Application Scenario
Established in 2003, Letone is an industry-recognized high-quality rubber hose manufacture and service company, which devotes to the production, R&D, and sale of rubber compounds, rubber hoses & fluid connectors and rubber-plastic seals. Thanks to its stable quality and good reputation in the market, Letone has won the"Top Ten Rubber Hose Enterprises in China" issued by the China Rubber Industry Association Rubber & Belt Branch for many consecutive years. On 15th Nov. 2021, Letone (Stock Code: 832225) is listed on the Beijing Stock Exchange.
Letone now has 46 high-speed steel wire braiders, 12 steel wire spiral production lines, 8 industrial hose production lines, 200 CNC lathes and 2 automatic rubber compound production lines service in-house. Meanwhile, Letone is capable to produce rubber compounds 15,000 tons per year, rubber seals and other rubber products 20 million pieces per year, and the annual production capacity of hydraulic hoses and industrial hoses has increased to 30 million meters.
As an experienced professional hose manufacturer, Letone has obtained the Safety Certificate of Approval for Mining Products, certificate of MSHA, API Type Approval (API 16C and API 7K), ABS Type Approval (Drilling Equipment and Flexible Wire Braided Rubber Hose Assembly), GOST certificate, Lloyd's Fire Test Certificate and meets the requirements of quality management systems such as ISO14001:2015, ISO9001:2015, API Q1, IATF 16949:2016, etc. Letone also holds the environment management system international certification issued by IMS (comply with ISO14001:2015 standard). The Letone Testing Center has obtained the Laboratory Accreditation Certificate issued by CNAS in 2016. There are more than 20 laboratories include impulse test laboratory, burst test laboratory, fire test laboratory, salt spray laboratory, etc. The testing report is identified as objectivity, accuracy and authority.
Application case of excavator hose in construction machinery
Widely used in various types of construction machinery such as excavators. It has the characteristics of long life (5 years weather resistance, 2 years warranty), high pressure (25% higher than SAE/DIN standard), pulse resistance, low bending, etc. It is suitable
for excavators and other large construction machinery.
Successful Use of Hydraulic Hose Assemblies
When assembling the hose, the recommended insertion depth has not been followed and the fitting has come off. After replacing the hose assembly, before crimping the new hose, mark the outer rubber of the hose according to the insertion depth indicated on our sample, and then insert the hose until the edge of the sleeve aligns with the marking line.
1,Question: What are your hose products?
Solution: The main material of our hoses is rubber. In order to cope with different hose usage conditions, there will be different hoses, such as high temperature resistant steam hoses, corrosion resistant chemical delivery hoses, ultra-high pressure cleaning hoses, Petroleum drilling hoses, etc.
2,Question: What certificates do you have?
Solution: Each hose we produce has obtained corresponding certificates, especially ISO and ABS system certificates, which is the recognition of our production capacity.
3,Question: How long is your lead time?
Solution: Usually the delivery period is 15 days
4,Question: How long is the service life of your hoses?
Solution: Different hoses have different service life, but the hoses we produce are relatively long-life hoses on the basis of standards
