How to Reduce the Scrap Rate of ERW Steel Pipe in Manufacturing?

From the analysis data of ERW steel pipe scrapping, it can be seen that the roll adjustment process plays a very important role in the production of welded pipes. That is, in the production process, if the rolls are damaged or worn seriously, some rolls should be replaced in time in the unit, or a certain type of ERW welded steel pipe should be continuously produced in sufficient quantity, and the entire set of rolls should be replaced. When replacing the welded steel pipe, the roll needs to be adjusted accordingly to ensure the quality of the welded pipe. On the contrary, if the roll is not adjusted properly, it is likely to cause defects such as torsion, lap welding, edge fluctuation, indentation, scratches and even large ovality on the surface of the welded pipe on the protrusion and the pipe body. The following is an introduction to the operation method of roll adjustment that should be mastered when changing rolls. First of all, if the specification of ERW steel pipe should be cha...

Xinyue steel starts a cooperation journey with Malaysian customer

Product: 5D bends Material: API 5L x65 PSL2 NACE MR-0175 Specification: 711*23.83mm Order quantity: 45 degree 5D bend and 90 degree 5D bends User destination: Malaysia Inquiry received time: Sep 29th, 2021 Signed order time: Oct 18th, 2021 ETD: Jan 10th, 2022 The customer is a trader in Malaysia. It is the fist time to contact with Xinyue and create business cooperation. At the beginning of receiving enquiry, it refers to steel pipes only. After deep understanding of Xinyue with faster delivery time, competitive price, rich project experience and previous successful cases sharing, customer changed original plan of transferring pipes to Korea for hot bending process and decided to cooperate with Xinyue and ship bends to Malaysia directly. Deserve to be mentioned, these bends should meet with strict requirements including seamless steel pipe, large diameter, thicker wall, sour service material meeting with NACE MR-0175 hardness, complicated tests and tightly controlled tolerance, which l...

Steel Strand ,Anchorage and Equipment Order

This product covers anchors, steel strands, equipment and other products Project Location: Philippines We knew each other in March 2021 Successfully cooperated with steel pipe order at the begin of May. 「Trial order」 Laid a good foundation for later cooperation Received inquiry on December 15 Confirmed Contract On December 23, 2021 The customer is a local builder in the Philippines In May,2021, after receiving the first order product, the customer was full of praise for the product quality and decided to establish a long-term cooperative relationship with Xinyue Steel. Due to the repeated epidemic, the progress of local engineering projects in the Philippines basically stagnated. But in the meantime, we keep good communication together and always send the latest international industry information to customers at the first time. At present, the epidemic situation has improved, the project is about to start, and there is an urgent need to purchase a batch of products. The quantity of eac...

Stainless steel pipe and flange from Xinyue Steel to Uzbekistan

Project Location: Uzbekistan Products: stainless steel pipe and flange Size: 60.3-377MM Standard: ASTM A312 904L & TP321 Inquiry time:15th Mar, 2022 Purchase time: 10th May, 2022 Shipping time: 4th Dec, 2022 Estimated Arrival time: January, 2023 The project I would like to share with you today is the stainless steel seamless pipe and flange exported to Central Asia, which is the second cooperation with this customer. The first order is ordinary seamless tube, but the material of this contract is special, 904L, with large diameter and thin wall thickness, which requires the manufacturer to have strong control ability to meet the standard. Xinyue has exported a lot of stainless steel products in recent years, from the technical requirements, related testing, shipping packaging, have a set of their own perfect process. After receiving the inquiry, Xinyue sales and technical team carefully studied the standards and specifications, according to the requirements of customers to provide s...

Application of seamless steel pipe in construction industry

Among the many pipeline materials, the most practical one is seamless pipe (SMLS), which is a relatively powerful pipeline material, not only because of the wide range of application fields and scope of this pipeline material, but more importantly, Because the quality of seamless steel pipe is very good, the quality of seamless steel pipe is the reason why this pipe material can be promoted and developed in the industrial field, the quality of seamless steel pipe is very good, this is the complex production process of seamless steel pipe Determined, the biggest feature of seamless steel pipes is that there are no seams on the pipe wall (capable of high pressure), while ordinary pipes have obvious seams, because of the small feature of seamless steel pipes, this kind of Types of piping materials can be used and promoted in the industrial field. Seamless steel pipes are widely used. General-purpose seamless steel pipes are rolled from ordinary carbon structural steel, low-alloy structura...

Precautions for cleaning seamless pipes

When processing seamless tubes in seamless steel tube factories, pickling is used. Pickling is an indispensable part of most steel pipes, but after pickling seamless steel tubes, water washing is also required. Precautions when washing seamless tubes: 1. When the seamless tube is washed, it needs to be carried out in a flowing clear water tank, so as to avoid secondary pollution. When washing, the seamless steel tube needs to be completely immersed in water. At this time, the sling should be loosened and lifted up and down three times Up to four times. 2. When the seamless tube is washed with water, it is necessary to clean the water in the steel pipe to avoid water corrosion and oxidation of the steel pipe. Therefore, it is very necessary to process the solvent as soon as possible. 3. When the seamless tube is washed with water, it should be noted that it cannot cross the pickling tank to avoid accidents, slipping or falling into the acid tank and being corroded by residual hydrochlor...

Raw material and production process of steel

In daily life, people always refer to steel and iron together as “steel”. It can be seen that steel and iron should be a kind of substance; in fact, from a scientific point of view, steel and iron have a little Different, their main components are all iron, but the amount of carbon contained is different. We usually call “pig iron” with a carbon content above 2%, and “steel” with a carbon content below this value. Therefore, in the process of smelting iron and steel, iron-containing ore is first smelted into molten pig iron in a blast furnace (blast furnace), and then the molten pig iron is put into a steelmaking furnace to be refined into steel. Then, steel (steel billet or strip) is used to make steel pipes, for example, carbon steel billets can be made into steel pipes with hollow sections through hot rolling and cold rolling processes (carbon steel seamless tubes) The manufacturing process of seamless steel tubes is mainly divided into two major steps: 1. Hot rolling (extruded seam...
