Tn 2001, Wuhan YongTai corrugated pipe Co., LTD in the original hydraulic valves, and on the basis of restructuring into a joint stock limited company, is a professional production of various kinds of metal bellows expansion joint, nonmetal expansion joint, corrugated metal hose, pipeline and spring a, hanger bearing etc series products manufacturing. The company covers an area of fifteen thousand square meters and a building area of ten thousand square meters. The number of existing staff about 200 persons engineering technicians about 50 persons, middle and senior professional titles about 20 persons. The company has professional production equipment, test equipment more than 110 sets of fixed assets, more than 1800. Is our country all kinds of expansion joint, metal hose, the main pipe production base of support.
I company in early 2002 passed the ISO9001:2000 quality system authentication, and then made the pressure pipeline section with expansion of special equipment manufacturing license. Also made products comply with GB/T12777-1999 "metal bellows expansion joint general technical conditions", GB/T14525-1993 "a corrugated metal hose general technical conditions" standard certificate. Many years later, provinces and cities "by the contract and keep our promise" unit and "quality product" title, get the AAA level credit enterprise, authentication. Become the Chinese mechanical engineering society pressure vessel branch, China petroleum and petrochemical equipment industrial association expansion joint branch organization member units.
With the development of production scale and expand, my company has a complete set of advanced production equipment, professional inspection equipment: including bellows hydraulic molding equipment 5; Different specifications and use of cutting machine, drum machine and Taiwan; Submerged arc welding machine, CO2 gas protect welding machine, thin wall argon arc welding longitudinal seam automatic welding machine, the argon arc welding machine, electric welding machine, cutting machine over 40 sets of); Air test, hydraulic test device (4), etc. In addition, and general mechanical equipment more than 20 sets.
In the long-term production process, my company through production practice, the pilot study, complementary with computer software design, including large amounts of data, and has accumulated rich experience in the production of various series, expand section of the science, advanced production process documents ", "the expansion joint process quality standards", "the corrugated metal hose process quality standards", "the corrugated metal pipe welding, inspection process rules and a series of process documents and standard, make the product production each working procedure, work in accord with a standard step, all of the controlled condition, ensure the stability of the products and the quality of the product.
At the same time, the company according to the metal bellows expansion joint general technical conditions "(GB/T12777-1999), and" the American expansion joints manufacturers association (EJMA standards), "and" the pressure vessel waveform expansion joint "(GB16749-1997) standards such as design, manufacture and acceptance. Using the advanced computer software, the bellows optimization design ensure the expansion joint, the main technical parameters, to the best matching, fully satisfy the customers use condition requirements.
At present, our company can normal series of the expansion joint production of 20 more forms: various forms of round metal expansion joint specifications, rectangular metal the inflation festival; All kinds of round and rectangular nonmetal expansion joint. In addition, still can produce various specifications of the stainless steel corrugated metal hose, various type specification puff pipe plane sliding, and various types, guide bracket of the spring, hangers, can according to customer needs, meet the operation condition of the user.
The company always adhere to the "with research and development, strives for the survival by the quality" the principle, in efforts to raise the company independent research and development and innovation ability at the same time, keep the design and manufacture of the products quality in work first. First of all, in the process of production, the key link configuration has the information ministry and high level personnel management, control, strictly according to ISO9001, 2000 quality management system procedures and standards, the control each working procedure quality products. Especially quality inspection system, enacted a series of measuring technology procedure, test procedures, from raw materials to the reinsertion products factory inspection each working procedure, all executive level 3 inspection system. In the process of production of special operations and the critical process, the strict records, check all, every city quality supervision and inspection bureau to sampling inspected, to ensure that the design and manufacture of the products quality.
Because of my company has good social image, good credit, the technical force is abundant, the production ability, product quality and cheap, serious, thoughtful after-sales service, the company each kind of product for a long time for the domestic numerous design institute, China engineering construction standardization association recommend, selection use; Product application covering almost all provinces, municipalities and autonomous regions, widely used in(1) the metallurgical industry in the steel, iron, heat, gas supply (vapor), hot and cold wind system; (2) of the power industry generating set, pulverized coal system, the steam piping network, hot and cold wind system; (3) the regeneration of the reaction of petrochemical industry, energy recovery, catalytic cracking unit of pipeline etc; (4) the city heating steam and hot water pipe network; (5) and coal mining, car, the fuel gas heat, smelting aluminum, food, machinery manufacturing, etc. And these exported to Iran, Sudan and other countries. The application of the product quality is reliable, the performance good, wins the general new old customers' praise and the high praise, and consolidating and expand market share.
At the same time, our company in the whole nation each big, the city, 20 more office set up in time, knowledge and understanding of the user's information and requirements, timely tracking products use, to provide users with the fastest, convenient service.
Our company general manager Yonghe Huang rate all my colleagues will as always, sincerely for the new and old customers with the high quality service, welcome the masses of customers to come and visit the guidance.
