Pandapipe has a state-of-the-art automated production line that is rigorously tested and validated at every step of the manufacturing process for ASTM A106 steel pipes. Ensure that the pipes meet the standard requirements and customer requirements. First, the static water test and electromagnetic inspection are carried out to detect whether there are defects inside and

“Pipe thickness” usually refers to the thickness of the pipe wall, referred to as W.T. The wall thickness of steel pipes is extremely important in the design, construction, safety and maintenance of pipelines. The wall thickness used in different usage scenarios is also different. The factors affecting the wall thickness include the type of material

What Is A Tee Pipe？ The tee pipe is also called a T-type pipe because its structure is similar to the letter “T”. It diverts the fluid from the main pipe to two branch pipes to achieve diversion. The tee pipes can be made into three pipe openings of the same or different diameters according

Core Role In industrial piping systems, there are many scenarios where the direction of the fluid needs to be changed. Our steel pipes are straight and cannot be bent. At this time, fittings used to change direction of a pipe comes into play. Its core is to achieve fluid transmission by changing direction. Types Of

Incoloy 800 is a nickel-iron-chromium alloy which was introduced in the year 1950 into the market to meet the need for a relatively low nickel content heat- and corrosion-resistant alloy. This is because the nickel was at that time designated a “strategic” metal. It has been commonly used over the past forty years for its

Cast iron pipes are widely used in building drainage systems, industrial pipelines, sewage treatment plants, and municipal infrastructure due to their excellent wear resistance, corrosion resistance, and pressure bearing capacity. Understanding and correctly selecting the right size of cast iron pipes is essential to ensure the stable operation of the system and extend its service

The chromium-nickel alloy Inconel 600 is designed for use at temperatures down to 2000 degrees F and down to lower levels of cryogenicity. Due to the content of nickel and weaker oxidising conditions resistant to chromium content, the alloy is resistant to the declining atmosphere and also to chloride stress corrosion cracking. Along with the

How does a pipe bending machine work? ‌Hydraulic pipe bending machine – “Great force creates miracles”‌ Use strong cold pressure to press steel pipes and other metal materials into the desired shape, and do not damage the material due to excessive temperature. The mold can be quickly replaced according to demand, and the efficiency is

Basic parameter system of steel pipe The size unit of steel pipe is based on the nominal pipe diameter as a parameter to indicate the size of the outer diameter of the pipe. The standard NPS uses the imperial unit. The larger the outer diameter, the larger the value. In the public service system, it
