Hydrostatic test Pipe to withstand a hydrostatic test without leakage through the weld seam or the pipe body. Jointers need not be hydrostatic tested provide the pipe sections used were successfully tested. Bend test No cracks shall occur in any portion of the test piece and no opening of the

The standard covers pipe sizes in NPS (National Standard Straight) from 1/8 inch to 48 インチ (10.3mm DN6 – 1219mm DN1200). It also complies with the nominal wall thickness specified in ASME B 36.10M. For sizes that are not covered by ASME B 36.10M, this standard specification can still be

First of all, the place or warehouse where ERW steel pipes are stored should be clean and well-drained, away from factories and mines that produce harmful gases or dust. Weeds and all debris should be removed from the site, and ERW straight seam steel pipe equipment accessories should be kept

This method has the highest productivity and is also the main production method of straight seam steel pipes. The brief production process of this device is to first bend it into a U shape, then press it into an O shape, and then mechanically expand it after welding the inside

Steel pipes are one of the most essential building materials used in the construction industry. These pipes are made of steel and are primarily used for conveying liquids and gases from one place to another. Steel pipes are used in various applications, such as in the oil and gas industry,

Black annealed pipes are a common type of pipe material commonly used to make furniture pipes, such as iron flower racks, table legs, chair legs, 等. This type of pipe has many advantages and is therefore widely popular in the furniture manufacturing industry. The material of black annealed tubes is

Seamless pipe is a type of pipe material with a seamless surface and appearance, commonly used in gas and solid pipelines. It can withstand high pressure and high temperature, and has excellent corrosion resistance, so it is widely used in fields such as petroleum, chemical, natural gas, medicine, shipbuilding, 等.

Strength of rectangular steel tubing When discussing the strength of rectangular pipes, it’s important to consider several key factors to make informed decisions. Strength isn’t a simple concept and typically involves various performance indicators. rectangular hollow section strength can be measured through different methods, including bending strength, 抗張力, and

There are six types of pipes and tubular goods.

Steel pipes are excellent conduits for conveying liquids and gasses in construction and industrial processes, as well as in everyday use at home or on the go. Steel pipes have a variety of features that make them different from other common pipe materials, however, so it’s important to know what
