Power Generation & Industrial Plant Steel Castings

We have over 25 years of experience casting carbon steel and stainless steel valves and valve components for the power generation and industrial plants include globe valves, check valves, ball valves, butterfly valves (BFV), plug, rotary, safety, strainer, and gate valves. We also produce complex shaped steel castings for volute covers, pump casings, and impellers.


Our expertise in shell mold casting of various heat resistant and wear resistant steels allows us to maintain tight casting tolerances. Due to the ability to maintain close tolerances for products such as biomass incinerator grate bars, many of our clients have often found that minimal or no further post-casting machining process is required thus resulting in time and cost savings.

Steel Mill Casting Project Case: High quantity, strict quality steel castings under tight deadline

The biggest challenge for this steel casting project was the tight deadline that our client needed the castings by. Our US client was looking for a casting shop that was able to accommodate their aggressive deadline that most other shops were not able to accommodate. We had to tightly manage the project; we calculated the exact time that each process takes from wooden pattern design to manufacturing and casting production; then we ensured the process to make zero defects. We first shared our manufacturing schedule that outlined the number of end bells we were scheduled to finish each day from molding process, melting process, casting completion, LP inspection to shipment. We also reported our manufacturing process on a regular basis.

ShipmentArrival at Port


This client specifically required to carry out LP inspection to 100% of the castings under the requirement condition SPR-LPR/APR to NF EN 1371-1. Weld areas were to be cleaned up to SP3/CP3 standards, and LP3/AP3 to EN1371-1 (100% testing) when machined. Mechanical testing, chemical composition, and LP inspection were performed on 100% of the castings, and reports were sent for client’s review upon shipping. Material certificate was also to be reported for all steel castings with the heat treatment number written in visible location for each casting.

Manufacturing & Casting Process

Our foundry utilizes CO2, Sand Casting, and Shell Mold Casting processes. Depending on the size and shape of the casting, we are capable of producing sand castings up to 2,500 kg and shell mold castings up to 50 kg. Typical castings that we produce include components for valves, pumps, machinery, mining, train, and refuse biomass incinerator components.


Nondestructive testing (RT, UT, MT, PT) is performed in-house and with third-party NDT inspection companies with DNV-certified inspectors. Our in-house radiographic testing (RT) equipment includes x-ray, iridium (Ir-192), and cobalt (Co-60) gamma ray testing.
