Rigid Sharp-Razor Casing Scraper

Introduction The HD Sharp-Razorâ?¢ Casing Scraper consists of: a high-strength, one-piece mandrel and is designed to meet the demands of Complex wellbore cleanups. By allowing a higher RPM and weight-on-bit rating than the standard Shape-Razor device. The HD Sharp-Razor Casing Scraper unit is well suited for drilling up cement accessories commonly found inside the liner or casing. Features More effective, robust and safer to use in a ll wellbore-cleanup of casing-scraping operations. Higher RPM and weight-on-bit rating than the standard Shape Razor. 360°coverage, and equal cleaning force at all angles of well inclination. Suitable for severe environment, HTHP-compatible and is not vulnerable to chemical or acid attack. Available with all API and premium drill pipe connections. Application Removes cement sheath, burrs, and pipe scale Pre-completion wellbore clean-up Workovers and sidetracking Abandonment Drilling / milling cement plugs

Introduction SUPER Unique Sharp-Razor Series is a heavy duty wellbore clean-up scraper suitable for all downhole conditions and with robust, high performance features. Run separately or as part of a comprehensive wellbore clean-up, the SUPER Unique Sharp-Razorâ?¢ is designed to effectively remove cement and other debris from the casing wall, through reciprocation. The scraper cage flexes like a spring, to conform to the casing internal surface, to mechanically remove hard debris from the casing. The alloy bronze bearings feature both axial and radial elements to allow extended rotation in harsh environments preventing tool and casing wear. The Heavy Duty version includes an integral string mill. The Standard Duty version comes with a plain external diameter.

Description: Casing Scraper is ideal for the removal of mud, cement, bullets, rust, scale, paraffin, perforation burrs and other obstructions from the inside walls of casing. Maintaining a clean casing I.D. is important when operating drilling, fishing, or wireline tools.

Casing Scraper is ideal for the removal of dirt which may be left over the inside walls of casing, such as solid cement, hard wax, various salt crystals or deposits, perforation burrs, iron oxide residues resulted from rusting, so as to make all down hole tools pass through unblocked. Especially when a small circular clearance is available between the down hole tools and casing inside diameter, the complete scrapping becomes more necessary before further working. At present in the large petroleum well scrapping in the internal wall of casing by use of casing scraper is a necessary step.

Mine scraper scraper as a connection, its abrasion resistance and tensile ability will not only affect their own use, for the normal operation of the entire scraper has an impact, the lofty building rises from the ground, of course, want to have good performance, the mine scraper scraper material choice is about to pay attention to. From the current market situation, 40Cr material scraper scraper is a better choice, to meet the use of coal production needs, in the degree of wear resistance or considerable. Good material also not line, mine blowing machine scraper to durable to start from the machining process, first select the forging scraper is the right choice, relative to the casting quality for scraper is in a class, implemented by every production process, processing equipment of the escort, from the expected product each link strict control. A good mine scraper scraper quality from the details, human and material costs of investment only for the production of good scraper scraper, not a price war, only a quality war, this is the way to survive the development of enterprises. Henan Shuangzhi Machinery specializes in the production and sales of scraper, bolt, dumbbell pin, gear rail, sprocket components and other accessories. Welcome to consult and cooperate with new and old customers!

Sprocket wheel is an important component of sprocket assembly. Sprocket assembly is composed of sprocket wheel, sprocket shaft, bearing, bearing housing, sealing ring, etc. Sprocket material is made of 42CrMo, and its mechanical and other aspects of performance are better than other materials. Sprocket wheel of sprocket assembly is mainly produced by forging and quenching process to improve sprocket wear resistance, of course, there are other processing equipment finishing. The processing requirements of sprocket assembly sprocket wheel shall first ensure that the surface of sprocket wheel forgings of sprocket assembly is free from cracks, interlayers, folds, forgings, slag inclusion, crust and other defects, and check to ensure that there is no crack in the middle of the sprocket body. Secondly, the tempering hardness of the sprocket wheel of the sprocket assembly reaches HRC250-280, and the tooth surface is quenched. The quenching hardness of the tooth surface of the sprocket is HRC50-55, and the hardening layer depth is 10mm, so as to improve its wear resistance and extend the service life of the sprocket assembly. Through to the sprocket chain wheel body component processing, can also see that double of henan for scraping machine sprocket components such as all kinds of machine parts production strictly, made of high quality products, customer satisfaction products, has been a double the execution of the standard, we use good products, in exchange for your trust, if you need a scraper conveyor sprocket, welcome to contact us, double of henan look forward to cooperation with you!

Scraper conveyor sprocket component and the sprocket wheel of the everyday is the same, is through the chain to realize power transmission and run, through its name can be seen that it is in the coal mine fully mechanized working face of scraper conveyor equipment accessories, located in the head, tail, so there are according to different location is called the nose wheel component, the tail sprocket components. So the sprocket assembly of the scraper conveyor can only be used on the scraper conveyor? Isn't. Scraper conveyor and reproduced machine structure is known to all, similar to that of the nose and tail sprocket components for scraper conveyor sprocket component size is the same, the nose sprocket components than the tail sprocket and reproduced machine components, but for the sprocket used component structure are the same, so the scraper conveyor sprocket components can be used in reprint machines is scraper conveyor on the nose of the tail with chain wheel component, the nose chain wheel component and the tail sprocket and reproduced machine components used two sprockets types are different, so most of the time just call, But the scraper conveyer and the transporter sometimes use the same sprocket assembly. Whether it is scraper conveyor sprocket assembly, or transfer machine sprocket assembly, as long as there is sprocket assembly figure number can be accurately implemented sprocket assembly, its name labeling does not have a great impact, so sometimes we do not too complicated name. Henan Shuangzhi Machinery as a scraper parts manufacturer, scraper conveyor sprocket assembly model and specifications are relatively complete, can help you implement the product for processing and production, let you find the right person, give you the right product, we have been working hard, welcome you to consult and cooperation.
