Three main types of hollow section tube

February 12, 2019 by sara052807  

Weve listed about five categories of hollow section tube in previous essay. Talking about ERW or seamless steel pipe, hollow pipeline can be divided in three main types for its structure.

 

They are circular tube, square tube and rectangular tube. You can get the details from the picture below. Of course, for the standard and grade of this tube, we may have four main categories. They are GB, EN, ASTM, and JIS. We are glad to discuss with you for details with your demands for the type you need. 

Hollow section tube offering from threeway

January 4, 2019 by sara052807  

As steel pipe supplier with more than 20 years, threeway has listed a main categories for hollow section tube except the general seamless steel pipe and weld type. Today, we shall list our hollow section tube offering here.

 

A hollow section tube has a hollow tubular cross section, made by structural steel per code.

Scaffolding tube: Scaffolding is a temporary structure used to support people and material in the construction or repair of buildings and other large structures. Material Storage Racks, Pallets, Hydraulic Platforms, Trusses, Columns, Purlins, Greenhouse, Stands Towers, Agricultural Equipment.

Rectangular tube: This steel pipe will be used in fluid transportation, construction structure, etc.

Anti-corrosion steel pipe: Anti-corrosion steel pipe is processed through the preservation process, which can effectively prevent or slow down the process in the transport and use of chemical and electro-chemical corrosion reaction of steel pipe.

Square steel tubes: These tubes have square shape. However, they can also be availed in other shapes, like hexagonal, rectangular, triangular, or round. They are used in cable bridge structures, airport structure, hall structure, ornamental pipes, etc.

Galvanized steel pipe: They are used extensively in applications, such as boiler pipe, scaffolding pipe, furniture, fence/door pipe, structure pipe.

Choosing steel pipe from aesthetic perspective

January 2, 2019 by sara052807  

It is not a joke when you see the title here. We will consider the appearance when we choose boyfriend or girlfriend, so does for the customers. They will choose seamless steel pipe or welded pipe like ERW steel pipe from aesthetic perspective.

 

How? And whats the standard for this choice? Here are the answers.

If you are considering wholesale pipelines which are exposed or featured in some way, most of customers would choose seamless steel pipe directly. Its clean and finished look would be the determine factor.

If you just want to purchase pipeline which is remain permanently hidden in the walls of a building or underground, there is no need to pay high price to get seamless type, and welded pipes would obviously be perfectly acceptable. 

See you in 2019 with our steel pipe business

December 29, 2018 by sara052807  

Today would be our last work day in 2018 and we shall see you in next year of 2019. Hereby, we wish all of you a happy New Years Day. Our business on ERW steel pipe and other tubes shall go on in next year.

 

As steel pipe's supplier for more than 25 years, we are devoted to provide professional one-stop procurement service for customers with excellent quality, competitive price, convenient transportation and timely delivery. We shall follow the market trend and quality control to make sure the advanced technology used among our steel pipes production. Thus, we can supply our customers with high quality steel pipes all the time. 

Is seamless steel pipe better choice than welded tube?

December 28, 2018 by sara052807  

The answer would be uncertain. No matter the option for seamless steel pipe or welded type, the choice will rely on projects application, because different specs and grades of steel pipe have unique characteristics.

 

Except price and other factors affecting the choice of pipelines, we will talk about the choice just from the application.

For welded tube, it would be popular when used for moving things like water and other low pressure products. If there is a water transportation system in a yard sprinkling, we will adopt this. Of course, structures like yard fences and more critical usage are also nice for using of welded pipe.

For seamless steel pipe, due to its special durable and reliable quality with the feature of no seam, seamless steel pipes might then be necessary for machinery, as the stronger steel lasts longer and is less susceptible to failure.  

Barren village needs the help of steel pipe

December 27, 2018 by sara052807  

Its a barren village. Its a place without thoughts. I walked out of the hut, watching the water beside the house run down the tangled weeds into the valley, clear water, muddy water. Just once, if there is SSAW steel pipe for water transmission, it would be a wonderful place for living.

 

Why are you staring at the water everyday? My litter sister asked me.

Dont you think its unbearable? I asked her seriously.

Whats unbearable? the water?

I nodded, When you see water mixed with straw ashes, you know the family is washing their hair; when you see the oil water, you find they are eating their food; when you see dirty water, you even know someone is doing his business. Isnt it unbearable?

Then what can we do ? she asked with her usual joking expression.

steel pipe, the pipe! I have said it for many times! With it, we shall convenient in all aspects if we have transmission problem. I said loudly. At this time, we finally figure out that even for barren village, we need the help of steel pipe. 

Ten principles for good design of steel pipe

December 26, 2018 by sara052807  

With more than 20 years experience on producing steel pipe, ranging from seamless steel pipe to welded type, our manufacturer would like to talk something about the birth of high quality steel pipeline.

 

There are ten principles for high quality for steel tubes.

Good design is innovative. Advanced technology would bring new technology for producing of steel pipes, thus, we should keep pace with the age.

Good design makes a product useful. Combined with new skill, we will provide customers more useful steel tubes for various engineering projects.

Good design is aesthetic. Except usage, we will pay attention to look appearance too.

Good design makes a product understandable. Products come from design, a good design would lead to nice users experience.

Good design is honest. With honest attitude, we will supply high quality pipelines for customers.

Good design is unobtrusive.

Good design is long-lasting. With quality guaranteed, we will make the life of steel pipes longer than before.

Good design is thorough down to the last detail.

Good design is environmentally friendly. Considering environment, environment would give us good feedback too.

And of course, good design is as little design as possible.

Difference on pipe and tube diameter

December 25, 2018 by sara052807  

Generally speaking, pipe and tube would be similar at first sight. Whether you need ERW steel pipe or other types, you need to figure out the difference between them before your purchase.

 

Today, we'd like to share the difference on pipe and tube's diameter.

Different co-reference for diameter:

Pipe's diameter means the nominal diameter and it's not actual. The actual physical outside diameter is larger than the nominal OD.

Tube's diameter refers to the actual outside diameter. So its actual physical OD is same with the nominal one.

Different accommodate application with size:

Pipe's accommodate large application with sized that range from a half-inch to several feet.

Tube's size is generally used in applications that require smaller diameters. 

Steel pipe corrosion triggered by contact with iron or carbon particles

December 24, 2018 by sara052807  

Once we decide to choose steel pipe for our engineering project, we should make sure the protection work from all aspects. And for seamless steel pipe, even for seamless stainless type, we still need to focus on the corrosion triggered by contact with iron or carbon particles.

 

Stainless steel corrosion can also be triggered by contacting with iron or carbon steel particles. Trace particles coming from iron or carbon steel have impact on stainless steel pipes surfaces, like rust would be one of the types. If we dont take care of this rust situation, the rust spots would grow, and it may compromise the chromium oxide surface and, in the worst cases, it can evolve into pitting like localized corrosion. Contamination is common when stainless steel is subject to sparks from nearby welding, cutting, drilling, or grinding of carbon steel. So attention would be all the time once we adopt the steel pipe in our daily work.
