A restraint system for use in securing temporary flow lines that include multiple pipe sections, each pair of pipe sections connected together with a fitting or coupling such as a hammer joint coupling. The system includes multiple pluralities of endless loop slings connected end to end with a cow hitch or girth hitch knot. Disconnectable fittings (e.g., shackles) are placed every three or more slings so that easy disassembly is afforded in case of leakage or other failure. In one embodiment, a waterproof sleeve is an outer layer that surrounds or encapsulates an inner layer so that the inner layer remains dry and thus will not freeze.

A system of visual and non-visual marks for pipes and couplings which allows users to group the pipes and couplings by type, size, end configurations and composition with a series of symbols, including colors, shapes, swirls, patterns. The symbols are applied to the pipes and couplings by printing, etching, painting, applying stickers, and or molding. The non-visual mark utilize the magnetic and radio reflective nature of the marks to allow remote identification of the plumbing pipes and couplings after being buried.

A restraint net is provided for use in restraining a tight grouping of flowline elements where restraint lines are unusable. The restraint net includes a net body woven of one or more restraining ropes; and a net perimeter comprising one or more restraining ropes, surrounding the net body. The restraint net is configured to cover the tight grouping of flowline elements and being of sufficient tensile strength to restraint movement of the flowline elements in case of a failure or separation of the flowline elements in the tight grouping. A method is also provided of restraining a tight grouping of flowline elements where restraint lines are unusable. The method includes: providing the restraint net as described above; coupling a first point of the net perimeter to any one or more of an anchoring device, an adjacent restraint net or an adjacent restraint line; extending the net body over the tight grouping of flowline elements; and securing one or more further points of the net perimeter to one or more further anchoring devices, one or more further restraint nets, or one or more further adjacent restraint lines. Upon a failure or separation of the flowline elements, the restraining net restrains movement of the flowline elements.

A system for transporting corrosive or erosive fluids having a conduit or flow equipment with a flow bore, comprising; a flexible pipe, an adapter, an end connector, a clamp connector, insert(s), and a metal spacer. Insert(s) comprise an erosion resistant coating disposed around the internal structure that is a spring or helical structure. The insert(s) is/are disposed inside the flow bore and provide erosion and/or corrosion resistance.

Provided are an installation method and an installation device for a fluid control device capable of improving controllability of a fluid in a pipe by improving positional accuracy of a valve body inserted into a hole formed in a fluid pipe in a housing and decreasing the size, weight, and cost of construction equipment such as an operation valve device or an installation device of a fluid control valve.
