Structural Steel Pipe. A wide range of applications rely on structural steel pipe for strength and stability. Gnee steel supply welded and seamless pipe for structural applications to customers in all industries. As a leading steel pipe supplier, Gnee steel offers a large inventory of pipe and tubing sizes from 1/8” NPS to 48” NPS.
A192 carbon steel pipe Application: It is applicable to seamless carbon steel boiler tubes with minimum wall thickness for high pressure and steel tubes for superheaters.
The tensile strength of ST42 Carbon Steel Pipe shall not be less than 42kgf/mm2, which is 420MPa.ST42 Carbon Steel Pipe is a German standard seamless steel pipe, which is widely used. German standard seamless steel pipes for general purposes are rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output, and are mainly used as pipes or structural parts for fluid transportation .
These Alloy steel pipes & tubes are used in different application industry like oil refineries, chemical plants, fertilizers plants, petrochemicals plants and sugar mills etc.
Precision steel pipe is a kind of seamless steel pipe material with high precision and bright inside and outside after cold rolling. Because the inner and outer walls of the precision steel pipe have no oxide layer, withstand high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks, etc., it can be done, so it is mainly used to produce pneumatic or hydraulic components, such as cylinders or cylinders, which can be seamless pipes.
Features
1, the outer diameter is smaller;
2, high precision can do small batch production;
3, high precision cold drawing finished products, good surface quality;
4, steel pipe cross section is more complex;
5, the steel pipe performance is better, the metal is dense, often used in the manufacture of mechanical structures, hydraulic parts, auto parts and so on.
Precision steel pipe main material: 10 #, 20 #, 35 #,45 #,40 Cr, 25 mn. 37 mn5, St35 (E235), St37.4, St45 (E255), St52 (E355) light pipe mechanical process performance are excellent, steel pipe can bear high pressure, especially suitable for hydraulic machinery, and automobile air conditioning refrigeration industry. Steel pipe can be cold bending deformation at any Angle, flaring, flattening without cracks, suitable for various bending deformation of steel pipe processing industries.
Our company specializes in the production and sale of alloy high-pressure pipe fittings and high-pressure boiler tubes. The company's steel pipes are complete in model, excellent in quality, high temperature resistance, corrosion resistance, and wear resistance, meeting the needs of industrial production. The price is reasonable, the inventory is sufficient, and we have won the trust of old customers. High-pressure boiler tubes are important industrial equipment for the production of various products. They can transport high-temperature and high-pressure fluids for various products. The application range of high-pressure boiler tubes is getting wider and wider.
Hastelloy C-276 Stainless steel pipe
Hastelloy C-276 alloy is one of the few materials that can be used in hot concentrated sulfuric acid solution It is mainly resistant to wet chlorine, various oxidizing chlorides, chloride solutions, sulfuric acid and oxidizing salts, and has good corrosion resistance at low and medium temperatures. Therefore, in the past 30 years, it has been widely used in harsh corrosive environments, such as chemical industry, petrochemical industry, flue gas desulfurization, pulp and paper making, environmental protection and other industrial fields.
1. For pipelines. Water, gas pipes, steam pipes, and oil and gas trunk lines. 2. Tubes for thermal equipment. Superheating pipes, high temperature and high-pressure boiler pipes for locomotive boilers. 3. For the machinery industry. Aviation structural tubes, automobile axle tubes, tractor structural tubes, etc.
Performance and application of material ST37: the material has good performance, that is, through cold rolling, it can obtain cold rolled strip and steel plate with thinner thickness and higher precision, with high straightness, high surface finish, clean and bright surface of cold rolled plate in Taiwan Strait, easy to be coated, various varieties, wide application, high stamping performance, non aging, and low yield point.
