Screw thread of the car left LSAW steel pipe, standard number should be printed after the "Left"The word.7, such as product standards are not as special provisions, the chemical composition of LSAW steel pipe for acceptance by melting ingredients


The main process of casing pipe production line

The main process of casing pipe production line mainly consists of: descaling machine, flaw detector, pipe threading machine, screwing machine, hydraulic press, diameter machine, steel pipe high pressure fog spray paint machine, automatic length measuring, spray marking, packing equipment.1. Descaling machine: divided into two methods: steel brush rust removal and shot blasting, the main function is to treat the surface oxide scale of the raw material pipe;2. Flaw Detector: R134 refrigerant tube It is divided into two common methods: eddy current testing and ultrasonic testing. The main function is to detect the pipe material and check whether the pipe meets the production requirements.3. Pipe threading machine: Pipe thread CNC lathe is mainly responsible for the processing of pipe thread. Common buckle types are: short round buckle and long round buckle and special buckle;4. Screwing machine: It is divided into two types: the planetary clamping type and the inner curved surface clamping.

The main purpose is to tighten the coupling after the pipe thread processing to protect the thread;5. Hydraulic press: It is mainly to carry out water pressure test on the pipe body to check whether the steel pipe meets the production requirements;6. Path machine: mainly to check whether the inside of the steel pipe is smooth;7. Steel pipe high pressure fog spray paint machine: mainly after the pipe is finished, prevent the pipe from rusting in the outdoor and transportation process, and carry out automatic anti-corrosion spraying on the surface of the professional equipment;8. Steel pipe length measurement: The main purpose is to automatically measure the pipe number, furnace batch number, length, weight and other data, and then print the content onto the pipe surface to facilitate the use of the unit for identification;9. Marking machine: professional equipment for printing the pipe body mark;10. Packing: Bundling and discharging the finished pipe.

A/C Straight Ball valve Adapter For R410 /R22 on the level of the pipe

Oil drill pipe end threads using pipe, seamless steel pipe ends before threading usually after machining, including: cutting, car cylindrical, boring, chamfering and face processing. Tube end forms the thick thick, thick outer and internal and external thickened. Therefore, in order to eliminate the influence of uneven wall thickness and reduced pipe ovality, should be enlarged diameter punch and sizing ring compression method.

Various instruments required rigorous factory testing, test items include snails moment, tooth height, tooth, thread length, taper, tight moments. Reduced flaring punch when pipe ovality effect depends A/C Straight Ball valve Adapter For R410 /R22 on the level of the pipe wall thickness uniformity on a large level. Severe than those of the wall thickness is not as hot tube rolling machine rolling cycle-type steel (see cycle-type rolling machine rolling) after expanding punch, seamless end sizing by cold deformation process. After sizing, expanding and non-expanding transition zone, there may be different levels of residual stress, but may also occur due to internal and external appearance of punches and scratches caused by sizing the ring, leading to a slight stress corrosion.

To improve the strength of the weld zone, the pipe end is also used generally thickened. Ensure dimensional accuracy of machined steel, seamless steel pipe end sizing reduce ovality purposes. In order to improve the strength of the local threaded connections, pipe end thickening mainly used in petroleum and geological steel pipes. These processes are generally done on a dedicated machine once finished threading on both machines. After threading pipe ends due to wall thinning. Commonly used methods of sizing and expanding punch punch expanding and sizing ring compression two kinds. Using the method of increasing the pipe end thickened pipe end wall thickness.

Since the cold sizing, the pipe end is elastically deformed and also only a small amount of plastic deformation.  . Threaded throughout the local became the weak link in the pipe strength. In order to ensure compliance with regulatory requirements thread size. Deterioration in the quality of the appearance of the pipe end. Therefore, it should enhance the dimensional accuracy of rolled steel, used to prevent the pipe end sizing method. After sizing sleeve ends after black buckle ends of the wire when the car (car left tainted threaded surface) small quantity, can improve the yield. In addition, drill (tube) multi-use tool butt end of the connecting tube, the weld and heat affected zone is weak link strength. Mainly used for oil casing
