Steel pipe is an important material widely used in construction, engineering, petroleum, chemical industry, aerospace, and other fields. Among the many varieties of steel pipes, K235D steel pipe has attracted much attention for its high-quality performance and wide application fields. First, the

1. Selection of raw materials for cold-drawn seamless steel pipes To save costs, some seamless steel pipe manufacturers will choose round steel produced by small steel mills for processing, but the round steel produced by these small steel mills will contain many impurities, bubbles, interlayers, p

As a common metal pipe, stainless steel pipes are widely used in all walks of life. As one of them, 10050 stainless steel pipes have unique characteristics and advantages and are very popular in the market. 1. Characteristics of 10050 stainless steel pipes 10050 stainless steel pipes are a speci

First of all, we need to store the spiral steel pipes in the warehouse, not store them in the open air, and we need to ensure that the storage in the warehouse is clean. Tidy and well-drained. If there are weeds or other debris on the ground, they need to be cleaned and stored. This is to keep the s

(1) Preferred pipe materials When selecting steel pipe materials, metal materials are generally considered first. When metal materials are not suitable, non-metal materials are then considered. For metal materials, steel pipes are preferred, and non-ferrous metal materials are considered later. Amo

As a common metal material, steel pipe is widely used in all walks of life. As one of the special material steel pipes, 40CR steel pipe has also attracted much attention for its performance and use. 1.40CR steel pipe material characteristics 40CR steel is an alloy structural steel with high stre

There are many types of heat treatments for stainless steel pipe fittings, including solution treatment, stabilization treatment, stress relief treatment, and weld heat treatment. 1. Solution treatment is to heat stainless steel pipe fittings to the austenite zone to fully dissolve chromium and o

What is normalizing steel pipes? Normalizing steel pipes is a heat treatment that improves the toughness of steel. After the steel component is heated to 30~50°C above the Ac3 temperature, it is kept warm for some time and then air-cooled. The main feature is that the cooling rate

20Cr precision rolled steel pipe, as an important steel product, has a wide range of applications and unique advantages and characteristics. Below we will discuss in depth the characteristics, advantages, and applications of 20Cr precision rolled steel pipes in different fields. 20Cr precision ro

The anti-corrosion spiral steel pipe for water supply and drainage is a layer of polyethylene (PE) resin, ethylene-acrylic acid copolymer (EAA), epoxy (EP) powder, and non-toxic polypropylene (PP) with a thickness of 0.5 to 1.0 mm melted on the inner wall of the steel pipe. Or steel-plastic composit

When welding steel pipes, the following preparations should be made for the steel pipe mouth: (1) Remove floating rust, dirt, and grease from the interface. (2) When the steel pipe is steam welded or mechanically cut, the cross-section should be kept straight to ensure the concentricity of the ste

304 stainless steel welded steel pipe has relatively good corrosion resistance, heat transfer efficiency, and high-pressure resistance. After the welds of 304 stainless steel welded steel pipes are welded, they must be pickled and passivated. The pickling and passivation of the welds are carried out

There are strict technical requirements for the installation and use of spiral steel pipes, which must be carried out according to actual conditions and operating procedures must be followed to ensure safety and quality. During general use, spiral steel pipes need to pay attention to the following p

First of all, we must choose a suitable storage place, clean it, have good ventilation, and be free of debris and harmful gases. Steel surfaces should be kept clean to avoid corrosion. If it is a relatively expensive metal product, you can consider storing it in a sealed warehouse, but pay attention

35CrMo alloy seamless steel pipe is a widely used material and plays an important role in various industries. This type of steel pipe is popular for its excellent performance and reliability. First, the characteristics of 35CrMo alloy seamless steel pipe 35CrMo alloy seamless steel pipe are famou

Q355 is a high-quality low-alloy high-strength structural steel. It is the new name of the old standards 16Mn and q345. Since the q345 specified in the original GB/T 1591-2008 standard cannot be synchronized with the EU S355, the National Standards Committee issued a new regulation GB/T 1591-2018, w

1. Product introduction of 20G high-pressure boiler steel pipe Boiler steel pipes are used under high temperatures and high-pressure conditions, so compared with general-purpose steel pipes such as structural pipes, their service conditions are harsh. If there is a problem with any steel pipe in th
