Yanshan County Bo Yan Pipe Co., Ltd., located in the pipeline equipment manufacturing base in China - Hebei Yanshan industrial area south of Cangzhou City, is a development, development, production of steel pipe products manufacturing enterprises. Our company has always insisted: quality-oriented high efficiency; high credibility to German-based; high-tech people-oriented; quality in law-oriented management philosophy to the Constitution, to produce high-quality products back to customers. Enterprises adhere to the quality of survival, carbon steel pipe cap model, relying on services and policy development. Quality First, the user first, is our aim. Dish cap of r at avoiding splicing, will thinned, high stress. When welding seam direction requires only allowed radial and circumferential. After the large cap may cancel this requirement. Stitching distance should request greater than 3δ, and not less than 100mm (HAZ is a high stress area, and in the chemical composition of the area will be burning. So to avoid high stress area, the region and the thickness of the relevant According to experience, the stress decay length greater than 3δ, carbon steel pipe cap, and not less than 100mm). But the cooling equipment is difficult to meet this requirement, carbon steel pipe cap head, has its particularity. Head of NDT including what us, elliptical head is not very strange, in any large production sites would prefer to use head device, for their actual usage, to determine the type of use of Head. Inspection and non-destructive testing head is part of the process is also one of the standard test, so for this part, we learn to be good, a good grasp of it, so as to be able to use it in the manufacture of head, so as to provide some guidelines for our inspection. First, the general shape and size of the head, the minimum thickness and forming non-destructive testing, etc., should be in accordance with regulations and standards, its inspection and reinspection to ensure the overall quality of the head; the head after cutting, to be measured roundness tolerance; Second, generally the difference between the maximum and minimum value, the value should be less than 25mm. In any two-diameter position on the end face of the head should be put straightedge or taut wire, for measurement of the total depth, generally can not exceed a predetermined value; Third, using the gap model, to check form tolerances inner surface of the head , note detection model be perpendicular to the test surface, otherwise the result may not be accurate. Head products fully comply with those requirements, Hebei steel pipe cap, quality products that can be sold to the market, but for those problems head products, the need for further testing and improving sales are allowed. Carbon steel pipe cap head, Bo Yan Pipe, carbon steel pipe cap by Bo Yan Pipe Co., Ltd. Yanshan County. Yanshan County Bo Yan Pipe Co., Ltd. (www.czbygy.com) quality of service and products, continue to receive the recognition and trust of new and old customers and the industry.
