A corrosion resistant jacket for insulated pipes and components includes an outer polymeric layer film, an inner polymeric layer and a core layer of a lesser stainless steel material disposed between the outer polymeric layer film and the inner polymeric layer.

Corrosion resistant sheet metal jacketing

A method for making a collated fastener assembly includes arranging a plurality of fasteners in a row parallel to one another, in a plane, and spaced from one another, preheating the fasteners, applying a molten polymer material onto the fasteners and conveying the fasteners with the polymer into a mold cavity. The fasteners are maintained in the plane. The polymer is molded onto the fasteners and between adjacent fasteners to form a molding having a collar encircling a shank of each fastener and a connecting portion between adjacent fasteners. The molding maintains the space between the fasteners. A cooling stream is introduced onto the fasteners and the molding as the fasteners and the molding exit from the mold cavity.

Method for making debris-free nail collation

A fastener assembly is configured for use in an associated fastener driving tool for driving a fastener from the assembly into an associated substrate. The assembly includes a row of fasteners, each having a shank, arranged substantially parallel to each other. A collation system is formed from a plastic material that is molded onto and adhered to the fasteners. The plastic material is molded to define a collar portion substantially encircling the fastener shank and a connecting portion extending between and connecting adjacent collar potions. The plastic material is formulated from an adhesive polymer. When the fastener is driven from the driving tool, the collar portion remains adhered to the fastener such that the collar portion penetrates the substrate with the fastener.

Debris-free plastic collating strip for nails

A fastener assembly is for use in an associated fastener driving tool. The assembly includes a row of fasteners arranged substantially parallel to each other. Each fastener has a shank and defines an axis. A collation system is formed from a plastic material that is molded onto and adhered to the fasteners. The plastic material defines a collar portion at least substantially encircling the fastener shank and a connecting portion extending between and connecting adjacent collar portions. The connecting portion includes a bridge and a rib. The bridge is a relatively thin, elongate element spanning adjacent collar portions and the rib is a relatively thick, short element that is disposed at about an upper portion of the bridge. When the fastener is driven from the driving tool, the collar portion remains adhered to the fastener such that the collar portion penetrates the substrate with the fastener. The connecting portion can include a weakened region for separating the connecting portion from the collar.

A fastener assembly for use in an associated fastener driving tool for driving a fastener from the assembly, in sequential order, into an associated substrate, includes a row of fasteners arranged substantially parallel to each other, each fastener having a shank and defining an axis and a collation system formed from a plastic material that is molded onto and adhered to the fasteners. The plastic material defines a collar portion at least substantially encircling the fastener shank and a connecting portion extending between and connecting adjacent collar portions. When the fastener is driven from the driving tool, the collar portion remains adhered to the fastener such that the collar portion penetrates the substrate with the fastener, and the connecting portion includes a preferentially weakened region to influence separation of the connecting portion from the collar at a desired location.

An apparatus for forming a plastic molded collated fastener assembly includes a conveyor for carrying a plurality of fasteners in a horizontal plane defining an upper surface and a lower surface, a preheater for preheating the plurality of nails and a plastic collation molding station. The molding station includes injection nozzles for applying molten plastic to the upper surface of the fasteners and to the lower surface of the fasteners. The station further includes forming wheels including a holding section to, in cooperation with the conveyor, secure the fasteners. The wheels include a forming section to mold the molten plastic to the fasteners to form a collation having a collar encircling the fasteners' shanks and a connecting portion extending between the collars. The apparatus includes at least one cooling spray nozzle to spray a cooling vapor onto the fasteners and collations and at least one cooling spray nozzle to spray a cooling vapor onto the forming wheels. An air chiller further cools the collations.

Apparatus for making debris-free nail collation

A method for making a collated fastener assembly includes the steps of arranging a plurality of fasteners each having a head and a tip, in a row parallel to one another, the fasteners being arranged in a plane. The plurality of fasteners are preheated to elevate the temperature of the fasteners and a molten polymer material is applied onto the preheated plurality of fasteners. The fasteners, maintained in the plane, are conveyed with the molten polymer thereon between a pair of forming wheels. The molten polymer material is molded onto the preheated fasteners and between adjacent fasteners to form a plastic molding having a collar encircling a shank of each fastener and a connecting portion between adjacent fasteners. A cooling vapor is sprayed onto the fasteners and the plastic molding as the fasteners and the plastic molding exit from between the molding wheels. A gaseous cooling stream is forced over the fasteners and the plastic molding to cool the strip to form the fastener assembly.

Method of making debris-free plastic collating strip for nails

A method for powder coating articles includes the steps of preheating the article to a preheating temperature, coating the article with a polymeric powder coating having a cross-linking temperature that is above the preheating temperature and curing the article having the powder coating applied thereto at a curing temperature. The curing temperature is between the powder coating cross-linking temperature and the melting point temperature of the articles. A system for carrying out the coating method is disclosed as is an article made by the method.
