Galbiati Group works alongside leading manufacturers for the supply of components for pump stations for oil, gas, air and water industries.
As far as the production of pump housings is concerned, the Galbiati’s Mechanical Machining Division has recently completed the machining of a subsea pump housing for the oil industry, consisting of a motor casing and a pump casing.
The pump housing was manufactured from high alloy steel castings, previously rough machined and with standard allowance material. The pump housing was then fully machined on a 7-axis controlled boring machine with a 65t capacity rototranslating table and equipped with a controlled d’Andrea head to perform turning operations.
The d’Andrea head (U TRONIC) used during the machining of the pump housing is a NC head that can perform diameters of up to 1,800mm, for external and internal facing operations and undercuts, internal or external conical and cylindrical boring and milling operations as well as complex profile machining via interpolation with the other machine axes.
Components were entirely processed through a dual cycle with intermediate tests carried on a Zeiss 3D coordinate measuring machine to check for the presence of any distortions, given the high malleability of the material. The dimensional test was carried out on ND (PT) control by qualified staff of the Galbiati company.
The final test, which took place in the customers’ presence, was carried out using Zeiss 3D measuring machine to guarantee the quality and high precision, to the customer’s total satisfaction.
