Power station welding gate valve product features and implementation of standards

There are two standard forms of welding gate valve, one is to follow the introduction of ANSIB16.34 and JISL1E101 standards, the other is based on JB3595 standard GB. It follows the same temperature-pressure rating and there is some sort of interchangeability in some pipelines. The central part of the welding gate valve is self-tight with no valve cover pressure and has good sealing performance under high temperature and high pressure conditions. Self-sealing ring has two kinds of materials, one is low-carbon steel, the other is flexible graphite 316 wire (mesh). Welding surface of the top welding base carbide, the pure metal layer after processing ≥ 3mm, with wear resistance, high temperature, corrosion resistance, abrasion, long service life. Branch pipe at both ends of the welded structure, welding bevel according to the standard or user requirements. Power station welding gate valve for thermal power plants, petrochemicals, metallurgy and other high temperature and pressure water, metallurgy and other high temperature and pressure water, steam, oil, superheated steam pipe.

Portable Recycled Hammock

There are currently a wide variety of hammocks available. There are hammocks that are designed specifically for
backpacking and include mosquito netting along with pockets for nighttime storage. There are hammocks made
out of thin and lightweight material which makes them ideal for taking on day trips. Other hammocks include
self-standing metal or wood structures that support the hammock. Given that hammocks are commonly similar
lengths to accommodate for an average adult's height, most hammock stands are universal in design, typically
featuring a spreader bar that runs along the ground, feet for stability at each end, and a diagonal arm at each
end to provide two hanging points. Although they are usually bought premade, it is also possible to make your
own hammock.

For non-spreader-bar styles, the way in which they are hung is critical for comfort. Generally, a higher attachment
point is preferred as well as a sufficient length between points, though these two dimensions can be adjusted to
compensate for a lack in one or the other. The optimal angle of the attaching lines to the post/wall/tree is usually
about 30 degrees. Hammocks can be attached to the anchor points using a variety of suspension systems,
including ropes and webbing straps.
