Guangdong random decorative welding stainless steel pipes failed Jinliang Chen
From;    Author:
Quality Supervision Bureau of Guangdong Province, recently informed the decorative welding stainless steel pipe products, supervision and checking of results, product quality and a pass rate of 80.8% within the 15 batches of products of poor quality has been exposed, involving stroke Chao, Rui Feng, source Hongfu, Xin Hua Long Brands. The sample of Guangzhou, Foshan, Jiangmen, Maoming, Zhaoqing, Dongguan, Shenzhen, Jieyang, Chaozhou, Shantou and other 80 enterprises in 10 regions of decorative stainless steel pipe products produced 99 batches, the test, qualified 58 batches, Product sampling batch pass rate of 58.6%, excluding only the identification of 22 batches of substandard products within acceptable quality rate was 80.8%. Year 2009, the special supervision and checking of batches of provincial pass rate of 54%, improved 4.6 percentage points. Substandard Grid project is mainly signs, chemical composition, thickness, corrosion resistance. Chemical composition of 16 batches of substandard projects, such as excessive Mn, chromium, nickel content of less than. Manganese content exceeded the process will affect the product, whereas chromium and nickel content of less than, it will reduce the corrosion resistance of stainless steel, Yan Weight of the product appearance and performance. Companies failed mainly due to the lack of necessary testing equipment monitoring the quality of purchased sheet there is also some enterprises to reduce costs, deliberately chosen for students with low grades of steel Production situation. Not meet the standard requirements of thickness and 5 batches. Thin stainless steel tube wall thickness can cause structural strength is not enough, after stress deformation, affect product safety. Failed mainly due to manufacturing enterprises in pursuit of economic efficiency, Vendors to meet the requirements, deliberately thin charge will be thick, small scale large. Corrosion resistance of 3 batches failed. Corrosion-resistant for outdoor use substandard products are susceptible to corrosion, the use of stainless steel performance and security. Quality supervision department, said the sampling results indicate that although the decorative stainless steel tube, Guangdong Province rapid development of the industry, but still mainly small and medium-scale enterprises, the overall quality level is not high. Optional decorative sense welded stainless steel pipes Consumers to buy decorative welding stainless steel pipe products: 1, to view the appearance of product quality, and whether there is corrosion, cracks and lack of material, etc.; 2, to carefully see whether the goods have product certification, dealers are able to provide third-party product testing reports issued; 3, to view the product logo is clear, correct, complete, such as decorative welding stainless steel pipe products shall be marked with manufacturers name, address, material grades, sizes, etc., in particular, observe the clear material grades, not Material with a large price difference between grades, the purchase of 304 stainless steel, the best sample to detect the interception unit testing; 4, coastal users, the best choice for good corrosion resistance of 304 stainless steel tube; 5, the proposed consumer preference is strong in technology, quality and stability of large-scale production of large corporate brand products, as well as direct sales to businesses or to purchase formal sales points; 6, routine maintenance cleaning, do not allow the use of acid or alkaline cleaning solution, the application of water to clean.
