Steel pipe production process

- Oct 05, 2020-

(1) The head and tail of the metal pipe are butt jointed via way of means of unmarried-cord or double-cord submerged arc welding. After the metal pipe is coiled, it's miles repaired via way of means of automated submerged arc welding.

(2) Before forming, the metal pipe undergoes flattening, part trimming, part planing, floor cleansing and conveying, and pre-curving.

(3) Electric touch stress gauges are used to govern the stress of the cylinders on each facets of the conveyor to make certain the clean transportation of metal pipes.

(4) The metal pipe is reduce into person metal pipes with an air plasma slicing system.

(5) After slicing right into a unmarried metal pipe, the primary 3 metal pipes of every batch should go through a strict first inspection gadget to test the mechanical properties, chemical composition, fusion repute of the weld, the floor pleasant of the metal pipe and byskip non-unfavorable inspection to make certain the pipe production system Only after it's miles certified can or not it's formally placed into manufacturing.

(6) The elements with non-stop sonic flaw detection marks at the welds are re-tested via way of means of guide ultrasonic and X-ray. If there are defects, after repairing, they may undergo non-unfavorable inspection once more till the defects are confirmed.

(7) adopts outside manipulate or inner manipulate roll forming.

(8) The weld hole manipulate tool is used to make certain that the weld hole meets the welding requirements, and the pipe diameter, the quantity of misalignment and the weld hole are strictly managed.

(9) Both inner welding and outside welding undertake American Lincoln electric powered welding system for unmarried-cord or double-cord submerged arc welding, so that you can gain solid welding specifications.

(10) All welds after welding are inspected via way of means of a web non-stop ultrasonic automated flaw instrument, which ensures 100% non-unfavorable checking out insurance of spiral welds.If there may be a illness, it'll routinely alarm and spray the mark, and the manufacturing people can modify the system parameters at any time to put off the illness in time.(11) The butt weld of the metal pipe and the pipe in which the T-fashioned joint intersects with the spiral weld is all inspected via way of means of X-ray tv or filming.

(12) Each metal pipe undergoes hydrostatic stress test, and the stress adopts radial seal. Test stress and time are strictly managed via way of means of the metal pipe hydraulic microcomputer checking out tool.

(13) The pipe stop is machined to appropriately manipulate the verticality of the stop face, the bevel attitude and the obtuse part.

(1) The head and tail of the steel pipe are butt jointed through manner of way of single-wire or double-wire submerged arc welding. After the steel pipe is coiled, it's far repaired through manner of way of computerized submerged arc welding.

(2) Before forming, the steel pipe undergoes flattening, component trimming, component planing, ground cleaning and conveying, and pre-curving.(three) Electric contact strain gauges are used to control the strain of the cylinders on every aspects of the conveyor to make sure the easy transportation of steel pipes.

(4) The steel pipe is lessen into character steel pipes with an air plasma reducing device.

(5) After reducing proper right into a single steel pipe, the number one three steel pipes of each batch need to undergo a strict first inspection system to check the mechanical properties, chemical composition, fusion fame of the weld, the ground quality of the steel pipe and byskip non-destructive inspection to make sure the pipe manufacturing device Only after it's far licensed can or now no longer it is officially located into manufacturing.

(6) The factors with non-forestall sonic flaw detection marks on the welds are re-examined through manner of way of manual ultrasonic and X-ray. If there are defects, after repairing, they will go through non-destructive inspection over again until the defects are confirmed.

(7) adopts out of doors control or internal control roll forming.

(8) The weld hollow control device is used to make sure that the weld hollow meets the welding requirements, and the pipe diameter, the amount of misalignment and the weld hollow are strictly controlled.

(9) Both internal welding and out of doors welding adopt American Lincoln electric powered powered welding device for single-wire or double-wire submerged arc welding, so you can benefit strong welding specifications.

(10) All welds after welding are inspected through manner of way of an internet non-forestall ultrasonic computerized flaw instrument, which guarantees 100% non-destructive finding out coverage of spiral welds.If there can be a contamination, it's going to mechanically alarm and spray the mark, and the producing humans can adjust the device parameters at any time to get rid of the contamination in time.

(11) The butt weld of the steel pipe and the pipe wherein the T-original joint intersects with the spiral weld is all inspected through manner of way of X-ray television or filming.

(12) Each steel pipe undergoes hydrostatic strain test, and the strain adopts radial seal. Test strain and time are strictly controlled through manner of way of the steel pipe hydraulic microcomputer finding out device.

(13) The pipe forestall is machined to accurately control the verticality of the forestall face, the bevel mindset and the obtuse component.
