Precision Seamless Tube Precision Rolled Tube

Brand ZCXH
Product origin Shandong,China
Delivery time 10-20 days
Supply capacity 1000 tons/ month

Precision Seamless Tubes and Precision Rolled Tubes excel in accuracy and performance. Seamless variants offer uniform strength, withstanding high pressure and minimizing leakage—ideal for hydraulic and high-precision systems. Precision rolled tubes feature ultra-tight tolerances and smooth surfaces, ensuring exact fits in machinery and instrumentation. Both boast exceptional dimensional stability, enhancing assembly efficiency. Made from high-grade steel, they deliver durability and excellent machinability, adapting to intricate fabrication needs. Suitable for aerospace, automotive, and medical equipment, these tubes blend precision engineering with reliable functionality, meeting the strictest industrial demands.

Overview

Precision Seamless Tube

Product Information

Mechanical couplers for parallel thread low carbon steel bars are core components in building construction (used for connecting reinforcing steel bars), and high-quality products of this type typically have the following key features:

1. Superior Material Performance & High Strength

Made of high-grade low carbon steel (e.g., Q235 or 45# steel, compliant with building material standards) with excellent tensile, yield, and impact resistance.
The mechanical properties of the coupler match or exceed those of the connected low carbon steel bars, ensuring the overall load-bearing capacity of the reinforced concrete structure is not compromised—even under dynamic or heavy loads (e.g., seismic forces, structural dead weight).

2. Precision Parallel Thread Design for Reliable Connection

Features precision-machined parallel threads (thread pitch, diameter, and tooth profile strictly adhere to industry standards like GB/T 1499.3 or ASTM A615). The thread fit is tight and uniform, eliminating gaps that could cause connection looseness.
Enables "full-thread engagement" between the coupler and steel bars: when installed correctly, the bar threads fully penetrate the coupler, distributing stress evenly across the connection and avoiding localized stress concentration (a common cause of connection failure).

3. Easy & Efficient Installation

No need for on-site welding or grouting—only requires matching pre-threaded steel bars to be screwed into the coupler (can be operated with standard hand tools or electric wrenches).
The parallel thread structure allows for quick alignment of steel bars, reducing installation time by 30%–50% compared to traditional welding methods. It also minimizes skill requirements for operators, ensuring consistent installation quality across projects.

4. Excellent Corrosion Resistance

Surface treatment options include hot-dip galvanization, electro-galvanization, or phosphating + anti-rust coating, forming a dense protective layer on the coupler surface.
Effectively resists corrosion from moisture, concrete alkaline substances, or outdoor environmental factors (e.g., rain, humidity), preventing rust-induced degradation of the connection over long-term use and extending the service life of the reinforced structure.

5. Stable Dimensional Accuracy & Consistency

All components (coupler body, internal threads, and auxiliary parts) undergo strict dimensional inspection (via precision measuring tools like thread gauges or calipers) to ensure uniform specifications.
No dimensional deviations (e.g., uneven thread depth, deformed coupler body) that could affect installation or connection strength, making the product compatible with standard low carbon steel bars of corresponding diameters (e.g., 16mm, 20mm, 25mm bars).

6. Wide Compatibility & Versatility

Compatible with various types of low carbon steel reinforcing bars (e.g., plain round bars, ribbed bars) commonly used in buildings, as long as the bars are pre-threaded to match the coupler’s thread specifications.
Suitable for multiple building scenarios, including high-rise buildings, bridges, tunnels, prefabricated concrete components, and underground structures—adapting to both cast-in-place and prefabricated construction methods.
