Welcome to Core Pipe formerly known as Gerlin, Inc.

The Carol Stream, Illinois facility was opened in 1978 under the name Tube-Line Stainless Division of Hi-Shear Industries. It was designed specifically for the manufacture of stainless and alloy pipe fittings and flanges. Our current CEO and Chairman Joe Romanelli, Sr. was the original president of the division and main designer for the facility.

Gerlin, Inc. was founded in December, 1984 when the assets of Tube-Line Stainless Division were purchased from Hi Shear Industries. It is privately owned and operated by the Romanelli family.

In 1986, the original 65,000 SF building and land were acquired. This was done to secure a permanent location with the potential for future expansion. It did not take long for the future to start taking shape.

In October, 1987, Gerlin acquired the assets of Picor, a stainless fitting manufacturer located in Pennsylvania. Picor had a long history dating back to the early 1960's as a manufacturer of high quality stainless fittings in a variety of configurations. The acquisition of Picor expanded the manufacturing capacity and product lines of Gerlin to include Belled End, Long Tangent, Marine, and Brewery Quality fittings in addition to complimenting existing product lines of Tube-Line butt weld fittings and flanges.

In May, 1995, the stainless forming equipment of Ladish Company was acquired and moved from Cynthiana, Kentucky. The original Carol Stream facility was expanded to 85,000 SF with a high bay 20,000 square foot addition to accommodate this equipment, as well as additional large presses and state of the art heat treating equipment.

In September, 2005, Core Pipe Products, Inc. was formed as a subsidiary of Gerlin, Inc. to acquire the assets of Tubetec, Inc. in Sanford, Florida. The facility is located on approximately 12 acres and has more than 105,000 SF of manufacturing space specializing in large diameter stainless and alloy weld fittings up through 48" diameter.

In March, 2006, Gerlin introduced Brite Line as a new value product brand of stainless fittings and flanges produced globally by joint venture / manufacturing partners. The focus of the product line is on customers seeking a value product brand that has been manufactured using Gerlin quality standards and backed by the expertise offered by our management team.

Gerlin, Inc. is one of the premier manufacturers of stainless and alloy pipe fittings and flanges in the world. Our company has earned this reputation through the hard work and dedication of our employees who are truly our most valued asset. We will continue our future growth opportunities in product lines that will allow us to better serve our customers and provide a secure future for our employees and their families.
