The casing is mainly used to support the wellbore during and after drilling to ensure the normal operation of the entire oil well after the drilling process is completed. Different types of casing used in oil production: The surface oil casing is used to protect the well from contamination by shallow water and shallow gas layers and to support the wellhead equipment and maintain the other layers of the casing. Technical casing is used to separate the pressures at different levels so that the drilling fluid can be circulated and the production casing can be protected. In order to install anti-blasting devices, leak-proof devices and tail pipes in wells. Oil reservoir casing drains oil and natural gas from the reservoir beneath the surface and is used to protect the well and stratify the drilling mud. When the oil casing is produced, the outer diameter is usually 114.3 mm to 508 mm. Domestic casing according to SY/T 6194-96 regulations, casing length is not fixed, its range of 8-13m...

Hot forging means forging blank metal above the recrystallization temperature carried out.

The total zinc coating condition applied depends mainly on the mass and thickness of the galvanized steel tubing. Usually the surface of the galvanized layer should be complete and uniform and with a standard thickness. The evaluation of the appearance quality of the galvanized layer is very important. The following listed the common surface conditions of the galvanizing layer for   galvanized steel pipe . 1. Gray and dark-gray cobwebbing The chemical elements of the steel tube such as C, Si, P and Mn will cause Fe-Zn alloy reaction with the increase of the content, produced zinc-iron alloy layer on the coating surface, especially with Si increased, which accelerate the reaction of iron-zinc melt mutually, formed on the surface of gray even the black net. The black coating layer is thicker than the bright coating, the corrosion protection and prevention ability completely inferior to the bright coating, but will be more resistant to corrosion but may not pretty sensually. Ho...

The API 5CT standard covers seamless and welded casing and tubing pipes for oil and gas transportation.   Casing pipes   are available in the following materials: H-40, J-55, K-55, N-80, L-80, C-90,T-95 ,P-110, Q-125. Depending on the different condition and depth of the well, we use the different steel grades. The casing is required anti-corrosion under the corrosive environment. In the case of complex geological conditions, the casing has to be resistant to collapse. Most casing steel grades have the same chemical composition. What makes grade different is the heat treatment applied. Casing grades mainly differ in their yield strength, tensile strength, and hardness. According to API 5CT, there are four groups of products to API SPEC 5CT is applicable include the following grades of pipe: Group 1: Grades H, J, K,M, N and R; Group 2: Grades C, L and T; Group 3: Grade P; Group 4: Grade Q. Additional tests required by API 5CT for certain groups of casing make s...

A process for producing hot rolled strips with a thickness of 1.2-8 mm on a hot strip mill. The strip width of 600mm is referred to as narrow strip steel; the width of strip steel is more than 600mm. The first strip hot rolling mill was put into operation in the United States in 1905, producing a 200 mm wide strip. The strip hot rolling mill has superior technical and economic indicators and it has developed rapidly. In industrialized countries, before 1950, the output of hot-rolled wide-band steel accounted for about 25% of the total steel output, and it had reached about 50% in the 1970s. The raw material of the hot strip is continuously cast slab or green rolled slab, thickness 130-300mm. After the slab is heated in a heating furnace, it is sent to a rolling mill and rolled into a strip of 1.00-25.4 mm in thickness and rolled into coils. Rolled steel grades are plain carbon steel, low alloy steel, stainless steel and silicon steel. Its main purpose is to make cold-rolled stri...

1. Delivery status It refers to the state of final plastic deformation or final heat treatment of the delivered product. The hot-rolled or cold drawn (rolled) state or manufacturing state generally delivered without heat treatment; the heat-treated state after heat treatment delivery, or the normalizing, tempering, solid solution, annealing according to the type of heat treatment status. When ordering, the delivery status must be specified in the contract. Quenching: The process of rapid cooling after heating above the transformation point temperature. Improve the hardness of the material, but reduce the toughness. Normalizing: After heating above the transformation temperature, cool normally (in air). Annealing: After heating to above the transformation point temperature, slowly cool. Eliminates quenching effects, eliminates stress, and homogenizes components. Tempering: After quenching, heat to a certain temperature (below the quenching temperature), keep warm, and then ...

As one of the most widely used materials for engineering project, steel can give customers eminent strength, toughness and durability. So does for the ramification of steel pipe from   seamless steel pipe   to welded steel pipe like galvanized steel pipe, we can see the large usage range nowadays. Steel pipe, with a versatile, cost effective solution for a broad range of applications, has the categories including: Construction and architecture usage: for this, we can have SSAW steel pipe, LSAW steel pipe and even seamless steel pipe for customers. Water/sewer plumbing: generally speaking, we would like to choose SSAW steel pipe, ERW steel pipe for water transportation. Pipeline systems: This depends one the function of the pipeline system. We would adopt seamless steel pipe for the oil and gas, and welded steel pipe for water and so on. Gas and fluid transfer lines: Typically, we would depend on seamless steel pipe most time for the gas and fluid transfer lines. ...

As we all know, each step during steel pipe(from   seamless steel pipe   to ERW steel pipe as well as galvanized steel pipe) production would have decisive impact on high quality of the steel pipe. Today, our main topic is production control: First of all, the controlling of steel pipe’s gap. Large or not would have main effect for the quality of steel pipe. Poor welding would come from the large weld control as the welds are not fused or cracked. Due to the heat is too large, the weld control is too small, this would lead to weld burns. What’s more, high-frequency induction coil position control. For position, it is necessary to make the induction coil on the same center line with the steel pipe. And for the distance, it is important to make sure they are as close as possible for the front end of the induction ring and the center line of the pressing roller to the steel pipe, thus, it would reduce the strength of the weld.

Process of cold drawn   seamless steel pipe round tube → heating → perforation → Heading → annealing → pickling → oiled (copper) → multi-pass cold drawn (cold rolled) → blank tube → heat treatment → straightening →hydrostatic testing (testing) → mark → storage. The general cold strip mills, volume should go through continuous annealing (CAPL unit) to eliminate cold hardening and rolling stress, or batch annealing reach the mechanical properties of the corresponding standard specifies. Cold rolled steel surface quality, appearance, dimensional accuracy better than hot-rolled plate, and right-rolled thin product thickness is about 0.18mm, so the majority of users favor. Cold rolled steel coil substrate products deep processing of high value-added products. Such as electro-galvanized, hot dip galvanized, electro-galvanized fingerprint resistant, painted steel roll damping composite steel, PVC laminating steel plates, etc., so that the excellent quality of these products has a...
