PRODUCT DESCRIPTION
1. Liaocheng Changyi is committed to long-term development and creates high-quality products and services. Have the same pursuit of quality and service, stable and powerful, to maximize the consistency and stability of materials, product appearance and internal quality;
2. Galvanized square steel pipes and rectangular steel pipes are divided into the following grades
Q195—B grade, SS330, SPC, S185Q215—C grade, CS B type, SS330, SPHC, Q235—D grade, SS400, S235JR, S235JO, S235J2, Q345—SS500, ST52, S355JR
3. The galvanized layer can be customized, up to 280 grams.
4. The purity of zinc wire is 99.99%, and the zinc content is high, so that the weld seam of the pipe does not rust.
5. The diameter of zinc wire is 1.5mm, which has a good protective effect on welding.
6. No corrosion in the salt spray test for at least 8 hours.
7. In the passivation process, we have our own invention patent - automatic spraying system of galvanized pipe passivation solution, which ensures uniform adhesion, high passivation efficiency and beautiful appearance.
1. Classification of square and rectangular tube production process
Square rectangular tubes are divided into hot-rolled seamless square steel tubes, cold-drawn seamless square tubes, extruded seamless square tubes and welded square tubes according to the production process. Welded square tubes are divided into: (a) arc welded square tubes, resistance welded square tubes (high frequency and low frequency), gas welded square tubes and furnace welded square tubes; (b) straight seam welded square tubes and spiral welded square tubes according to welding points Minute
2. Material classification of square and rectangular tubes
Square tubes are divided into plain Carbon Steel square tubes and low alloy square tubes according to their materials. Ordinary carbon steel is divided into Q195, Q215, Q235, SS400, 20# steel, 45# steel, etc.; low alloy steel is divided into Q345, 16Mn, Q390, ST52-3, etc.
3. Classification of square and rectangular tube production standards
Square tubes are divided into national standard square tubes, Japanese standard square tubes, British standard square tubes, American standard square tubes, European standard square tubes and non-standard square tubes according to production standards.
4. Classification of rectangular tube section shapes
Square tubes are classified according to cross-sectional shape: (1) Square tubes with simple cross-sections - square square tubes, rectangular square tubes (2) Square tubes with complex cross-sections - flower-shaped square tubes, open-shaped square tubes, corrugated square tubes, special-shaped square tubes
5. Classification of surface treatment of rectangular tubes
Square tubes are divided into hot-dip galvanized square tubes, electro-galvanized square tubes, oil-coated square tubes and pickling square tubes according to surface treatment.
6. Classification of square and rectangular tubes
Square tubes are classified by use - decorative square tubes, machine tool equipment, machinery industry, chemical industry, steel structure, shipbuilding, automobiles, steel beams and columns, special purpose square tubes
7. Wall thickness classification of square and rectangular tubes
Rectangular tubes are classified according to wall thickness - extra thick rectangular tubes, thick rectangular tubes and thin rectangular tubes
