    Abstract: A connector assembly (608) for a length of corrugated tubing (601) having an inner corrugated element (602) and an outer flexible sheath layer (603). The connector assembly (608) comprises a fitting (609) including a fluid-flow passage and an abutment surface (612) for the corrugated tubing (601) to seat thereon; axial loading means operably connectable to the fitting (609), the axial loading means including a connector (613) and a collet (610), the collet (610) having a radially inward protruding clamping element (611) for insertion into a trough (606) of the inner corrugated element (602), and a sheath-contact portion (625) for engaging the outer sheath layer (603), so that, when the connector (613) moves the collet (610) into engagement with the fitting (609), the collet (610) causes the corrugated element (602) to move onto the abutment surface (612) whilst maintaining engagement with the outer sheath layer (603).The sheath-contact portion (625) is axially positionable between the inner corrugated element (602) and the outer sheath layer (603) of the corrugated tubing (601), in use.

    Abstract: The present invention disclosed a pipe connector assembly (20) for a metal-plastic composite pipe connection comprising a connector (25) configured to couple to a pipe end (35), a threaded reducer nut (40) configured to connect to the pipe end (35) and over a connection between the pipe end (35) and the connector end (25), a half coupling (45) configured to couple to a portion of the threaded connector end (30), and a nut (50) configured to couple to the threaded reducer nut (40) and over the half coupling (45). A continuity of the threads on the metal pipe (27) of the connector end (30) and the threads on the pipe end (35) are formed and that the crest of the threads on the pipe end (35) is position higher than the threads on the connector end (30) and that the crest of the threads on the metal pipe (27) is gradually taller towards the connector end (30).

    Abstract: A three layer PVDF coating system is provided for oil or gas pipe. The system comprises a steel pipe, an epoxy layer, for example, made from a high temperature liquid epoxy or a FBE, preferably a high temperature FBE, which provides excellent adhesion to the steel pipe and anti-corrosion protection, a maleic anhydride modified PVDF tie layer which provides excellent bonding to both FBE and PVDF topcoat, and substantially blocks water and oxygen degradation of the FBE by forming a protective, bonded, coating overtop of the FBE, and a PVDF layer which provides a further excellent water and oxygen barrier, as well as excellent mechanical protection. Also provided is a method of manufacturing a pipe having said coating system.
