Agar agar, carrageenan, and other vegetable gums are vegetarian substitutes used in some products. For marshmallows and jels made without animal gelatin, check out online retailers, such as the Vegetarian Site.com, Pangea, the Mail Order Catalog, Vegan Essentials, and Ethical Planet, or elsewhere.osher gelatin is derived from kosher slaughtered and processed bovine sources or from kosher species of fish. Gelatin derived from fish is permitted in yogurt or other dairy foods according to most opinions.. Star-K also told us their position on the use of gelatin (a meat product) in yogurt (a dairy product).
SPIRAL WELD PIPE. Spiral Weld Pipe, as the name implies, is a steel pipe which has a seam running its entire length in a spiral form. In the past, due to the method of manufacture, Spiral Welded pipe was relegated to low pressure and structural applications.ontinuous Weld pipe is available in 21 foot uniform lengths. single random lengths from 16 foot to 22 foot and double random lengths from 38 foot to 42 foot. Continuous Weld pipe in sizes NPS 1V2 and smaller are normally put in standard bundles as indicated in the following chart.
It is often desirable to combine the discharges from safety relief valves into common pipe headers. The common headers are piped to a safe location, with provision for collecting liquid relief and treating vapor discharge. VentManifold is an Excel spreadsheet template that calculates the backpressure that develops when simultaneous vents discharge into a common header. This is important because relief valves are designed to operate within specified back pressure limits. This page discusses the design of relief valve discharge manifolds. A relief valve discharge header takes the form of a tree. Each valve, vent, or rupture disc is piped to a branch; branches may combine into larger branches. Finally, the main trunk is reached, discharging to atmosphere (perhaps by way of a large knock-out drum or scrubber).
