|LONDON Henrik Lundqvist White Jersey , Sept. 14 (Xinhua) -- London's prestigious Royal College of Art has collaborated with Britain's Ministry of Defense (MOD) to design a 21st century combat uniform for the British military.
The future concept uniform went on show for the first time Thursday at the showpiece Defense and Security Equipment International exhibition in London.
The combat uniform is part of the MOD's plan to give high-quality, cutting-edge equipment to British soldiers.
Royal College of Art (RCA) researchers and designers worked on the clothing to ensure prototypes were fitted to the body, easy to run in and comfortable to wear.
Prototypes of the new clothing have already been assessed at the Specialist Weapons School in Warminster to help examine future uniform concepts.
Kit designed so far includes advanced combat clothing, with new materials like four-way stretch "phase-change material" and silent hook-and-loop pockets. The enhanced body armor is stronger Ryan McDonagh White Jersey , as well as having a new high-tech helmet with state-of-the- art, built-in communication systems.

OK, I know you want to grab the portable propane torch and fire up that frozen pipe in your crawl space. This is the most dangerous practice to solve this problem because an open flame in a tight space, coming in contact with wood, insulation paper Henrik Lundqvist Black Jersey , plastic piping & plastic wire coatings is a recipe for a disaster. Pipes and wires run through small holes in the framing and in vertical voids of the structure. The torch user can inadvertently send super-hot gases into these voids (condensing the gases which create a greater heating effect on the gases, remember our thermodynamics from above). Unbeknownst to the torch user, a fire is started in this void out of their view and will race up vertically in the void.
The prudent pipe unfreezer person resists the temptation to use the torch & confidently grabs an electric heat gun or hair blow dryer and patiently unfreezes the pipe. Be careful with these electric heat guns as they throw off substantial heat and if held close enough to wood framing members or other flammables can start a fire just like a torch. Keep a safe distance when operating these tools and refer to the operating manual for safe distance recommendations.
Another safe method is to create a sealed cavity or space around the frozen pipe and add a low level heat source to this cavity for gradual thawing of the pipe. For example, if you had a crawl space that had a frozen pipe & you could somehow create a cavity around the pipe with no wind infiltration (somewhat sealed) Ryan McDonagh Black Jersey , you could do something as simple as adding a relatively safe heat source (a lamp or drop light) to this cavity which would eventually heat up this small environment enough to safely & slowly thaw the pipe.
Another safe practice is to wrap the frozen pipe with an electric heat tracer. The heat tracer will gradually thaw the pipe. The heat tracer would often times need to be fed by an extension cord from a more remote power source (outlet)
What will happen if you just wait for the pipe to thaw naturally?
Hmmm, that’s the gambling man (or woman) approach. I like your moxie & I can appreciate gambling as an activity as it’s very exhilarating when you win, but when you lose…not so good, right? One thing to consider and understand is what occurs during the freezing & thawing process.
Water freezes Mika Zibanejad Womens Jersey , and if you remember what we all learned in grade school about the qualities of water you will recall that water expands when it changes from a liquid state to a solid state. That expansion of water within a contained environment (a pipe) can cause the pipe to split. This splitting or cracking of the pipe, or the pipe fitting, is the risk with a frozen pipe. Not every frozen pipe will result in a water leak but be aware that you probably won’t know if the pipe is leaking until the pipe thaws by, manually by heating it (heat gun) Mats Zuccarello Womens Jersey , or if the environment around the pipe is heated (naturally or artificially). The water in the pipes are pressurized so one can imagine that once the thawing reaches a certain point the water will begin to flow rapidly through any break in the pipe or fitting which will leave you minimal time to prevent an even larger water damage condition. A safe practice would be to depressurize the affected pipe by turning the appropriate valve off. Which valve to turn off is anyone’s guess as every situation is different. You could turn the water main off, which would be kind of a catch all safety measure as all domestic water pipes eventually get their pressure from the main water supply. However, the heating pipes have water within a contained separate system that will have boiler pressure separate from the wa.
