A method for renovating the interior of a hollow structure such as a sewerage pit (1) is described. The method provides an access opening (16) to the hollow structure (1); provides a plurality of material sheets (3) comprising reinforcing fibers and a curable resin composition through the access opening (16) and against a wall (11a, 11b) of the hollow structure (1); and provides an inflatable pressure means (4a, 4b) within the hollow structure (1). The pressure means (4a, 4b) are inflated against the wall (11a, 11b). A curing means (6) is then provided within the hollow structure (1) for curing the resin composition; and the resin composition is cured to harden the material sheets and provide a renovated interior of the hollow structure (1).

Customized and selective decoration of internal tube-like surfaces using pre-printed films with splinter resistant property

Methods and systems of customized and selective decoration of internal tube-like surfaces using pre-printed films with splinter resistant property are described. The method of adhering a film to an internal surface of a tube-like structure. The structure may have a hollow interior defined by the internal surface. The method may be carried out by providing a pre-printed film comprising first and second sides and an adhesive layer adhered to at least a portion of the first side. The pre-printed film may be positioned at least partially within the hollow interior with the adhesive layer positioned adjacent to the internal surface of the tube-like structure. The adhesive layer may be adhered to the internal surface of the tube-like structure.

Bioinert piping

A bioinert piping (1) that has a flow path (2) provided inside and a main body portion (10) between end portions (8, 8) includes a resin tube (4) that forms an inner wall of the flow path (2) over an entire length of the flow path (2), and a metal tube (6) that accommodates the resin tube (4) inside so as to cover the outer peripheral surface of the resin tube (4) over at least an entire length of the main body portion (10). The metal tube (6) is plastically deformed toward an inner side so that the outer peripheral surface of the resin tube (4) and an inner peripheral surface of the metal tube (6) are in liquid-tight contact with each other.

PIG FOR USE IN A SYSTEM FOR LINING DUCTS
20190234551 · 2019-08-01 ·

The present disclosure relates to a pig which is insertable at least partly within a fabric liner sleeve located in a duct and which is capable of heating the liner sleeve in situ in the duct to melt thermoplastic material of the liner sleeve to form, on subsequent cooling of the melted thermoplastic material, a rigid liner in the duct.

The pig comprises: a gas inlet (1008) for receiving pressurised gas; a heating chamber (17) in which the pressurised gas is heated; and a gas outlet (1009) via which pressurised gas heated in the heating chamber (17) is deliverable to the fabric liner sleeve.

The pig comprises a tree diffuser (15) located in the heating chamber (17) via which pressurised gas can be delivered into the heating chamber (17).

The tree diffuser (15) has a plurality of branch pipes (A,B,C) each comprising at least one gas delivery aperture, each branch pipe (A,B,C) extending outwardly from a trunk portion of the tree diffuser (15).

Pipe liners and the installation thereof
10359143 · 2019-07-23 · ·

A pipe liner has an elongate duct of thin laminated thermoplastic layers and remains relatively flexible and folded to a flat form. In this form, opposing sides of the duct are pressed into close proximity aided by folding of the duct, so the liner can be stored efficiently. In use, the liner is inserted into a pipe. The liner is subsequently heated and pressed against the inner surface of the pipe to form a close fit. Once the liner cools, it sets in place providing a close fitting pipe lining. In order to ensure adequate and even heating of the pipe liner during installation, heating is provided within the liner. The heating may comprise: a plurality of conductive filaments; electromagnetic susceptor material; or a plurality of magnetic particles.
