Langfang Dingsheng Mechanical Equipment Co., Ltd. (THE DSH MECH.) was established in 1988, covering an area of 35000㎡, specialized in designing and manufacturing coating machine, like pipe coating machine(pipe internal &external coating equipment), reinforcing steel bar coating machine, concrete coating machine, construction machine part, etc.

With more than 20 years' experience, we passed CE&ISO certificate. Our pipeline anticorrosion equipments have been successfully put into use in oilfields, long distance oil and gas transportation pipeline engineering . We can design and manufacture various non-standard pipeline coating equipments according to customer's requirements. By referring to relevant standards at home and abroad, introducing advanced technology abroad, we realize complete sets of equipment system integration from single anticorrosion machinery parts.

We can conduct various structural anticorrosion projects with complete set of internal&external anticorrosion coating line. 3LPE coating line is used for coating of pipe external FBE, PE jacket and 3LPE (PP). Also, by introducing new technology from the world's leading pipeline coating industries, we can meet the requirements for 3PE, 2PE, FBE, 2FBE, 3PP and international standard like German DIN30670(PE), DIN30678(pp), Canadian Z245.20-98(FBE), Z245.21-98(PE), SY/T 0413-2002, Q/CNPC 38-2002(2FBE), etc.

Our pipe internal coating lines technologies have many advantages: larger capacity, higher standards and stronger reliability, specially suitable for internal pipe coating with big caliber. currently, our pipe coating operating lines play a major role in domestic key pipeline anticorrosion engineering construction. Our single anticorrosion line can up to 500-1500 km/yr, approaching or being the world's top level.

Our aim: improve the company's innovation ability, enhance the company's core competitiveness, develops the market, to serve on the customers better!
