Difference and application of seamless hot rolled pipe and cold drawn pipe in seamless steel tube
The general production of hot-rolled seamless steel pipe in the automatic tube rolling mill. Solid billet after inspection and clearance of surface defects, cut into required length, in the tube hole end surface of centering, then sent to a heating furnace, in punch in punch. While continuing to rotate and advance, in the roll and immediate action, tube gradually form a cavity, called capillary. Sent to the automatic tube rolling mill on rolling. Finally after all the entire thickness, sizing machine sizing, achieve specifications. Using continuous pipe mill production of hot-rolled seamless steel tube is advanced.1.2, in order to obtain smaller size and better quality of seamless tube, cold rolling, cold drawing must be used or combined method of cold rolling. Usually in two roller mill, rolling ring groove tapered plug pipe in variable cross section circular slot and the composition. Drawing is usually in single or double 0.100T chain drawbench.1.3, the extrusion method will soon heat the tube blank in the closed extrusion cylinder, the perforation bar and extrusion rod movement, so that extrusion parts from the smaller die hole extrusion. This method can produce smaller diameter steel pipes
What's the difference between a cracked carbon steel tube and a liquid carbon steel tube?
Test: cracking carbon steel pipe in addition to eddy current testing, but also to do ultrasonic testing, and liquid carbon steel tubes are generally only eddy current testing.s
What are the main aspects of precision steel tubes?
Products according to their application areas are divided into: automotive, precision machinery tubes; power plants, nuclear power tubes; titanium and titanium alloy tubes; chemical tubes; varieties include colored, black; seamless; welding; general and special-shapeds
How many fasteners are there in a ton of steel tubes?
The fastener generally refers to the intermediate connecting parts connecting two members, in the construction project for external diameter of steel pipe scaffold with 48mm fixation, the fastener is divided into rectangular fastener (cross directional fastener fastener) rotary fastener (universal movable fastener fastener) (a direct docking fastener fastener fastener) etc..s
Why seamless steel pipe called seamless steel pipe?
Seamless steel pipe is a hollow section, without the joint round, square, rectangular steel. Seamless steel tubes are made of ingots or billets made by piercing and are then made by hot rolling, cold rolling or cold casting. Seamless steel pipe with a hollow section, as pipe conveying fluid, compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, bike frame and construction using steel scaffolding.s
What is the production process of seamless steel tube?
The delivery status of hot-rolled seamless steel tubes is generally hot-rolled and delivered after heat treatment. Hot rolled seamless steel tube after quality inspection after staff strict hand picked in quality inspection should be carried out after the oil surface, followed by cold drawing experiments, hot rolling process should be carried out after the perforation experiment, if perforated expanding too large to carry out straightening correction. After straightening, the device is sent to the flaw detector by the transfer device to carry out the flaw detection experiment. Finally, the label is attached and the specifications are arranged and placed in the warehouse.s
