2022 -- With the enhancement of our R·D capability and industry influence, we participated in the drafting and formulation of national standards and industry specifications respectively, including GB/T18944.2-2022 Specification for flexible porous polymer materials Sponge and foam rubber products Part 2; HG/T 2490 Specification for steel wire or fabric reinforced rubber hoses and hose assemblies for dredging; Rubber hose, oil suction and discharge, offshore mooring GB/T10541. The company's R&D capability has risen to new heights.

2021 - The company upgraded its laboratory equipment with the addition of flange lug testers, flange gluing machines, film cutting machines and pipe bending test equipment. The company regained ISO 14001 environmental management system certification, ISO 9001 management system certification by DNV and ISO 45001 occupational health and safety management system certification.

2020 - The oil hose business is in full bloom, with a partnership with Petrobras and steady growth in dredging hoses, marine hoses and mining hoses, with a total annual production volume of over 1,200 hoses and an annual production value of over US$20 million.

2019 -- Our company went to the Netherlands to attend the exhibition European 2019, where we showed various sizes of rubber self-floating hoses on site. We negotiated with many dredging companies on site and enhanced our reputation in the international market.

2019 -- Our company went to Brazil to attend the OTC and started negotiations with the engineers of Petrobras on site and reached a preliminary cooperation intention.

2019 -- Our company went to the United States for the first time to participate in the OTC exhibition and exhibited two oil transfer hoses on site, which caused a shock to the industry. This is the first time that a Chinese company with double carcass oil transfer hose production capacity exhibited at an international exhibition. Several overseas users invited us to participate in project bidding and hoped to go to China for a site visit to our company as soon as possible.

2019 -- Our company developed a new type of deep-sea mining hose for use under 1700m, which was tested by the deep-sea laboratory of Dalian University of Technology and achieved good feedback, filling the gap in this area in China.

2019 -- In response to the demand for large diameter and ultra-high pressure dredgers, we were commissioned by Boskalis Netherlands and Dutch Dredging Components BV to jointly develop a new type of large diameter dredging hose reinforced by a mixture of steel cord fabric and aramid cord fabric. After more than 10 prototype hoses were manufactured and tested, the overall performance of the final product met the customer's requirements. Over 200 of these types of products have been successfully delivered to date.

2018 -- After independent research and development, the 12" double carcass submarine hose and 24" double carcass floating hose based on the GMPHOM2009 standard were successfully piloted. The product design, raw material selection, semi-finished product testing, fatigue test and final burst test all met the requirements of the GMPHOM2009 standard and were awarded a certificate of conformity by the French classification society (BV).

2018 -- As the company continues to develop and grow, a company with over 30 years of experience in dredging hose manufacturing was acquired to bridge the gap in terms of production capacity. After the integration of its resources, the company's R&D team, production equipment, inspection equipment, technical reserves and intellectual property rights have been improved. After relocation and renovation, the plant area has reached 30,000 square metres, the number of employees exceeds 100 and the annual output value exceeds US$10 million.

2016 - A dozen rubber engineers with a dream, walked out of state-owned enterprises, left their comfortable environment and went on to start their own business. At the beginning of the company's establishment, the founders set the direction of development as special rubber rubber products for marine engineering. The main products include rubber dredging hoses and rubber oil hoses.
