Designing application pressure for chemical pipelines is a critical aspect that ensures the safe and efficient transport of chemical substances. Several factors must be considered to determine the appropriate pressure requirements for a given application. Here are the key factors that influence the design of application pressure for chemical pipelines:
The viscosity and density of the chemical being transported directly impact the pressure required to maintain a consistent flow rate. Higher viscosity substances require greater pressure to overcome resistance within the pipeline.
The chemical reactivity and stability of the substance influence the choice of materials and design parameters. Reactive chemicals may require additional considerations to prevent pressure-related incidents.
The desired flow rate of the chemical substance is a primary determinant of the application pressure. Higher flow rates necessitate increased pressure to achieve the desired throughput.
The diameter of the pipeline affects the pressure needed to maintain the desired flow rate. Larger diameters may require lower pressure, while smaller diameters may necessitate higher pressure.
Friction between the chemical substance and the internal surface of the pipeline results in pressure loss. This friction loss must be accounted for in the design to ensure adequate pressure is maintained throughout the pipeline.
The length of the pipeline contributes to friction loss, with longer pipelines experiencing greater pressure drop. This factor must be considered when determining the initial application pressure.
The tensile strength of the pipeline material influences its ability to withstand internal pressure. Materials must be selected based on their pressure rating and compatibility with the chemical substance.
Corrosion resistance is crucial to prevent material degradation and maintain structural integrity under pressure. Materials should be chosen to withstand the specific chemical environment.
External environmental conditions, such as ambient temperature and atmospheric pressure, can impact the internal pressure of the pipeline. These factors must be considered to ensure the pipeline’s performance.
Incorporating safety margins into the design accounts for potential fluctuations in pressure due to environmental changes or operational variations, preventing pipeline failure.
The design of application pressure for chemical pipelines is influenced by a combination of chemical properties, flow rate requirements, friction loss, material selection, and environmental conditions. By carefully considering these factors, engineers can ensure the safe and efficient transport of chemical substances, minimizing risks and maintaining the integrity of the pipeline.
ERW BLACK Pipes. Electric Resistance Welded (ERW) Pipes are manufactured from Hot Rolled Coils / Slits. All the incoming coils are verified based on the test certificate received from steel mill for their chemistry and mechanical properties. ERW pipe is cold-formed into a cylindrical shape, not hot-formed.
Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length. In Seamless pipe, there are no welding or joints and is manufactured from solid round billets.
The 3 elements of pipe dimension Dimension Standards of carbon and stainless steel pipe (ASME B36.10M & B36.19M) Pipe Size Schedule (Schedule 40 & 80 steel pipe means) Means of Nominal Pipe Size (NPS) and Nominal Diameter (DN) Steel Pipe Dimension Chart (Size chart) Pipe Weight Class Schedule (WGT)
Seamless pipes are manufactured using a piercing process, where a solid billet is heated and pierced to form a hollow tube. Welded pipes, on the other hand, are formed by joining two edges of steel plates or coils using various welding techniques.
Carbon steel pipe is highly resistant to shock and vibration which making it ideal to transport water, oil & gas and other fluids under roadways. Dimensions Size: 1/8″ to 48″ / DN6 to DN1200 Thickness: Sch 20, STD, 40, XS, 80, 120, 160, XXS Type: Seamless or welded pipe Surface: Primer, Anti rust oil, FBE, 2PE, 3LPE Coated Material: ASTM A106B, A53, API 5L B, X42, X46, X52, X56, X60, X65, X70 Service: Cutting, Beveling, Threading, Grooving, Coating, Galvanizing
The ASTM International specifications for steel tubes list standard requirements for boiler and super heater tubes, general service tubes, steel tubes in refinery service, heat exchanger and condenser tubes, mechanical and structural tubing.
Casing pup joints are essential components in the construction and operation of oil and gas wells. They allow for precise adjustment of the casing string length, ensuring proper placement of downhole equipment and alignment with wellhead components. Selecting the appropriate pup joints based on diameter, material grade, and thread type is crucial for maintaining well integrity, safety, and efficient operation.
Couplings are short lengths of pipe used to connect 2 joints of tubing or casing. They come with painted colour codes on their external surface to indicate their grades. Couplings are manufactured according to API 5CT and 5B specifications.
Drill pipe is a steel pipe with thread at the end, which is used to connect the surface equipment of the drilling rig to the drilling and grinding equipment or the bottom hole equipment at the bottom of the drilling. Drill pipe can be divided into three categories: kelly, drill pipe and heavy drill pipe. Drill collar is located at the bottom of the drill string and is the main component of the lower drill tool assembly. Its main feature is that the wall thickness is larger, and it has greater gravity and rigidity. In order to facilitate tripping work, elevator grooves and slip grooves can be processed on the outer surface of the inner thread of the drill collar. Drill collars are generally divided into three types: spiral drill collars, non-magnetic drill collars, and integral drill collars.
Slotted pipe are used for oil and gas wells. Steel casing pipes and tubing are applied to furnishing and installing cased tunnels, where they indicate to pass other utilities or obstructions without open excavation. Steel casing pipes and tube have smooth wall and a minimum yield strength of 35,000 psi. Corrosion-proofing water-based paint is applied on the outside pipe surface to protect against atmospheric corrosion during transportation and storage.
Petroleum special pipes are mainly used for drilling oil and gas wells and oil and gas transportation. Oil casing is mainly used to support the wellbore during driling and after completion to ensure the normal operation of the wholewell, Oil casing is the lifeline to maintain oil well operation. Because of the different aeolodical conditions.the stress state of underground is complex, and the comprehensive action of tension, compression, bending and torsion stresses acts on the pipe body, which puts forward higher requirements for the quality of casing itself.

WHAT IS PIPE PREFABRICATION? Pipe prefabrication is manufacturing pieces of pipelines in a factory instead at the construction site. This enables utilization of better tools and working conditions. This results in higher productivity and better quality. It also reduces the lead time at the construction site.
