Putian welded pipe equipment, strong support for the three subjects of stainless steel machinery 


 "Chenzhou three subjects Steel Co., Ltd." was established in 1993, is dedicated to high-end stainless steel tube equipment developed high-tech enterprise, the company has a number of self-developed patents, also passed the ISO9001 quality management system certification and the company with independent import and export rights. "Respectively" product because of its superior performance, high-quality cost-effective, chasing in the industry, far ahead, a number of large syndicated corporate and powerful state-owned enterprises are our long-term customers, and because the product has a high good quality so that the "three subjects' well-known overseas products, products sold: Malaysia, Taiwan, Vietnam, Bangladesh, Kenya, Russia and other countries with foreign high-end products competing against. With the continuous development of the company in 2009, "Steel Co., Chenzhou three subjects" more phase of Foshan location and mature market in Foshan Nanhai Luo village set up a "three subjects the company Foshan factory" allow the company to further influence to expand. 
 "Respectively" product groups according to the different needs of the customer segments targeted a "stainless steel decorative tube machine" and "stainless steel industrial tube machine", and then combined the customer's actual situation and then subdivided from the two series a "high-end machine", "precision machine", "ordinary machines" three grades to meet the different needs of customers. "Respectively" equipment specifications vary, pipe from ￠ 6 ~ ￠ 325, thickness from 0.2mm ~ 8mm. Mold, polishing machine, embossing machine, the leveling machine, annealing equipment and other equipment the company readily available to provide customers with full service head to the tail of the sound, so that customer does not have to worry about. 
 We always adhere to "focus on quality, creating value for customers" business philosophy! Warmly welcome colleagues sincere cooperation and common development! 
 The following is the promotion of the article, has nothing to do with the company 


 To distinguish between the quenching cracks or grinding cracks. Pollutants are not attached to the crack is easier, meaning quenching cracks and different forms of grinding cracks. Not found for the quenching and after the discovery of cracks in the grinding. At this point note that the crack patterns, especially the direction of crack development, grinding cracks are perpendicular to the grinding direction 

 The quenching cracks. Deeper than normal, relatively large, was parallel to the line shape (Figure 1) or showed a crack-like shells. Very shallow depth of grinding cracks. Nothing to do with the grinding direction, mostly straight knife-like cracking. Second, pay attention to the site of the crack occurred. Sharp convex corner, the edge of the hole, engraved office, 

 Crack occurred in these areas are mostly quench cracks. Third, playing Seal Department and the appearance of defects caused by machining and other parts. By observing the parts of the split section to distinguish between quenching cracks or forging cracks before hardening, or other conditions caused by the cracks. If the crack cross-section of red or dark red or light red (created when water quenched 

 If the crack cross-section of dark brown, rust into the water) can be determined to quench cracks. Aerobic skin appear even, it is not a quenching crack, Department prior to quenching cracks, forging or rolling parts through the formation of cracks when these cracks will be expanded due to quenching. Basically due to quenching cracks below the M point
