Hengshui Zhehan Rubber & Plastic Products Co., Ltd. is a manufacturer that has focused on industrial rubber and plastic hoses for years, supplying products to overseas markets where demanding worksite performance is non-negotiable. The Abrasive Conveying Sandblasting Hose range came out of direct, ongoing feedback from blasting contractors and fabrication shops. It wasn’t designed to be just another commodity hose. Instead, every material choice and production step was geared toward solving the specific failure points that drive up costs in abrasive transfer work: premature wear, pressure blowouts, stiff handling in cold weather, and aging in outdoor storage.
This Abrasive Conveying Sandblasting Hose was developed specifically for conveying hard abrasives like grit, steel shot, and quartz sand under pressure. It’s built to solve the common failures that plague standard hoses: rapid wear, insufficient pressure holding, kinking and clogging, and outdoor aging.
By combining precise manufacturing processes with quality rubber compounds, the hose delivers high abrasion resistance, reliable pressure capacity, and good flexibility. The result is less equipment downtime, fewer consumable change-outs, and noticeably smoother blasting and shot-blasting workflows.
For clients in construction machinery, shipbuilding, steel fabrication, and other heavy-duty industries, this hose provides a stable, safe, and longer-lasting abrasive conveying solution — helping you keep costs down and reduce on-site safety risks.
Steel structure engineering: Removing rust, mill scale, and old coatings on large steel frameworks, factory structural components, and bridge elements. The hose handles the high-volume abrasive flow these jobs demand.
Shipbuilding and heavy marine industry: Corrosion protection blasting on hulls, decks, compartments, and marine steel plates. It holds up in outdoor, humid, salt-spray environments and reliably conveys all types of blasting abrasives.
Construction machinery manufacturing: Shot-blasting and blast-cleaning of parts for excavators, cranes, loaders, and similar heavy equipment. Built for high-frequency, high-intensity continuous operation.
Hardware and mold processing: Deburring, descaling, and matte finishing on molds and cast metal parts. The hose suits precise, smaller-scale abrasive transfer on mid-sized and smaller blasting setups.
Petrochemical equipment: Anti-corrosion blasting on the external surfaces of storage tanks, pipelines, and process equipment. Handles high and low temperatures, resists aging, and works reliably in open-air plant conditions.
Infrastructure and bridge projects: Surface restoration blasting on bridge girders, guardrails, and steel infrastructure components. Performs well on long runs with multiple bends and high-load abrasive delivery.
The inner tube uses an NR/SBR wear-resistant synthetic rubber. Under ASTM D5963 abrasion testing, typical loss is below 50 mm³ per 1000 revolutions — more than 60% better than standard rubber hose. It handles high-speed conveyance of steel grit, quartz sand, copper slag, and other hard abrasives over the long term, reducing wall wear, extending service life, and lowering replacement costs.
The hose is reinforced with multiple layers of high-tensile textile cord, evenly wound for uniform strength. The standard working pressure is 1.2 MPa (12 bar), with a burst pressure reaching 3.6 MPa — a 3:1 safety factor. Under high-pressure operation, it resists bulging, delamination, and burst failures, delivering stable pressure performance and fitting continuous blasting work safely.
A custom modified rubber formulation gives the hose a working temperature range from -30 °C to 82 °C. It won’t stiffen or become brittle in freezing conditions, and it won’t soften or deform under high heat. This all-weather capability covers outdoor worksites in both northern and southern climates, hot workshops, and cold winter environments — offering far greater adaptability than ordinary abrasive hoses.
The hose wall is produced through a uniform forming process that gives it excellent bend performance. It handles tight-angle bends without collapsing or blocking abrasive flow, and its torsional fatigue resistance is solid. This makes it practical for complex site layouts, mobile blasting work, and confined spaces, where it helps prevent the common problem of kinked hoses stopping production.
The outer cover is a weather-resistant modified rubber. After 500 hours of QUV accelerated weathering testing, it shows no cracking or chalking. It also resists mild acids, alkalis, and light chemical attack. In outdoor conditions with sun, moisture, and salt spray, the hose resists aging and cracking, delivering up to 50% longer service life compared to standard products and significantly reducing maintenance shutdowns.

Never exceed the rated working pressure or temperature range. Before starting high-pressure blasting, check the hose body for damage and confirm all couplings are tight. This prevents abrasive leaks and burst hazards.
During blasting, avoid dragging the hose over sharp edges, running it over with heavy equipment, or kinking it sharply — all of which can weaken the hose and lead to leaks or failure.
Keep the hose clear during daily operation; don’t allow abrasive to sit packed inside, which causes localized rapid wear. After each job, blow out any remaining abrasive with compressed air.
Store the hose in a dry, ventilated place away from direct sunlight and chemicals. This slows rubber aging and meaningfully extends the working life of the hose.
Use couplings that match the hose’s inner diameter, and ensure connections are sealed tightly and securely, without misalignment or looseness.
Do not forcibly stretch or twist the hose during installation. Long-term stress from improper fit can cause delamination or deformation, compromising safety and performance.
For high-frequency, long-duration continuous operation, schedule routine inspections of the hose wall for wear. Replace aged or damaged hose promptly to avoid unplanned downtime and safety risks.
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, the minimum order quantity is just one length. We support both bulk purchases and smaller custom orders, and we keep sufficient stock on regular sizes for fast dispatch.
Q: Do you offer OEM customization?
A: Yes. We can customize non-standard inner diameters, lengths, special pressure ratings, and weather-resistant constructions. Customer logos can be printed, and packaging can be tailored to your requirements — all to match your equipment and project needs.
