Founded in 1964 and located in Mineral Ridge, Ohio and Houston, Texas, SPT is a value-added supplier of large diameter, heavy wall mechanical pipe and tubing.

The Company’s technical expertise, product portfolio, and service offerings have created a dedicated customer base of manufacturers and distributors that continues to expand over time. SPT supplies niche sizes of tubing and pipe in both 1026 seamless carbon and 4140 seamless alloy.


“We are excited to partner with Crest Rock who shares our values and our vision for growth and innovation,” said Steve Baroff, President of Specialty Pipe & Tube. “As we celebrate our 60th year in business, we’re thrilled to be starting this new chapter with the same independent spirit that was instilled in the Company when it was founded back in 1964.”

“SPT’s history of excellence, range of products, and value-added services provide exceptional value to its customers,” commented Steve Johnson, co-founder and Partner at Crest Rock. “The Company’s premium, domestic and DFARS compliant products, technical expertise, and top-notch customer support have resulted in thousands of long-term customers who have remained loyal to the Company, in many cases for several decades. SPT’s partnership approach has differentiated them in the hot rolled seamless industry as they help their customers navigate a challenging supply chain environment by offering readily available inventory and consistently reliable shipping performance.
