Proprietary Wellhead Gaskets
Proprietary wellhead gaskets and seals are critical components used in both subsea and surface applications. Predominately, these parts are manufactured from all types of steels, stainless steels and high nickel alloys and are manufactured to very strict tolerances. Lone Star manufactures all our customer's proprietary wellhead gasket requirements on CNC machine tools in both the US and the UK. Currently, we operate over 20 different machine tools, ranging from small diameter bar-fed machines to large horizontal CNC lathes.
Many of the proprietary gaskets and seals we manufacture are plated or coated. Carbon steel rings are usually zinc plated or Zylan coated, while other seals of more exotic materials tend to be silver plated. On designs requiring primary and secondary elastomer seals, the seals are fitted after the main gasket body has been coated.
During the manufacturing process, our engineers are constantly checking, measuring and inspecting the part. This culminates in each proprietary part having to go through final inspection on a CMM and being dispatched with a CMM report. Lone Star have recently invested heavily in brand new, state of the art CMM hardware and software to ensure accuracy and reliability.
As with all our metal gaskets, our proprietary gaskets and seals are fully traceable using our unique heat code tracing system and are delivered with a full material certificates package.
Above all else, it if imperative that proprietary parts are manufactured to the customer's specifications. A deep understanding of the customer's requirements is paramount to the successful delivery of a part 'On Time' and defect free. This is where Lone Star has the edge over all our competition. We have been supplying the wellhead equipment manufacturers for over 10 years. Our understanding of the customer's requirements is unique, mainly due to the relationships we build with our customers. Our customers see us take an interest in their product. They hear us asking questions about what they want from a supplier and they see us responding positively to those requests.
