No Joint Brass Seamless Coil Tube For Oil Pipe And Hydraulic Tube, Or Matching With High-Speed Railway
1. Description
Brass coil, technically unlimited lengthgenerally 5mm-70mm in diameter and 0.1cm-5.0mm in thickness, is made of common brass and lead brass. See the following list for specific materials. Brass coil is widely used in chemical, mechanical, electronic, power, textile, rubber, food, equipment, aviation, aerospace, communication, petroleum and other industrial fields.
A. Brass coil is economical because it is easy to process and connect, so it can save material and total cost, stability and reliability, and can save maintenance.
B. Brass coil is portable for internal threaded pipes of the same internal diameter, and the thickness of ferrous metal is not required for copper pipes. When installed, the transportation cost of copper pipe is smaller, the maintenance is easier, and the occupied space is smaller.
C. Brass coil is easy to connect copper can change shape, because copper pipe can be bent and deformed, it can often be made into elbow and joint, smooth bending allows copper pipe to bend at any angle.
D. Brass coil is safe, no leakage, no combustion, no toxic gas, corrosion-resistant.
