The Philippine customer who first met in August 2021 successfully received the first trial order of scaffold steel pipe and fastener products at the end of September, and then confirmed the new scaffold product order. The products cover four categories: steel plank, coupler, steel pipe and aluminum ladder. Because the current shipping cost is very high and has been rising, the customer wants us to maximize the space of the container and load as many goods as possible in each container. The two sides spend nearly a week to confirm the quantity of each product specification acceptable to each other, and then sign the contract. At present, this order has been scheduled for production, and all specifications of products will be ready for inspection and shipment at the end of November. https://www.tjxysteel.com/news/New-Scaffolding-order-from-Regular-Philippines-Customer-2054.html

Since the cooperation in 2017, our regular American customer have maintained good communication with Xinyue Steel. In recent years, the Chinese government has adhered to the "green and balanced trade development strategy". With the changes in the bilateral trade development strategy, this year, we once again ushered in both sides Three times of re-order cooperation. This project is mainly for structural steel pipes, with material ASTM A500 GRADE B. The length of the pipes is very strict and complex, ranging from 1 meter to 15 meters, and almost a single pipe is only with one pipe quantity. The wall thickness ranges from 9.53mm-50.8mm. Most of the specifications are thick-wall welded pipes. Compared with the conventional wall thickness, it is almost beyond the domestic production limit. In order to meet the needs of customers, we took the initiative to propose a seamless steel pipe replacement plan: 610*50.8mm thick wall thickness solution, which was highly appreciated by cust...

Everyone knows that when we transport all kinds of things, we need to check carefully, especially large-scale materials, which need to be checked two or three times before entering or leaving the warehouse. So how should the anti-corrosion spiral steel pipe be checked when entering and leaving the warehouse? What should be paid attention to in its transportation and loading and unloading? 1) How to check the entry and exit of anti-corrosion spiral steel pipes? 1. Carry out root-by-root inspection to ensure that the surface of the polyethylene layer is smooth and smooth, without dark bubbles, pitting, wrinkles, and cracks as a whole, and the overall color needs to be uniform. There should be no excessive corrosion on the surface of the pipe. 2. The bending degree of the steel pipe should be less than 0.2% of the length of the steel pipe, and its ellipticity should be less than or equal to 0.2% of the outer diameter of the steel pipe. The local unevenness on the surface of the whole pipe...

In July of this year, Xinyue received a power platform construction project from an old African customer in cooperation with the local government. The product is seamless pipe with total weight of 105 tons, the product specification is API 5L PSL1 X65, 457.2*12.7*1200MM. High steel grade seamless pipe is our advantage products. At that time, due to insufficient US dollar reserves of the customer, the order was delayed in landing. In the following months, the price of raw materials and the price of ocean freight continued to rise. Xinyue has also been regularly updating the market situation to its customers, and customers are also rushing to raise money after learning about the market situation. At the beginning of November, Xinyue received an email from a customer requesting to update the latest price, and then Xinyue and the customer discussed the relevant details of the contract on the phone. In order to avoid further price increases, it was also out of trust in Xinyue. The customer ...

Since 2015, Xinyue has been supplying galvanized pipes of size DN15-DN100 to a South African stockiest. The repeat 1~2orders were placed by each quarter, which has lasted for more than six years. In recent years, our regular customers in South Africa gradually expand their market from the basic hot dip galvanized pipe to pre-galvanized round pipe and square tube. And In this middle of June, the customer seized the good opportunity of the market fall, quickly confirmed the order of 120tons pre-galvanized steel pipe and hot-dip galvanized steel pipe. After the scheduled production, Xinyue QA team has carried out the strict testing of dimension & thickness of zinc coating. The production of hot-dip galvanized and pre-galvanized round pipes has been completed, and they have been smoothly sent to the port for shipment within one month. In order to protect the surface of galvanized pipe from being damaged by rain/water during the bulk carrier, we coated the external surface of galvanized...

Project location：Africa Product：Reducing Tee, Concentric Reducer Specifications： Reducing Tee 3”x 2” Concentric Reducer 3” Standard and material：ASTM A234 WPB Usage：Pipe connector Inquiry time：2022.02.15 Order time：2022.02.15 Shipping time：2022.02.30 Arrival time：2022.03.07 This time we want to introduce a regular customer in Africa. At the beginning of 2018, the customer chose Xinyue to cooperate for the first time, and ordered a batch of ERW steel pipe. The comprehensive and considerate service made the customer who feel the sincerity and intention of Xinyue. Of course, good service is only the first step. What really impresses customer is the high-quality products. All test data meet the requirements of the order, and have been well received by third parties and customer. With this good start of this order, no matter what steel products are needed, customer always consider Xinyue as the first supplier.In succession, They also cooperated with our company with pipe fittings,fire pipes...

Seamless boiler tube is a kind of boiler tube and belongs to the category of seamless steel tube. The manufacturing method is the same as that of the seamless tube, but there are strict requirements on the steel type used in the manufacture of the steel pipe. High-pressure boiler seamless tubes are often under high temperature and high pressure conditions when used, and the pipes will be oxidized and corroded under the action of high-temperature flue gas and water vapor. Steel pipes are required to have high durable strength, high resistance to oxidation and corrosion, and good structural stability. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, gas guide tubes, main steam tubes, etc. of high-pressure and ultra-high pressure boilers. 1. What is a seamless boiler tube hydrostatic test? The seamless boiler tube hydrostatic test is divided into two types: working pressure test and overpressure test. The purpose of the hydrostatic test is to te...

The quality inspection method of spiral pipe (ssaw) is as follows: 1. Judging from the surface, that is, in visual inspection. Visual inspection of welded joints is a simple procedure with various inspection methods and is an important part of finished product inspection, mainly to find welding surface defects and dimensional deviations. Generally, it is observed by naked eyes and tested with tools such as standard models, gauges and magnifying glasses. If there is a flaw on the surface of the weld, there may be a flaw in the weld. 2. Physical inspection methods: Physical inspection methods are methods that use certain physical phenomena for inspection or testing. The inspection of internal defects of materials or parts generally adopts non-destructive testing methods. X-ray flaw detection is the most commonly used method for non-destructive testing of spiral steel pipes. The characteristics of this detection method are objective and direct, real-time imaging by X-ray machines, softwar...

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...
