The HDPE Krah pipe machine is especially divided into 2 major types: one is that the common high-frequency pipe attachment machine, and therefore the alternative is that the stainless-steel HDEP Krah pipe machine. The high-frequency pipe attachment machine is especially accustomed manufacture varied iron pipes, water pipes, etc.; The stainless-steel HDEP Krah pipe machine is especially accustomed manufacture varied stainless-steel ornamental pipes, moreover as varied automobile exhaust pipes, device pipes, fluid pipes, edible pipes, etc. What square measure the assembly method and weld treatment of the HDPE Krah pipe machine? Next, allow us to take a glance.

Here is that the content:

l Weld process of HDPE Krah pipe machine


The production method of the HDPE Krah pipe machine

(1) The raw materials of the HDPE Krah pipe machine square measure strip steel coil, attachment wire, and flux. Strict physical and chemical inspections square measure needed before investing.

(2) Joint of strip steel head and tail, adopt single wire or double wire submerged arc attachment, once turbinate into steel pipe, adopt automatic submerged arc attachment to repair attachment.

(3) Before the HDPE Krah pipe machine is created, the strip is leveled, trimmed, planed, surface clean, conveyed, and pre-curved.

(4) The HDPE Krah pipe machine uses electrical contact pressure gauges to manage the pressure of the cylinders on either side of the conveyor to make sure the sleek delivery of the strip.

(5) HDPE Krah pipe machine adopts external management or control roll forming.

(6) The weld gap management device is employed to make sure that the weld gap meets the attachment necessities, and therefore the pipe diameter, the quantity of arrangement, and therefore the weld gap square measure all strictly controlled.

(7) Each internal attachment and external attachment adopt yank Lincoln electrical attachment machines for single-wire or double-wire submerged arc attachment, to get stable attachment quality.

(8) The welds welded by the HDPE Krah pipe machine square measure all inspected by a web continuous inaudible automatic flaw tester, that guarantees 100 percent non-destructive testing coverage of spiral welds. If there's a defect, it'll mechanically alarm and spray the mark, and therefore the production staff will regulate the method parameters at any time in step with this to eliminate the defect in time.

(10) Once the HDPE Krah pipe machine cuts into individual steel pipes, every batch of steel pipes should bear a strict initial review system to visualize the mechanical properties, chemical composition, fusion standing, surface quality of the steel pipes, and non-destructive inspections to make sure solely once the pipe-making method is the qualified will or not it's formally placed into production.

Weld process of HDPE Krah pipe machine

1. If the gap is simply too giant, the proximity impact is going to be reduced, the eddy current heat is going to be scarce, and therefore the HDPE Krah pipe machine weld can have poor intergranular joints, leading to non-fusion or cracking.

2. If the gap between the HDPE Krah pipe machine is simply too little, the proximity impact can increase, and therefore the attachment heat is going to be overlarge, inflicting the weld to burn; or the weld can kinda deep pit once being extruded and rolled, which can affect the surface quality of the weld.

After the 2 edges of the tube, blank square measures are heated to the attachment temperature, below the squeeze of the squeeze roller, a typical metal crystal grain is created to infiltrate and crystallize one another, and at last, a firm weld is created. If the extrusion force of the spiral steel pipe is simply too little, the number of common crystals shaped is going to be little. The weld metal strength of the Krah Pipe machine can decrease, and cracks can occur once the force is applied; if the extrusion force is simply too giant, the liquefied metal is going to be squeezed out the weld seam not solely reduces the strength of the weld seam, however additionally produces an oversized range of internal and external burrs, and even causes defects like attachment lap seams.

Eagle Co. is found at QINGDAO, maybe a skilled manufacturer to supply giant diameter HDPE/PP spiral profile wound pipe production lines. We tend to square measure thriving to produce all of the globes with spiral profile wound pipe production lines from DN300mm to DN5000mm and have quite ten years of expertise. We tend to target developing and producing the technology and instrumentation to supply giant diameter HDPE/PP spiral profile wound pipe, HDPE spiral tank, fittings, manhole, etc. Our product embraces Krah Pipe, HDPE/PP social Profile wound Pipe Machine, Spiral Tank Winding Machine, mandril (production tool), single wall furrowed pipeline, hole boring machine, HDPE spiral tank attachment machine, etc. If you're inquisitive about Krah machine, corrugated Krah machine, Krah Pipe machine, HDPE Krah pipe machine, you'll be able to attend our website for consultation, our website is www.krahpipe.net.
