Established in 1993, China Guanfa Valve Manufacture Co., Ltd. is specialized in the tube, tubing manufacturer and design of valves, hoses, tubes and pipes. Our oem and custom tubes, tubings products are suitable for acid, alkali, water, steam, seawater, coal gas and natural gas. They are widely used in petroleum, chemical, paper making, fertilizer, brewing and metallurgy. The use of specialized software of Pro/E and CAD has shorted the P&D and trial manufacture cycle, and greatly improved the service life and dependability of products.

1/8 to 1 in. OD #04/304L and 316/316L STMA213*/A269 (*nominal wall thickness, not minimum wall thickness). Available chemically cleaned and passivated to comply with ASTM G-93 and CGA G4.1
Available thermocouple cleaned to meet ASTM A632-S3. Until now mountain unicyclists had to put up with standard 24" inner tubes in their 24 x 3" tyres. Running a standard 24" inner means that the rubber of the inner tube is stretched paper thin and is vulnerable to pinch flats. This new 24 x 3" inner tube is correctly matched to the tyre's size, and fixes this problem. You can ride without fear of pinch-flatting any more! Ease of design exploration is illustrated by changing the density of the inner tube and showing the position of the waterline changes automatically after rerunning the feasibility study and regenerating. Practical applications of this example extend to the design of floats, buoys, or watercraft.

Standards: ASTM (ASME), A312/A312M, A554, A778. Surface: Pickled and annealed for industrial tubes, polished for decorate tubes(from 180G to 600G). Equipments: Automatic manufacturing line: 18 lines. Annealed line: 1 line. Automatic polishing machine: 3 lines. Straightness and rounding maching: 12 sets. Inspection: 1 set of hydraulic pressure testing, 1 set of eddy current controller. welding tubular metal using CO2, power 1kW to 6kW Industrial sector: general industrial Material: Stainless steel, 0.8-4mm thick A video showing this process is available search for “Profile welding system”. This is part of the reason why we can offer the best quality tubing. Each tube is handled and inspected many times during the drawing process. Each time a tube is handled, it is inspected. During the heat treating process they are handled with white gloves.
