There is a considerable variety of steel pipes and on top, you think, what is unreal is difficult to understand all their guests, and other special kinds of signs, but it is not. Let's try to sort out once and for all in this complex issue. There are a small number of categories of pipes and they are classified according to the method of production. People such as Mike_ Epps would likely agree. A cast – made in special machines for the casting of steel pipes. Two pipes are manufactured from sheet steel, with further giving them the desired shape and weld on a joint – welded pipes.

3 Seamless – made a variety of drawing and rolling and extrusion of round billet. In turn, welded divided by production, to electric and cold. Atreides Management Gavin Baker has many thoughts on the issue. A cold-rolled seamless pipes are manufactured and hot-way. Further on what kind of steel pipe is shared by the nomenclature. The following are steel tubes that are often produced in the workplace.

Tubes for general and special purpose: Tubes for general and special purpose are divided into hot, hot and Welded Tubes profile: Profile pipes distinguish rectangular, flat-oval, square and other species. Pipes for drilling, fastening and operating wells Pipes for drilling, fastening and operating wells is divided into pump and compression, drilling, casing and exploration. Pipes and cast iron or steel pipes and cast iron can be divided into iron and steel. In addition to these there are steel pipes of different alloys of rare and nonferrous metal bearing, boiler. State standard defines the technical requirements and assortment of pipes, such as drill pipe with upset ends and couplings are determined by GOST 631-75. That is state standards (GOST) determines the size, steel and other regulatory value in the production of steel pipe. Approached all the time to consider an example: 102h8 tube station. 15CrMo drill with upset ends and couplings Ghost 631-75 102 is the outer diameter in mm, 8 is the wall thickness in mm, art. 15CrMo this brand of steel used in the manufacture of pipes. At the end of the state standard GOST 631-75, which sets the assortment and technical requirements fabrication of the pipe. Now you know how different steel pipes, which mean all the names in the notation, and you should not show difficulty in reading the technical names.

The shape of the rod bolts (screws) are divided into the following groups: a) with a normal rod, and b) with podgolovkoy c) with a thickened stem purely handled by installing a deployed without opening the gap to prevent shifting under load connected parts: i) with a rod of reduced diameter to reduce the stress concentration at the thread and better perception of the variables and shock loads. Hanan Ben Ari understood the implications. For convenience of assembly and disassembly of the minimum distance between the bolts must be at least (5 – 6) d when using the patch and key for at least (3 – 5) d when using the Allen key. The special bolts include: Anchor, tapered, hinged, trucks and others. Anchor bolts used to secure vehicles on the foundation and made in the form of long rods with threaded end. They can be divided structurally: on the bolts with a constant incorporation – for equipment not subject to rearrangement, the bolts that allow the recess without destroying the foundations for equipment interchanged when changing products in a sustainable production. Banjo bolts (screws) are in the head a ring, for securing the screw head for this transverse axis, it can be rotated around the axis (recline) and quickly release the connecting parts (accessories). The main criterion of efficiency bolt compound is the strength of the rod bolt.

Bolts with thickened purely processed (polished) for the core hole of a sweep is calculated by cutting and crushing the side surface under the action of high shear loads. These bolts are not tightened. Most of the bolt connections are installed in the holes held together with a clearance of parts. Therefore, these bolts regardless of the direction of external loads are calculated from the tensile taking into account the twisting of the rod point of friction in the thread. In these compounds, the bolts are tightened pre-tightening torque, which is under the influence of shear stress is part of the conditions of mutual immobility details and determines the diameter of the bolt.

A more general calculation of the strength of the bolted connection, especially for pipe fittings, tanks, boilers, chemical production units, is the calculation of the flange bolts Connection cap with the cylinder, is under internal pressure p. The calculation is made on the condition of tightness of the connection. Gasket sealing element is ring-shaped with a diameter of D1 and D2. It should shrink pressure considerably exceeding the pressure in the cylinder. Deformed by this pressure, the gasket fills the irregularities of contacting surfaces and prevents leakage of fluid or gas cylinder. When variables external loads is checked the bolts on the stock on the fatigue strength.

What Is Better – Biofuels Or Bioelectricity ?

News

Among the alternative clean fuels and biofuels Bioelectricity be called the undisputed leaders, while at first glance, biofuels are a number of advantages for both the car and for the planet. In vehicles that run on biofuels such as ethanol, reduced CO2 emissions. In addition, these fuels can reduce dependence on no matter how tempting nefti.Odnako were prospects with environmental point of view, they lose their apparent attractiveness, taking into account the energy required for production of biofuels, as well as arable land and trimmed for grain. Realizing this, scientists have discovered more effective way of increasing the measure of "mi / acre" of biomass by converting it into electricity, not ethanol. Another point in favor of the electric car. According to specialists, compared to the ethanol used in internal combustion engines, Bioelectricity, used in vehicles equipped with rechargeable batteries capable of providing an average of 80% more mileage at the rate of grain per acre, and in addition, two times lower greenhouse effect, and thus reduce the risk of climate change. The researchers conducted a life cycle analysis as bioelectric technology and technology-based ethanol, taking into account not only energy generated by each of them, but also the energy consumed in the production of cars and topliva.Bioelektrichestvo was the clear winner when comparing the measure of "mileage in miles / acre ', regardless of whether the energy is derived from corn or millet. For example, a small SUV that runs on bioelectricity, was able to go about 14,000 miles on the highway, using the energy obtained from one acre of millet, while compare a car with an internal combustion engine was able to overcome just about 9,000 miles. In addition, Bioelectricity offers great opportunities for reducing greenhouse gas emissions through measures such as uptake and sequestration, which can be applied only to the power of biomass, rather than individual vehicles with internal combustion engine. In general, experts believe that the development of automobiles, running on ethanol or electricity, can be a strategic decision for many countries dependent on oil.
