Grenada Pipe Co., Ltd. Shandong Liaocheng seamless steel pipe wholesale and retail: according to different production methods can be divided into precision tubes, hot-rolled tubes, cold-rolled, cold-drawn tubes, squeeze tubes, hot rolled seamless pipe generally automatic rolling the pipe mill production, solid tube surface defects after inspection and clear cut into desired length, end to end in the perforated tube and then sent to the furnace heating the surface-centering punch a hole in the hole while continuing to turn and move forward in the roll and Head of the role, gradually formed within the cavity, said tube capillary, low-pressure boiler tubes wholesale, and then sent to rolling and finally by the automatic rolling machine reeling machines are wall thickness, the sizing mill sizing, to specifications the use of continuous production of hot-rolled seamless pipe mill is more advanced methods putting up get smaller size and better quality seamless steel tubes, cold-drawn or method must be cold-rolled combination of the two is usually in the second performed on a roller mill, steel pipe in the hole becomes circular hole section and a tapered head tank immobile consisting of rolling, drawing generally single chain or double chain drawing machine extrusion upcoming heating good perforated tube placed in bars and extruded rod move together in a closed extrusion cylinder that is extruded from the extrusion die hole smaller. Precision seamless steel tubes is a high-precision processing after the passage of a cold rolling; full name: precision cold-rolled seamless steel tubes. Because precision seamless outer wall oxide layer, to withstand high pressure without leakage, high-precision, high-quality finish, cold deformation, flaring, flattening without cracks, etc., so the main pneumatic or hydraulic components used in the production of products such as cylinder or cylinders are seamless pipe. Thick-walled seamless steel pipe more common materials include: 10 #, 20 #, 45 #, 16Mn and so on. Company goals: Our staff have the knowledge and trading experience of steel materials. Strength of the company, customers can provide various services, we would like to be honest, friendly cooperation, create brilliant! Shandong Grenada steel plant mainly produces the outer diameter 177mm-377mm, wall thickness of 10mm-100mm high-quality genuine seamless. Roll pipe mill can produce material 20 #, Q345b outer diameter 400-1600mm, wall thickness 20-60mm roller tubes can be cut to length to 16 meters. Joint venture to build production plant covers an area of ??500,000 square meters, is one of the largest local production plant, where to buy good course Liaocheng seamless steel pipe to find customers evaluate Grenada: Grenada Shandong seamless steel pipe manufacturer long been customers concerns customers from all regions of the trust I plant product brand, quality requirements, has high-quality service. Client Manager Wu: Our company has been co-owner and Xian three years, low-pressure boiler tubes complete, they are our long-term supplier of seamless steel they produce material fits the needs of our company, the quality is very strong, they sales and after-sales service staff attitude is also very good, we are very satisfied with the agreement that the company, it is particularly recommended to our friends! Grenada Pipe Co., Ltd. Shandong Liaocheng seamless steel pipe wholesale and retail: according to different production methods can be divided into precision tubes, Jilin low-pressure boiler tubes, hot-rolled tubes, cold-rolled, cold-drawn tubes, squeeze tubes, hot-rolled Generally in the automatic seamless pipe mill production, solid tube surface defects after inspection and clear cut into desired length, end to end in the perforated tube and then sent to the furnace heating the surface-centering punch on the punch in the hole while continuing turn and move forward, low-pressure boiler pipe prices, the role of the roll and the plug, gradually formed within the cavity, said tube capillary, and then sent to rolling and finally by the automatic rolling machine reeling machines are wall thickness, the sizing sizing machine, to specifications require the use of a continuous production of hot-rolled seamless pipe mill is more advanced methods putting up get smaller size and better quality seamless steel tubes, cold-drawn or both must be combined with The method is usually cold rolling the two-roll mill, steel rolling circular hole in the change in cross-section and a tapered plug the hole groove immobile composed, drawing generally in a single chain or double chain drawing extrusion method is about to be placed in a sealed tube heating good squeeze perforated cylinder rod moves together with the extruded rod, the pressing member is extruded from the die hole on a smaller machine.
