CRA’s Mill #16
CRA owns a second finishing mill that is currently being stored in the Houston area. We expect to have this mill fully operational in 2018. Its features include:

  • Purchased by CRA in 2011
  • Upgraded, refurbished and modernized in 2013
  • Manufactured by EZTM – Electriceskie Zavod Tiajelov Mashin
  • Production capacity: Up to 450,000 pounds per month / 2,450 metric tons per year
  • Size range: 3” OD to 13-3/8” OD
  • Max output length: R1, R2, R3, Lengths up to 52’

Our finishing mills will run all nickel, super duplex/ duplex, and chrome alloys.

While our manufacturing process and equipment is similar to that of other manufacturers, we manage the timeline of our operations differently than other mills to provide unique value to the market.

CRA’s finished tubes are manufactured by traditional methods. The material starts off as an ingot or continuous cast billet. It is then hot worked to achieve a sound wrought structure and converted to a hollow tube shell by hot working or trepanning. The choice of which process route to use is dependent upon several variables including quantity and the customer delivery need. The tube shells are annealed to obtain the required microstructure, cold pilgered to achieve the finish size and mechanical properties, straightened, non-destructive/destructive/visual testing, and then final cutting/inspection/marking.

In order to support our JIT Model we maintain feedstock at various stages which we can utilize rather than starting from melt. This significantly reduces our lead time and improves delivery reliability. We are also able to accommodate any key 3rd party inspection points or customer QA/QC requirements.

Quality is in our DNA. We have a 97.5% customer quality rating. We are ISO 9001:2008 certified and currently transitioning to the 2015 standard. The baseline for CRA manufacturing is API 5CRA. In addition, our technical and quality group are actively involved in several API subcommittees.

Our manufacturing processes have a long history of quality, our facilities are growing, and our capabilities are expanding.

Our model may be simple but it can provide huge value.
