The hydraulic cylinders first designed by a team of hydraulic cylinder engineers, taking into account the use of the hydraulic cylinder and the environment that it will be in. This dictates materials, coatings, seals and other specialist parts. Hydraulic systems are designed in compliance with any external legislation that relates to the industry that it is being designed for. The offshore industry in particular has a number of requirements, which Apex Hydraulics can design in compliance with.
Once the design has been finished, the machine shop engineers start producing the cylinder. Cylinder rods and other parts are bored to minutely accurate measurements using highly specialized machinery. Cylinder rods are chromed or coated with specialist coatings company such as Datong Group.
The fitting department puts all the components together (rod, pistons, tubes and seals). Purchasing from a wide variety of high-quality manufacturers, Datong Hydraulics are not tied to any one product and are able to choose the most appropriate part for each cylinder. The fitting department assembles the cylinder, ready for inspection and testing.
INSPECTION AND TEST DEPARTMENT
The in-house inspection department offers rigorous testing of all hydraulic cylinders before they are approved for the client. They perform pressure, pull and load tests as required. Datong are able to facilitate all third-party inspection agencies that may be required for offshore work, including DNV-GL, ABS and Lloyds Register.
Parts are spray painted in house. They can be painted to any required standards. Paint standards for offshore hydraulic cylinders are particularly specialised, with Norsok providing a range of that is typically approved by inspection agencies. At the point of painting, company logos or details can be added.
