After purchasing a CNC plasma cutting machine, many customers will find such a problem in the process of cutting with a cutting machine. When cutting a steel plate, after the cutting is completed, a thin layer will be found on the surface of the plate. Rust. This problem is very unfriendly to our products. If customers see these things, the desire to buy will surely be greatly reduced. Therefore, we must deal with this issue. However, many customers do not know how to solve it. Today, Xiao Bian gave you two common methods:
welkin pipeline is one of the leading manufacturer, exporter and supplier of stainless steel buttweld fittings, carbon steel buttweld fittings, alloy steel buttweld fittings, cupro nickel buttweld fittings, nickel alloy buttweld fittings and duplex stainless steel buttweld fittings. While, there are many specialised types of fittings which can be manufactured, the most common types of fittings which we manufacture include pipe elbow, tee, reducers, cap, stub ends and special size pipe bends in both seamless and welded (100% X-Ray Tested/Radiography) form.
Buttweld fittings are manufactured in accordance with national and international product standards, while we can also produce fittings as per special specifications of our customers. In case of custom size fabricated buttweld fittings, the welding is done is carried out by qualified personnel.
Buttweld fittings are generally supplied with plain ends. However, on requests from our customers fittings be supplied with beveled ends in accordance with to ASME B16.25.

Seamless Buttweld Pipe Fittings
Seamless buttweld pipe fittings are manufactured from seamless pipes and tube by hot or cold extrusion, forming and machining process. We are a leading supplier and manufacturer of seamless buttweld pipe fittings in India. Most of the seamless buttweld pipe fittings in standard sizes and grades are available ex-stock for immediate supply to our customers.
Welded Buttweld Pipe Fittings
Seam welded buttweld fittings are produced from hot rolled stainless steel pipes. As per customer requirements, we can also manufacture and offer butt weld fittings manufactured from hot rolled plates, formed into half shells or segments and then welded on the seams.
Buttweld Fittings Grades
Stainless Steel Buttweld Pipe Fittings: ASTM A403 WP 304/ 304L/ 304H/ 316/ 316L/ 317/ 317L/ 321/ 310/ 347/ 904L/2205 Duplex Fittings
Marking & Packing
Products are packaged to ensure that there is no damage during transit. In case of exports, standard export packaging is done in wooden cases. All buttweld fittings are marked with Grade, Lot No, Size, Degree and our trade mark. On special requests we can also, make custom marking on our products.
Quality Assurance
At Metal Industries, all fittings and flanges are subject to strict inspection at each stage of the production process, from starting material purchasing to product dispatch. They are visually examined for conformity to ASTM, ASME, MSS, DIN, EN, and JIS codes and standards. Upon request, official certified Inspection Agencies can be called in to witness the material reports, dimensions and quality conformity of products.

Before explaining, we first do two small experiments to see the specific phenomenon:
Experiment 1: After high-temperature baking, the surface of the steel plate will become charred colors such as gray, black, brown, yellow, blue, iron red and other colors. This color does not look good and has no use value. The use of complex water can restore the original whiteness of the steel plate.
Experiment II: Using a plate printed with ink, after high-temperature grilling, so that the surface becomes dark brown and variegated, and then soaked in white water for more than 1 minute to make the black ash fade out of the sample. Parts of the lines covered by the ink are not whitened.
After the above two experiments, we can summarize the following two methods:
Method one: For high-temperature oxidized discolored steel plate can be washed off with steel whitening water, use of white water can restore the original white plate.
Method two: After pickling must be fully rinsed with water and wipe, to avoid secondary pollution, you can use manual polishing machine, a thin layer, it is easy to throw away.
Therefore, if we appear in the cutting process, the surface of the steel plate appears rust, then we do not have to panic, the majority of customers can follow Xiaobian method to remove him.
