1、 Authoritative standard: rigorous certification for extreme deep-sea conditions The 17K crossover hose is designed and manufactured strictly in accordance with the API 17K Third Edition standard, which was developed by the American Petroleum Institute specifically for deep-sea flexible pipes and serves as a "passport" for high-pressure environments in the deep sea. The standard requires the core performance of hoses to withstand extreme hydrostatic pressure and internal transport pressure in deep sea environments, with a design life of several decades, and dual resistance to hydrogen sulfide and seawater corrosion, ensuring long-term stable operation in deep-sea environments of thousands of meters. 2、 Multi layer composite structure: precise design that combines rigidity and flexibility The excellent performance of the 17K crossover hose comes from the ingenious structure of multi-layer composite. Each layer of material and design is precisely adapted to deep-sea working conditions, balancing pressure resistance, corrosion resistance, and flexibility. 1. Inner adhesive layer: a corrosion-resistant barrier for medium safety Using * * 4.0mm thick UPE (ultra-high molecular weight polyethylene) or PTFE (polytetrafluoroethylene) * * materials, both of which have chemical inertness. It can resist the corrosion of corrosive media such as hydrogen sulfide, carbon dioxide, chloride in oil and gas, and has an extremely low friction coefficient, reducing pressure loss during transportation, preventing the adhesion of paraffin and hydrates, and ensuring the pure transportation of the medium. 2. Enhancement layer: the core skeleton for high-pressure load-bearing Composed of synthetic rubber, polyester fiber woven layer, and high-strength ultra flexible copper plated steel wire, it is the key to the pressure bearing of the hose. Polyester fiber woven layer is lightweight and high-strength, providing excellent tensile and torsional resistance; High strength copper plated steel wire, as the core pressure bearing skeleton, has extremely strong pressure bearing capacity and can resist deep-sea high pressure and internal fluid pressure. Copper plating treatment can also enhance the adhesion between steel wire and rubber, improving overall durability. 3. Outer layer+stainless steel armor: sturdy armor for deep-sea environments The outer layer is made of wear-resistant and weather resistant synthetic rubber, which can resist seawater immersion, UV aging, and reef friction; The outer layer is equipped with stainless steel armor to form a physical protective barrier, effectively resisting external impacts such as falling objects and fishing net dragging, and comprehensively protecting the internal structure. 4. Wide temperature adaptation: Suitable for complex temperature conditions The working temperature range is * * -30 ℃~+100 ℃ * *, which can withstand the low temperature environment of the deep sea and safely transport the warm oil and gas produced by the formation. The material stability is extremely strong. 3、 Core advantage: comprehensively surpassing traditional steel pipes Compared to traditional steel pipelines, the advantage of 17K crossover hoses is that they run through the entire process of installation, operation, and maintenance throughout the entire lifecycle Lightweight and easy to install: The weight is much lower than that of steel pipes of the same specification, and it can be transported in coils, easily crossing complex underwater terrain, greatly reducing installation difficulty and upper facility load, and saving construction costs. Strong corrosion resistance and long service life: The dual anti-corrosion design of the inner and outer layers has corrosion resistance far exceeding that of steel pipes, and can resist multiple corrosion such as seawater and hydrogen sulfide. The design life is longer, the maintenance requirements are extremely low, and the total life cycle cost is reduced. High flexibility and fatigue resistance: Excellent bending performance, can flexibly deform with the movement of floating bodies and the action of ocean currents, avoiding the risk of fatigue failure of rigid connection points, and adapting to deep-sea dynamic working conditions. High pressure and strong safety: The composite reinforced structure can withstand extreme pressure in deep sea. Before leaving the factory, it has undergone rigorous tests such as blasting and bending fatigue. Each hose meets the API 17K standard and is safe and reliable. 4、 Widely used: Core equipment for deep-sea oil and gas development The 17K crossover hose is designed specifically for marine engineering and is primarily used for flexible crossover between offshore production facilities. It can transport media such as crude oil, sulfur-containing crude oil, and natural gas, and is also suitable for scenarios such as gas injection, gas lift, FLNG high-pressure input, and firefighting water source transportation. Widely used in key links such as deep-sea oil and gas fields, subsea pipeline connections, and connections between offshore platforms and FPSOs (Floating Production Storage and Offloading Units), it is an indispensable core fluid transportation equipment for deep-sea energy development.
