Overview of tubing

Oil pipelines are pipelines that transport crude oil and natural gas from oil and gas formations to the surface after drilling is completed, and they are used to withstand the pressure generated during the extraction process. Oil pipe：tubing Tubing specifications: 8-1240×1-200mm The outer diameter of the tubing is generally 60.3 mm to 114.3 mm. Tubing end processing forms are: no thickening with thread and collar, external thickening with thread and collar, flat end, no thickening with thread and collar, external thickening with thread and collar.

The difference between hot galvanized sheet and cold galvanized sheet

Zhongtang Iron And Steel (Shandong) Group Co.,Ltd. is a well-known color coated plate company, the company integrity management, to ensure the quality of color coated plate, the following talk about the difference between hot galvanized plate and cold galvanized plate: 1, hot galvanized sheet generally thicker zinc layer, about 10um or more, strong anti-corrosion ability. So it is a commonly used galvanizing process. The electrogalvanizing is very thin, about 3-5um, the hot plating surface is rough, bright, and there are zinc flowers in severe cases, and the electroplating is smooth and gray (dirty). The galvanized steel plate made by…

The advantages of cold rolled steel coil, come to collect!

ABOUT ZHONGTANG Cold rolled steel coil is a good choice for making metal materials with high strength, wear resistance and high dimensional accuracy, and its cool processing brings several advantages: Cold-rolled steel coils have a higher material hardness than hot-rolled steel coils, so they can maintain their shape more effectively in response to external forces such as hammering, grinding, and bending. In addition, the cold-rolled steel coil has high hardness, uniform density, magnetic stability, low resistivity, and therefore has very good mechanical properties, which can meet the high quality requirements in the field of manufacturing. Due to the ultra-thin…

Introduction to the use of cold rolled steel coil, come and collect!

Cold-rolled steel coil is an important product in steel processing, which is widely used in construction, industry, manufacturing and transportation. It has a variety of uses, as follows: Cold-rolled steel coil can be made into building skeleton, supporting members, roof truss, etc., for the construction of houses, Bridges, tunnels, underground facilities and other buildings. Cold rolled steel coils can be used as parts of machinery parts, appliances, tools and hydraulic systems, and are widely used in various fields of manufacturing. Cold-rolled steel coils can be made into parts of vehicles, rail transit, ships and other transportation vehicles, such as…

What is the difference between cold rolled steel plate and hot rolled steel plate？

Cold-rolled steel plate Cold-rolled steel sheet: using hot-rolled steel coil as raw material, after pickling to remove the oxide, cold continuous rolling, the finished product is rolled hard coil, because of the cold hardening caused by continuous cold deformation, the strength and hardness of the rolled hard coil increase, the toughness and plastic index decline, so the stamping performance will deteriorate, can only be used for simple deformation parts. Rolled hard coil can be used as raw material in hot dip galvanizing plant, because hot dip galvanizing units are equipped with annealing lines. The rolled hard coil weight…

What are the differences between cold rolling and hot rolling processes?

Advantages of hot rolled coil: Advantages: Hot rolled steel coil can destroy the casting structure of the ingot, refine the grain of the steel, eliminate the microstructure defects, make the steel structure dense, improve the mechanical properties. This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic to a certain extent; The bubbles, cracks and looseness formed during the casting of hot rolled steel coils can also be welded under high temperature and pressure. Cold rolled coil disadvantages: 1.After hot rolling, the non-metallic inclusions (mainly sulfides and oxides, and silicates) inside the…

What is hot rolled coil? What is it used for?

Hot rolled coils are steel plates that are heated and rolled by roughing and finishing mills. China is the world’s largest producer, consumer and exporter of hot-rolled coils, with output reaching 232 million tons in 2015. The development of iron and steel industry has effectively supported the steady and rapid development of China’s national economy, and the improvement of hot-rolled coil production and quality has also better met the growing actual needs of China’s construction, machinery manufacturing and other industries. The main uses of hot rolled coil Hot-rolled coil is an important type of steel, mainly reflecting the demand…

The Classification And Use Of Galvanized Coil

Galvanized steel plate is a steel plate with a layer of zinc plated on the surface. Galvanizing is an economical and effective anti-corrosion method that is often used. About half of the world’s zinc production is used in this process galvanized steel plate is to prevent corrosion on the surface of the steel plate to extend its service life, coated with a layer of metal zinc on the surface of the steel plate, this zinc coated steel plate is called galvanized steel plate. According to production and processing methods can be divided into the following categories: ① Hot dip…

What is silicon steel? What is the difference between unoriented silicon steel and oriented silicon steel?

1 What is silicon steel? Silicon steel is also called “electrical steel”, is a very low carbon ferrosilicon soft magnetic alloy. The addition of silicon can not only increase the resistivity and maximum permeability of iron, on the other hand, it can also reduce the core loss (iron loss), coercivity, magnetic aging. It is generally used in the iron cores of various motors and transformers, and is an indispensable soft magnetic alloy in the power, electronics and military industries. 2 Classification of silicon steel (1) According to the production process: can be divided into hot-rolled and cold-rolled silicon steel,…

Introduction of several common color coated roll materials

一、PPGI color coating volume material PPGI color coating, refers to the surface coated with organic coating cold rolled steel plate, common PE, SMP, HDP, PVDF and other coating types. It is characterized by excellent weather resistance, corrosion resistance and decorative properties, and is widely used in construction manufacturing, home appliances and transportation and other fields.
