Due to vast experience & concerted efforts of all employees, we are known as a reliable supplier of API 5l Line Pipe, seamless pipes and ERW pipes. Our A633 Gr E factory customers in the world has about 4000 clients in 70 countries such as Bangladesh, Saudi Arabia, Iran, Iraq, United Arab Emirates, Qatar, Bahrain, Oman, Kuwait, Turkey, Egypt, Jordan, Philippine, Singapore, Malaysia, Indonesia, Thailand, Vietnam, South Korea, Japan, Sri Lanka, Bangladesh, Argentina, Brazil, Colombia, Guyana, United States Of America, Canada, Mexico, Jamaica, Germany, France, Italy, United Kingdom, Spain, Netherlands, Belgium.

Management information and high efficiency. Because of the rapid flow of A633 Gr E factory goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation

Laser cutting A633 Gr E factory has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the A633 Gr E factory cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.

In April 2018, our Philiphine customer purchased 1008 Tons API5 L Gr.B ERW&Q345B SMLS pipe A633 Gr E factory for offshore oildfield resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.

Chemical composition of 12Cr1MoV alloy steel plate: Carbon C: 0.08-0.15; Silicon Si: 0.17-0.37; Manganese Mn: 0.40-0.70; Sulfur S: allowable residual content ≤ 0.035; Phosphorus P: allowable residual content ≤ 0.035; Chromium Cr: 0.90-1.20; Nickel Ni: allowable residual content ≤ 0.030; Cu: allowable residual content ≤ 0.030; V: 0.15-0.30; Mo: 0.25-0.30.Delivery status of A633 Gr E factory, 12Cr1MoV alloy steel plate: delivered in heat treatment (normalizing, annealing or high temperature tempering) or non heat treatment status, and the delivery status shall be indicated in the contract.

In 2019, through the concerted cooperation of the enterprise team, the sales volume has grown steadily, and the annual sales volume has exceeded 300 million yuan.
