Hidden troubles of wind turbine quality (4)

Prob1em III: Ouality of tower flange do not experJence rigorOus test of time. Over the last two year, many flange manufacturing plants jumped out and sprang up all over the pIace. Many enterprises do not have the process management, vertical axis wind turbine inspectlon and test capabilities of production, coupled with the insufficiency of product acceptance of tower flange usersl it does not show the reaI quality issues of product. In addition, generator set operation has not yet reached the high-incidence season of machinery equipment failures within over two years, greater problems and challenges may still lay ahead. Tower flanges currently in use have occurred several major quality problems, such as wind turbine flanges supplied by a foreign wind turbine flange manufacturer occurred low--temperature impact performance probIems, caused a large number of return and had to bear the huge compensation. For the settlement of hidden qua]ity troubles brought by vicious competition in the market of wind turbnie flange, I believe, fIrst to accel-erate the formulation and promulgation of national standards of " Wind Power Generator Set Flange" by industrial association, and regu1ate processing and manufacturing, inspection rules and testing methodsI second, raise market access threshold and proposes hjgher requirements to equipment capacity, inspection level and qualif1cation of wind turbine flange manufacturers and supp1iers at the tender, and assess whether the suppliers have sufficient resource Supporting capacity, third, tower flange users should understand the reasonab1e market cost price in advance and do not accept the Iowest quoted price at the tender and tender evaluation in order to make every effort to create a platform for fair competition not only depending on quoted price but aIso on their demonstrated potential to tower flange manufacturers and suppIiers, fourth, tower flange users should strengthen acceptance standards through occaslonal sampIing and on -site random sampIing to urge the manufacturers to improve product quality, fifth, take corresponding supplier management approach to ensure stabIe and healthy development of supply chain, establish strategic cooperative relations with Suppliers, avoid vlcious competition and take favorabIe costs contro1 capability as weI1 as stable and re1iable product quality of tower flange manufactures and Suppliers as the cornerstone of biIateral cooperation. In light of the hidden quality troubles of tower flanges currently appear in the industry due to vicious competition, as a member in the industry, l propose the said personal views with the purpose of exchanging view with you and Joint discussion. I hope it could heIp to solve the problem of cut--throat competition current1y existing in the industry and make contribution of heaIth and rapid deveIopment of the industry.
