On July 13, 2013, Litong held the first oath meeting "Product Quality Zero Defect Day", emphasizing that "without quality, everything is negative". In August 2013, the company's president Zhao Hongliang put forward the idea of "sample production \'\', which means that all products on the production line can be samples for customers, which fully reflects the company's emphasis on production. Product quality. 2013 In September, the steel wire braided hose pulse PK competition was held. Salt spray test of the fluid connector series products produced by Litong business department: the white zinc coating (more corrosion resistance) can reach more than 96 hours, and the color zinc coating can reach more than 72 hours , galvanized nickel alloy can reach a minimum of 480 hours and a maximum of 960 hours. The sales department has 75 employees, including 3 senior fluid technical engineers, 8 engineers and 15 professional technicians, who have mastered the use of fluid connections. A full set of basic technologies for the design and manufacture of equipment and rigid pipe assemblies. On January 11, 2020, Litong Petroleum Pipeline Products API 16D successfully obtained the fire safety certificate from Lloyds Register of Shipping (LR), the world's leading equipment company, for The company has won a new exploration of the international market. Passed. This certificate fully proves the excellent performance of Litong products, indicating that our company's production technology has reached the world-class level. Food-grade rubber hoses do not contain plasticizers and beverage delivery hoses The inner stainless steel wire reinforced plastic tube does not contain plasticizers, it is safe to use, colorless, odorless, and the inner wall is smooth. The outer layer of steel wire reinforcement makes it resistant to vacuum suction. High temperature of 120 degrees, half an hour at 150 degrees, can be autoclaved, radiation sterilized or Eto sterilized. Produced under strict quality control conditions to ensure the identity of this series of food-grade hoses, adding stainless steel protection rings to maintain It can avoid the damage of hose fracturing, kinking, severe corrosion and friction while being elastic.</div><div>The transportation hose is a new type of rubber material developed by our company. It has strong corrosion resistance in the transportation of strong acids and alkalis. The rubber hose is super wear-resistant, and the normal use time of a hose is 2,500 hours. The suction and discharge hose has excellent wear resistance and is mainly used to transport abrasive materials, such as sand and other bulk materials. Today, we will specifically introduce A sandblasting hose specially designed for sand conveying and sand discharge. Wear-resistant rubber soft joint pumps and valves, fire fighting equipment, pipelines with large vibration, and pipeline connections with frequent changes in cold and heat. Mainly used for raw water, sewage lifting and transportation, fire Pipeline transportation of chemical materials such as cooling circulating water, metallurgy, condensate water, and chemical industry in power plants, cooling dilution in petrochemical industry and flexible connection of long and short pipelines in other industries. Due to the high wear resistance of rubber, it is also suitable for Granular and powdered and cryogenic steam transport for all industries.
What raw materials are mainly used for the outer rubber layer of the material conveying hose?
