Design and selection of check solutions from Val-Matic Valve & Manufacturing Corp

system design. With this knowledge, engineers can better select check valves and understand some of the pitfalls common to valve selection. Val-Matic Valve & Manufacturing Corp – USA valves@valmatic.com www.valmatic.com

Engineering parameters associated with check valve selection, such as flow characteristics, are discussed, along with headloss, reliability and costs. The combined characteristics of the pumps, check valves, air valves, control valves and surge equipment should be considered for successful pumping

Val-Matic’s redesigned white paper ‘Design and Selection of Check Valves’ aims to show which check valve is the best option. The white paper helps users understand basic valve principles and the functions of various types of check valves used in pumping systems.

Advanced seamless tube plant ordered Jiangsu ChangBao Precision Steel Tube Co, Ltd, based in Jiangsu Province, China, has awarded SMS group a contract to supply a new PQF ® (premium quality finishing) seamless tube plant and related automation. are used in oil and gas production (OCTG tubes) and must satisfy very high quality and tolerance requirements in accordance with API standards.

efficiency and flexibility of the mill. The order also includes the full automation of the machinery and plant sections, as well as laser technology for measuring the wall thicknesses downstream of the PQF and the stretch reducing mill (SRM). The CaliView ® measuring system developed by SMS group allows for fast in-line calibration of all rolling mills, ensuring the alignment of the mill line over a period of time. A networked, CNC-based groove dressing machine (KR) for high- precision machining of the SRM stands will also be supplied. The use of Lasus ® technology means the otherwise commonly applied radioactive isotope measuring technique can be replaced by a safe laser technology, which is environmentally friendly to operate and ensures monitor control with the PQF-SecControl-Technology as well as front and tail end sharpening in real time with the FTS system. Yield losses are minimised using the latest modules in the Cartaneo technology system. The functions CEC (crop end control, for reducing thick ends), WTCA (wall thickness control, average), and WTCL (wall thickness control, local) have been improved by self-learning algorithms (artificial intelligence, or AI). The new seamless tube plant is scheduled to be commissioned in the first quarter of 2020. SMS group GmbH – Germany communications@sms-group.com www.sms-group.com

With the BCO-type PQF plant (bilateral change-over), the stands are changed at both sides of the mill. The compact, easily accessible construction enhances the user-friendliness of the plant. The drive is simpler in design and is easier to service. In addition, the hydraulic capsules (hydraulic adjustment) are positively connected to themill frame. This ensures that the rolling forces are distributed symmetrically over the mill, resulting in a further improvement in wall thickness variations. This increases both the

Highlights of the scope of supply include various performance modules and a KR I 35/45 CNC groove dressing machine. The highly automated plant will enable ChangBao to meet growing demand for precise, high-strength tubes in its local market. The PQF ordered will be used to produce tubes within a diameter range of up to 6 5 / 8 " and wall thicknesses of between 4 and 20mm. Its annual capacity is 300,000 tons of tubes. The products
