In generale, il trattamento superficiale delle piastre di acciaio strutturale è necessario per aumentarne l'anticorrosione e la durata. La qualità del trattamento superficiale influisce direttamente sull'adesione del rivestimento al substrato del pezzo rivestito e sulla resistenza alla corrosione del materiale. Olio, grasso, polvere e altri contaminanti causano la caduta della pellicola di vernice o [...]
Il tubo di linea in acciaio API 5L X42 è generalmente utilizzato per il trasporto di petrolio e gas in linee di trasmissione, linee principali di distribuzione e sistemi di condutture offshore. Zhonghai fornisce gradi API 5L saldati e senza saldatura attraverso X 70 per applicazioni ad alta pressione, tutti i prodotti di linea in acciaio API 5L X42 che stiamo fornendo possono raggiungere lo standard internazionale [...]
Wldsteel produces welded steel line pipe, both spiralweld and rolled and welded, in lengths from 30’ to 60’ and wall thicknesses from .250 inches to 2.0 inches. These line pipes, often used to transfer liquid and air, meet the following standards: AWWA C200, ASTM 139, ASTM 134, and ASTM 135. Steel pipe has many advantages […]
The condenser is important auxiliary equipment in the thermal generator set. The condenser is generally composed of neck, casing, water chamber, tube bundle, tube plate, support rod, steam baffle, air cooling area, hot well and other parts, which is the key equipment to determine and affect the load and thermal efficiency of a steam turbine. The heat […]
In the last article, we introduced what is caustic cracking, the type of caustic cracking and the harm of caustic cracking. Today here we will continue to describe how to prevent caustic cracking corrosion. Choosing the carbon steel material Carbon steel equipment can be used to hold caustic soda at room temperature, considering the terms of […]
Caustic Cracking, also known as caustic embrittlement, is the metals cracking in alkaline solutions due to the combined action of tensile stress and corrosive media, is a type of SCC. The cause cracking of pressure boiler mainly occurs in the parts where steam is repeatedly evaporated and condensed or in contact with caustic soda, which may be carbon steel, low […]
Epoxy coal tar is a kind of ] corrosion prevention coatings with excellent impact resistance and water resistance, consist by the modified epoxy resin, polyamide resin, coal tar, fillers and additives, offering excellent water resistance, microbial corrosion resistance, good adhesion, toughness, moisture resistant. It can prevent all kinds of ion etching, has been widely used in steel used […]
Steel pipe pile foundation has the characteristics of quick construction, safety and highly mechanized operation, and is often widely used in large offshore bridges, substructures of ports and wharves, temporary platforms and trestles, etc. Compared with reinforced concrete foundation, steel tube pile foundation has the following advantages: Lightweight, high strength, convenient loading and transportation; High bearing capacity. […]
In the offshore and inland alluvial plain region, the thickness of 50 ~ 60 m soft soil layer of the upper load is big and can not directly as a bearing layer, the low compression bearing layer is always deep, where usually use the general structure of steel pile with a pile hammer producing a large impact on it. Steel pipe pile reinforcing […]
The strength of steel refers to the deformation and fracture performance of metal materials under the action of external force, which generally includes tensile strength, bending strength and compressive strength. The more resistant steel is to external forces, the stronger the steel will be. So how can we improve the strength of steel? Solution Strengthening The […]
