Asphalt sampling valve

531 asphalt sampling valve Name: asphalt sampling valve, also known as: asphalt sampler, asphalt sampler Model: Z413-16C use - asphalt sampling valve body are made of high quality forged parts processing, usually used to obtain bitumen, oil pipe way valve or device to take a sample of the media, in accordance with the principle or the performance of the different sampling time can also be widely used in thermal power plants, chemical, oil refining, pharmaceuticals, paper, sugar, food, machinery and other work-controlled hydraulic piping systems. Operation - ★ sampling from bituminous asphalt storage pool storage pool should be heated, melted asphalt, bitumen by pipeline or pump flow to the asphalt sample after heating bath. Each pot-minute interval taking at least three samples, and then these samples were mixed well and then take a predetermined number as a sample, the sample may be tested separately. ★ after sampling from bituminous asphalt tanker transport ship to Hong Kong, should be separately sampled from each pitch warehouse, each bin taken from different parts of the three samples, mixed together, as a warehouse for asphalt samples for inspection. Sampling in unloading process, should be based on the amount of unloading roughly divided evenly spaced three times en route from unloading port or pipeline sampling port sampling, and then mixed as a sample for testing with. ★ sampling a bucket from the asphalt) can be confirmed when the same group of products, it can be a random sampling. If you can not confirm that the same group of products, should be in accordance with Table 1 or press the cube root of the total number of barrels of bitumen barrels randomly selected according to the number of barrels. 2) heating the asphalt barrel barrels of asphalt melts after all fluid parameters - Size: 3--15 temperature: -20 ℃ - + 440 ℃, -70 ℃ --240 ℃ Pressure: PN2.5-PN16 material: carbon steel, stainless steel
