Our Services
At Stratford Engineering® we offer a wide range of industrial engineering and equipment design services. With close to 100 years of experience, we have the expertise and know-how to help meet your needs.
Mechanical Seals
The advanced materials used throughout the seals are coupled with unparalleled design concepts aimed exclusively at the unique ALKYLATION requirements.
Always privately held, Stratford Engineering, LLC. began licensing ALKYLATION technologies in 1938. In 1977, Ward Graham, my father, bought controlling interest of Stratford Engineering® and rebuilt and expanded under the new name of Stratford/Graham Engineering which later became STRATCO, Inc. In 2003, the ALKYLATION division of STRATCO, Inc. was sold. We are here to help you in your reliability programs so that you can achieve the best, world class ALKYLATION performance.
Our newest seal systems are tested prior to shipment which assures successful operation. The seal designs offered are the product of 71 years of application experience supporting the global ALKYLATION community. The worldwide refining industry has made many changes in operations over the years, related to reliability, safety, and capacity. All of these issues demand continuous improvement in all areas.
Our seals address the needs of refineries in today’s tough business climate, with increased operating demands and a competitive environment.
The Stratford seals offer safety, redundancy, and improved operational life while addressing emissions levels and the long MTBR expected by today’s users.
Our Team is here to serve your Alkylation needs. Let us replace your mechanical seals with a Stratford seal!

Plant Design
Alkylation is the transfer of an alkyl group from one molecule to another. The alkyl group may be transferred as an alkyl carbocation, a free radical, a carbanion or a carbene (or their equivalents). Alkylating agents are widely used in chemistry because the alkyl group is probably the most common group encountered in organic molecules. Many biological target molecules or their synthetic precursors comprise of an alkyl chain, with specific functional groups in a specific order. Selective alkylation, or adding parts to the chain with the desired functional groups, is used, especially if there is no commonly available biological precursor.
In oil refining contexts, alkylation refers to a particular alkylation of isobutane with olefins. It is a major aspect of the upgrading of petroleum.
