✅ Main features of carbon steel hose connectors:

1. High strength and high pressure resistance

Carbon steel has excellent mechanical strength and is suitable for making hose connectors for medium and high pressure working conditions. With steel wire braided or wound hoses, the working pressure can usually reach 10-45 MPa, and some structures can withstand higher pressures.

2. Stable structure, safe and reliable

The tail of the connector is usually designed as a barbed or serrated reinforced structure, which is firmly connected to the hose by compression sleeve crimping (using a pipe crimping machine), and is resistant to pulling and impact.

3. Rich connection forms

Carbon steel connectors can be processed into various standard structures:

Threaded connection: BSP, NPT, Metric, JIC, ORFS, etc.;

Flange connection: ISO 6162 (SAE flange) is common in high pressure and high flow conditions;

Card sleeve type: commonly used for hard pipe and hose connection;

Welding type: suitable for special pipeline modification.

4. Surface anti-corrosion treatment

To enhance corrosion resistance, the surface of carbon steel joints is usually treated, such as:

Electrogalvanizing (blue and white zinc, colored zinc): general use in industry;

Phosphating blackening: rust-proof and beautiful;

Zinc-nickel alloy plating: improves salt spray corrosion resistance and can be used in outdoor and coastal environments;

Plastic spraying or anti-corrosion coating: suitable for oil fields or chemical environments.

5. Cost-effective

Compared with stainless steel or copper joints, carbon steel joints are more affordable without sacrificing strength, and are suitable for most general industrial or engineering scenarios.

⚠️ Usage restrictions:

Not suitable for highly corrosive media or high humidity environments, such as salt water, strong acids and alkalis, etc., stainless steel (such as 316L) joints should be used instead;

Rust prevention needs to be checked regularly, especially for outdoor or coastal operating equipment;

Do not repeat crimping and use, and carbon steel compression sleeves are prone to fatigue cracks or sealing failure after secondary use.

? Typical application scenarios:

Engineering machinery hydraulic system (excavator, crane, bulldozer)

Hydraulic oil station, hydraulic cylinder and pump valve connection

High-pressure oil pipe connection in coal mines and metallurgical equipment

Cooling or hydraulic system of continuous casting and rolling equipment in steel plants

Quick connection of general industrial fluid pipelines

✅ Summary:

Carbon steel hose connector is a durable, reliable and industrial-grade connector suitable for high-pressure working conditions. It is the most common and economical type of connector in hydraulic and industrial hose systems, suitable for most normal temperature, high pressure and non-corrosive use environments.
