of Fabrication & Engineering, has guided, led and drove this project from infancy toward this significant event. Kraig Warren commented, “It has been a long, hard road, but the results are exciting for A&A and the clients we supply tubing to. This whole process and the tube supply chain is not an easy one to manage and these tubular reactors are difficult and complex products we build, but we are proud to gain the confidence of these overseas clients and we excited for the future of the market.”

In June 2018, A&A completed Phase I of its site expansion at 3101 Texas Avenue in La Marque, TX. The increased footprint will allow A&A to meet growing customer demands for larger hardware and equipment and increase efficiency of the company’s unique manufacturing and fabrication processes. The expansion consisted of purchasing additional property along the southwest side of our facility, excavating a detention pond, pouring a new parking lot, and relocating the laydown yard. This now allows Phase II, adding additional enclosed manufacturing floor space, to begin.

In November 2017, A&A performed a field service repair of an Ethylene Oxide/Ethylene Glycol (EOEG) mixer in Kuwait City, Kuwait. The required replacement parts were manufactured at A&A’s facility in La Marque, Texas. Prior to install, the parts, necessary consumables, and quality control documentation were shipped to the end-users’s facility where A&A’s field service team, led by Andy Kallinger, completed the repair, final assembly and NDE testing during the scheduled turnaround. As the original manufacturer of the unit and technical experts on the fabrication and assembly of EOEG systems, the repair work was successfully completed in the timeframe required by the customer.


Kraig Warren, A&A’s Fabrication & Engineering Manager, recently attended the 2017 ASME PVP Conference held from July 16-20, 2017 in Waikoloa, Hawaii. At the conference, Mr. Warren presented ASME paper PVP2017-65223 titled High Pressure Tubing Material Performance Review that discussed the qualification process and results for HS220-27-Ca4 High Pressure Tubing material that is manufactured by TimkenSteel. The qualification included fatigue testing to ASME Section VIII Division 3 Article KD-3, which consisted of cycle testing samples up to 1,000,000 times over pressures ranging from 40-65 ksi. A Leak-Before-Burst test was also performed on a specimen that was intentionally ran to failure in order to ensure that the result was a pin-hole leak rather than a catastrophic burst. In addition, A&A processed the material to autofrettage requirements set forth in ASME Section VIII Division 3 Article KD-5. A&A was able to prove that the HS220-27-Ca4 material was able to meet ASME requirements and industry specifications for use in the manufacture of Low Density Polyethylene (LDPE) plastics.

A&A and TimkenSteel have gained market acceptance of this product as multiple end-users have purchased the HS-220-Ca4 material from A&A for use in their LDPE processes. A&A and TimkenSteel continue to jointly market this product to users as a reliable, cost-effective and short lead-time item.


Striving to remain a leader in LDPE High Pressure component manufacturing, A&A now has the ability to provide rolled threads for your LDPE equipment, as an in-house service. 

Thread rolling is a cold forming process that can be performed on ductile metal, a process that has been around for more than one hundred years. Thread rollers come in a variety of types and sizes, but they all use a mechanism where hardened steel dies, or rolls, are matched and set to penetrate, with force, in order to reshape the material surface of a round diameter into a thread form. Formed threads are preferred for high strength and critical applications like those found in the petro-chemical industry. Threads that are rolled, especially on heat treated parts, have higher tension, shear, and fatigue strength. No material is removed during the rolling process, eliminating one of the inherent weaknesses of cut or ground threads. No tool marks or stress risers occur during thread rolling. The cold formed properties include a higher density of material grains, or molecules, especially where they have been compacted along the lower flank of each thread pitch and in the root of the thread.

Studs, bolts, compressor piston rods and certainly LDPE HP tubing, which represents one of A&A's niche capabilities, are a few examples of parts which our customers prefer their threads rolled. Our tooling list for this technology at present allows for the rolling of various size threads between 7/8" to 5". Watch the video below and see this new capability in action.


In keeping with A & A's policy of always improving technology, we have acquired a new, state-of-the-art autofrettage system for better serving our customers needs. In 1975, A&A began autofrettage service with a pneumatic-driven autofrettage pump system that was rated at maximum pressure of 175 ksi. In 1999, we added a second unit that utilized hydraulic drive rated at 200 ksi. In July of this year, we replaced our original unit system with a hydraulic autofrettage system that is rated at 17ksi. This unit incorporates the latest technology including digital data input, computer-generated data forms, and real-time pressure charts.


A & A Machine Fabrication, LLC announced today that they have signed an agreement with TimkenSteel (Canton, Ohio) to market, sell and produce high pressure tubing (HPT) for use in the manufacture of low density polyethylene. For many years, the supply of this special thick-wall tubing could only be found in Europe, where lead times were long and the product was expensive for North American buyers. Now, the buyers and users of the HPT can find a high quality U.S. supply with significantly shorter lead times. A&A has also just received approval from its first client for the supply of HPT from TimkenSteel.

C. Alan Hutchins, President & CEO, states, "This agreement will position us and TimkenSteel for the future growth in North America and other parts of the world for HPT supply. Users of the tubing will be able to plan projects with a more accurate forecast due to the shorter lead times, ease of inspection and oversight of the manufacturing process.

Kraig Warren, A&A Fabrication & Engineering Manager, guided, led and drove the project to completion. Starting in January 2013, the project required numerous conferences and voluminous data collection through manufacturing and testing of the tubing. Kraig Warren commented, "It was a long, hard road, but the results are exciting for the industry and its future growth. We learned valuable information about the tube making process and HPT chemical and mechanical characteristics.


A & A recently completed eight modular process skids that play an integral part in the manufacturing of polyethylene. Two of the skids will be shipped to China and the other six are for domestic production. These modular process skids represent the uniquely combined precision machining and fabrication skills of our company.


As we continue to grow our customer base and Always Available brand, A&A attended the SynGas Association 2015 conference in Tulsa, Oklahoma, April 20-22. Various producers and suppliers of the Synthetic Gas Industry were in attendance. Keynote speakers discussed various details of the SynGas processes and several technical seminars were made available to attendees.
