Established in 2009, aohai anchor chain co., ltd. Specializes in the production of marine anchor chains and offshore mooring chains. The company is located in the jingjiang industrial zone (jiangsu province), which is near the yangtze river with extremely convenient transportation. With about 500 staff, including engineers, project technicians and administration personnel to largestly guarantee the highest quality with scientific design, efficient production and strictly control.
Aohai adopts advanced flash butt welding and the production is in accordance with iso1704, gb549, gb/t20848 and the standards of the leading classification societies worldwide. The main products are marine anchor chains and mooring chains with diameter from 22-166 mm. Our annual production capacity currently is around 100, 000 tons and expected to increase dramatically in the following further investments.
Manufacturing advantage:
-- more than 20 years experience in anchor chain production. With license approval :iso9001, oshms18001, iso14001, api and type approval by all iacs members.
-- advantage manufacturing facilities: advanced program-controlled chain production line; automatic heat treatment machine; automatic shot blasting machine.
-- quality control: material fatigue test on request; stress analysis on request; stress actual test on request. Magnetic power testing, ultrasonic testing, and fluorescent penetrant inspection.

Five-part nonlinear modification function of sensor, automatic operation of average flow, and easy for calibration.
Integrated cantilever structure, high strength, anti-shock and anti-resonance;
High accuracy (Liquid 0.75%, Gas/Steam 1%), Divide the signal flow and the noise flow, accurately measure the low flow;
Digital dynamic tracking filter technology, greatly improve the measuring stability;
Hart communication or Profibus is available. Analog and Pulse signal output, 4-20mA Output;
Advanced self-diagnosis function. Display changes of working conditions, like pipe vibration and abnormal flows, etc.;
Compact structure of converter, easy to install and use;
No moving parts in the stainless steel sensor, safety and long service life.
High accuracy. The symmetrical arrangement of the multi-hole ensures the flow profile to be steady and conditioned thus reducing the turbulence effect. Life time is 5-10 times longer than the traditional throttling devices;
Shorter straight pipe. In most cases, the length of straight pipe can be as short as 0.5D-2D;
Low Permanent Pressure Loss. Symmetrical structure decrease the formation of vortex flow and turbulence friction, saving the running cost;
Wide flow range. Range ratio can improve to 20:1 - 30:1 if appropriate parameter is selected;
Repeatability and Long-Term Stability. Balance the flow field, and improve the repeatability.
Outstanding quality: accuracy of ±0.075%;
Measuring Flow: liquids, gas, steam;
Measuring range(not drifting):0-100Pa2MPa;
Isolating diaphragm: 316L stainless steel, Hastelloy C, Ta, Gilded stainless steel 316L, EFP-coated stainless steel 316L;
Small, firm, light, easy to install;
Valve manifold, primary element and remote seals settings can be unified.
