Application Scenarios & Case Studies
1. Metallurgical Plants
High pressure fluid transfer in steel and aluminum rolling lines relies on EN856 4SP hoses for hydraulic presses, delivering peak resistance to abrasion and thermal cycling. A 2023 case with a Turkish steelworks demonstrated a 30% reduction in hose failures after switching to Dayi EN856 4SP, attributed to the smooth cover's corrosion shielding and ISO 1436 pulse endurance.
2. Petrochemical Oilfields
Withstanding oil immersion, ozone, UV, and salt spray, hydraulic hose wholesale orders for offshore oil rigs favor the 4SP's four-spiral design for safety and long service life (documented 3+ years in simulation labs).
3. Heavy Equipment & Construction
Komatsu and Volvo excavators utilize OEM-certified EN856 4SP hoses for high-pressure boom cylinders, where minimum bend radius and pulse resistance are mission-critical. Fleet data shows 43% longer service intervals compared to EN853 2SN as per Hydraulics & Pneumatics Magazine.
4. High-rise Firefighting
Municipal firefighting fleets in Brazil adopted custom-made 4SP hoses for aerial ladders, enabling quick Hose-In-Hose deployment and minimizing risk of leakage under dynamic load shocks.

Professional FAQ: Hydraulic Hose Wholesale Technical Glossary
Q1: What material is used in EN856 4SP hydraulic hoses?
The inner tube is made from high quality synthetic rubber (NBR—Nitrile Butadiene Rubber), offering superior oil resistance, while the reinforcement is 4 spiraled high-tensile steel wires. The outer cover is smooth, abrasion and ozone-resistant synthetic rubber.
Q2: What do "pulse cycles" mean in hydraulic hose testing?
"Pulse cycles" refer to the number of pressure surges (cycles) the hose can withstand during dynamic operation. EN856 4SP typically endures 450,000+ pulses at rated pressure, exceeding ISO 1436 standards.
Q3: What is the minimum bend radius, and why is it critical?
Minimum bend radius is the smallest radius at which the hose can be bent without risking kinking or internal damage. For DN19 (3/4"), EN856 4SP offers a minimum of 130 mm, which supports tight installations and reduces hose fatigue.
Q4: What's the difference between braided and spiral reinforced hoses?
Spiral reinforcement (as in 4SP) uses multi-layered steel wires wound helically, ideal for high-pressure and pulse applications. Braided hoses involve wires interlaced in a crisscross, best for moderate pressures.
Q5: What is MSHA certification?
MSHA (Mining Safety & Health Administration) certification signifies a hose is flame-resistant and safe for use in hazardous, underground mining applications.
Q6: What end fittings can be used for hydraulic hoses made to order?
Options include crimped (permanent), reusable, and custom types: BSP, NPT, SAE, Metric, DKOL/DKOS. Selection is based on system compatibility and pressure requirements.
Q7: How is hydraulic hose traceability ensured?
Each hose batch is laser-marked with serial and batch number, production date, and factory code, allowing full traceability, supported by ISO 9001 quality systems.
