Abstract:
The invention concerns a threaded tubular component for drilling or working hydrocarbon wells, said tubular component having at one of its ends (1; 2) a threaded zone (3; 4) produced on its outer or inner peripheral surface depending on whether the threaded end is male or female in type, in which at least a portion of the end (1; 2) is coated with at least one lubricating dry film (12) comprising at least 65% by weight of a polyaryletherketone. The invention also concerns a process for depositing said film (12).
Abstract:
The object of the invention is a traction sheave elevator and a rope (3) that contains metal as a load-bearing material, such as the suspension rope of an elevator, which rope comprises at least one or more strands (7) laid from metal wires (9) and which rope (3) is lubricated with a lubricant (8). Another object is the use of the aforementioned lubricant for lubricating the rope (3). The lubricant (8) comprises at least oil and thickener, which thickener in the lubricant (8) comprises at least 10% or more of the mass of the lubricant (8).
Abstract:
The invention relates to an anticorrosive agent for metal components. In order to provide an environmentally compatible anticorrosive agent which can be applied to metal components without components having to be freed of the anticorrosive agent before installation, allows good coating even on oily surfaces, has a great anticorrosive effect and is also compatible with aqueous lubricant compositions, the anticorrosive agent of the invention comprises (in percent by weight): a) more than 50% water, b) a surfactant; c) a boric acid derivative; d) a platelet-like or rod-like filler; e) optionally a binder; f) optionally a carboxylic acid salt.
Abstract:
Die Erfindung betrifft eine wässrige Graphitdispersion, umfassend Graphitteilchen, Stabilisatoren, Additive und Wasser, wobei die Graphitteilchen in dem Wasser dispergiert sind und die Stabilisatoren als Dispergiermittel vorgesehen sind. Die Erfindung zeichnet sich dadurch aus, dass die Oberfläche der Graphitteilchen zumindest abschnittsweise kugelförmig ausgebildet ist.
Abstract:
Die vorliegende Erfindung betrifft eine stabile wässrige Dispersion von Partikeln, wobei die Partikel im wässrigen Medium durch einen polymeren Stabilisator stabilisiert werden. Der Stabilisator ist ein Polycarboxylat.
Abstract:
A coating and bonding composition is disclosed which includes a suspending agent, bonding agent, thinning agent, and a particulate fluoride anti-seize agent designed to bond a particulate fluoride film to the thread surface to prevent seizing and galling. A anti-seize/lubricating composition is also disclosed where an environmentally friendly lubricating composition is applied as a top coat to the bonding composition and to methods for making and using the compositions.

Abstract:
The invention relates to a swellable phylloscilicate on the basis of smectite or sepiolith/palygorskite for use in media that reduce swellability and that contain bivalent or polyvalent cations, characterized by a swelling volume of about 5 to 50 ml, measured by adding 2 g phyllosilicates (absolutely dry) to 100 ml water, and by a fineness of maximally 5 % by weight > 40 mu m or maximally 20 % > 20 mu m, as the dry screening refuse.
