Cold urticaria is an allergic condition that affects the skin. Symptoms usually start in early adulthood. The most common symptom is a red, itchy rash that appears on the skin when it is exposed to the cold (e.g. cold weather or cold water). This reaction usually occurs within 5-10 minutes after exposure and can last for 1-2 hours.

Abstract: In the cold pilger rolling process, the pipe ingots are rolled out by means of a fixed conical mandrel and two rollers arranged in a roller assembly. The outer diameter and wall thickness of the pipe ingots are reduced by the forward and backwards movement of the roller assembly within the cold rolling machine.
During the past 10 years, many tube manufacturers have experienced work-related problems that have affected pilger machine operations and maintenance. Two pervasive problems are maintenance personnel changes and economic difficulties. Maintenance personnel changes involve job title and duty changes, retirements, and downsizing.
Cold pilgering is a longitudinal cold-rolling process that reduces the diameter and wall thickness of metal tube in one process step. Depending on the material, the cold pilger process achieves cross-section reductions of more than 90 percent in a single working cycle. Figure 1. The cold pilgering process relies on four main actions: The tube ...
Hypothermia is what happens when your body temperature gets very low. For an older person, a body temperature of 95°F or lower can cause many health problems, such as a heart attack, kidney problems, liver damage, or worse. Being outside in the cold, or even being in a very cold house, can lead to hypothermia. Try to stay away from cold places ...

Cold pilgering is a rolling process for metal tubes that reduces diameters and wall thicknesses. The Process. Located inside the tube is a stationary mandrel (1) which tapers in the rolling direction. This is attached to a long mandrel bar (2) which is secured in, and rotated by, a thrust block. Two dies (3) "form" the tubular stock in the same way that a rolling pin rolls out pastry.

present participle of pilger··A cold-rolling process used in the shaping of metal tube and pipe. It involves two circular dies, with an uneven u-shape along the circumferential axis, being brought into contact with a large pipe. The dies are rolled backwards and forwards to apply pressure all around the pipe, to reduce its diameter to the desired size[1].
Cold pilger mill machines perform work on preexisting tubes produced by means of cast, welding or extrusion. Pilgered tube metal alloys include aluminum, copper, gold, silver, stainless steels, titanium, zirconium and a host of many other special materials that are derived from various metal alloys.
The cold is the most common illness known, bringing the sneezing, scratchy throat and runny nose that we're all familiar with. People in the United States have an estimated 1 billion colds each year. More than 200 different viruses are known to cause the symptoms of the common cold. An estimated 30-35% of all adult colds are caused by rhinoviruses.
