Brief Introduction:      

    

Datong Donghua Mine Machine Co., Ltd. is the first professional cooperation of producing, developing, and researching concrete conveyer pumps and parts in China , and gains International Standard Certificate of ISO9001,2000.

 

Datong Donghua Mine Machine Co., Ltd. has advanced production equipment and well-equipped detecting instrument, owns professional technicians who apply theirself to research and develop the new products. The professional technicians adopt Germanic technology, research and develop “DONGCHANG” brand concrete conveyer products (ardening layer, twin wall, reducers, and elbows), which are suitable to Chinese concrete conveyer industry; obtain invention patent (patent NO.ZL03111908.5) from State Intellectual Property Office of The P.R.C; win the honor of “Famous Brand of Export Product in China”, “Well-known Brand in China”, “The Standard AA in Good Quality and Faith” etc; are under the requirements of environmental protection, adopt advanced and substituted products, and are up to the international standard in the terms of the technology and quality.

 

  “DONGCHANG” brand concrete conveyer straight pipes have the advantage of highly resistant abrasion, are the first generation hardening layer pipes; pick up special alloy steel, adopt imported facility and the technology of high frequency heat treatment, so as to make the inner wall of pipes become high intension, hardening layer (55-62 HRC), toughness layer (1.8mm) and highly resistant plasticity and transformative ability in their outer wall, consequently, “DONGCHANG” brand concrete conveyer products achieve the best combination of high intensity, hardening layer, and good toughness, so that concrete conveyer pipes can endure more impact and abrasion from the aggregate, such as screes, gravels and granite; improve the resistant abrasion ability and the work life of the concrete conveyer pipes; and are as  4-5 times as normal concrete conveyer pipes!

 

  “DONGCHANG” brand concrete conveyer twin wall pipes are the first in China; have the advantage of safety, longer work life, energy saving, continuum, low maintenance and good benefit; are the second generation of advanced products developed on the basis of hardening layer pipes; are the most advanced technology in the world until now; adopt special facility and supersonic frequency and heat treatment in the inner wall; are up to HRC 60-65 and thickness 2.5mm in the resistant abrasion wall; thoroughly resolve the problem that hardening layer pipes happen to rupture and blow out under the situation of the thickened hardening layer and twin wall has different layer and is easy to be stricken , shaken and broken after the shock, so, after special treatment, they can prolong their work life, their concrete conveyer quantity can be up to 50000-80000 3 averagely. “DONGCHANG” brand abrasive twin wall products win the clients’ praise after they entered into the domestic and international market.

 

    The products are widely used in the concrete pumps conveyer pipes, trailer-mounted concrete pumps’ pipes, concrete placing boom pipes, and concrete batching plant pipes etc. Datong Donghua Mine Machine Co., Ltd specialize in producing concrete conveyer pump spare parts used in FOTON, SANY, ZOOMLION, XCMG, HAINUO, JIANJI, XINGMA, HONGDELI, PUTZMEISTER, JUNJIN, and SCHWING etc; at same time, provide kinds of hardening layer, twin wall, reducers, elbows, abnormity pipes, different coupling, eye-board, cutting ring, rubber gasket, sponge ball, elbows made by and cast steel or manganese steel etc.
