steel pipe

In 2021, the trend of the steel export market will be affected by various factors such as the epidemic, shipping, tax adjustments, etc., especially the fluctuation of shipping prices, which has a particularly prominent impact on steel exports to the European and American markets. In June 2021, a regular Colombian customer was looking for spiral pipe resources for the new port project. The use is pile pipe, the product specification is ASTM A252 GR.3 800MM caliber. After receiving the customer's inquiry, we learned that the customer has very high product quality requirements and the delivery time is relatively tight. The Xinyue team provided relevant project experience, quality control documents and relevant qualification certificates as soon as possible, and also advised customers at the beginning of the project Use the form of tripartite manufacturing supervision to ensure qualified quality. In terms of maritime transport, Xinyue has always maintained good cooperation and interact...

 Piercing is the first process of deformation of hot-rolled seamless steel pipe, and its function is to pierce the solid tube blank into a hollow capillary tube. Due to the surface defects or eccentricity (uneven wall thickness) of the threaded capillary, it is difficult to eliminate or reduce it in the subsequent deformation process. Therefore, the quality of the perforated capillary has an extremely important influence on the quality of the hot-rolled seamless steel pipe. The tube blank piercing methods include pressure punching, push rolling piercing and skew rolling piercing. 1 Pressure punching Pressure punching is to put the heated square billet or corrugated steel ingot into the circular die, and then use the press to drive the punch to punch out the inner hole in the center part of the tube blank. Generally, the area of the punched inner hole is equivalent to or slightly larger than the gap between the blank and the circular die, so the deformation is very small, and the el...

In the middle of November, Xinyue received an inquiry of pipe fittings from customer in Singapore. As it is a replenishment of the project, they prefer stock , then can be arrived Singapore earlier . However, for the special material like ASTM A694/A694M-F42, there is no inventory in our warehouse, which need arrange new production ,usually takes 2 weeks. In order to solve the urgent needs of customer, the production department has adjusted the production plan and reduced the production time to one week. At the sames, Xinyue submits the delivery plans of air and sea transportation for customers' reference to meet the demands of arrival time. Air transportation to Singapore is able to arrive in the same day. Finally, due to the delivery time, the customer choose air transportation. At present, this batch of pipe fittings have arrived in Singapore. Relying on its unique geographical location, Tianjin has developed transportation. Tianjin port is the largest port in North China and on...

1. Bundle packaging 1) The steel pipes should be prevented from being damaged during bundling and transportation, and the bundling signs should be uniform. 2) The same bundle of steel pipes should be steel pipes of the same furnace number (batch number), the same steel grade, and the same specification. They should not be bundled in mixed furnaces (batch numbers), and those that are less than one bundle should be bundled into small bundles. 3) The weight of each bundle of steel pipes should not exceed 3000kg tons. The bundle weight can be increased with the consent of the user, but the maximum weight cannot exceed 5000kg. 4) When bundling flat-end steel pipes, one end should be aligned, the difference between the pipe ends at the aligned ends is less than 20mm, and the length difference of each bundle of steel pipes is less than 0.60m. However, the length difference of each bundle of steel pipes ordered according to the usual length is less than 1.5m, and the longest and second longest...

Precautions for seamless pipe loading 1. In order to prevent sinking, indentation, scratches and thread damage of the pipe body, it should be hoisted by disk crane, nylon belt or steel wire rope with protective spacer when loading. 2. When hoisting bundled steel pipes, no more than two bundles are allowed to be hoisted at the same time. When the weight of a single bundle exceeds 3000kg, only a single bundle is allowed to be hoisted. 3. It is not allowed to forcibly pull out the nylon belt or steel wire rope when it is pressed by the steel pipe or the pipe bundle. When loading wagons and delivering steel pipes for transportation to the user, due to the restrictions of the shipping conditions, the nylon belt or wire rope must be pulled smoothly to avoid strong collisions between the steel pipes or bundles or rollover of the bundles. Rough loading and unloading is strictly prohibited. 4. When using the tail hook to load and unload the pipe, the pipe end should be prevented from being dama...

What is a straight seam welded pipe? Straight seam welded pipe is a steel pipe with a straight weld seam parallel to the longitudinal direction of the steel pipe, also known as a straight seam steel pipe, which is made by bending a steel plate or strip and then welding the joints. The production process of straight seam welded pipe is simple, the wall thickness is uniform, the production efficiency is high, the cost is low, and its specification can be adjusted flexibly to meet the requirements of different pipe diameters, so it develops rapidly and is often used in various industrial production and urban pipeline construction. According to the production process of straight seam steel pipe, it can be divided into two types: high frequency straight seam steel pipe (ERW steel pipe) and submerged arc welding straight seam steel pipe (LSAW steel pipe). In recent years, most oil and gas pipelines in the world have required the use of straight seam welded pipes. Western developed countries ...
