Pipeline accessories include constituent parts used to control the movement and distribution of fluids and gases through pipelines. Pipeline fittings are mostly made of steel, plastic, or copper and serve different operations, from joining two pipes to redirecting fluid flow in another direction. Common types of pipeline accessories include:
Valves control fluid and gas flow through pipelines. Some common types of valves include:
Gate valves
Gate valves are used where there is a need for complete flow restriction or pipeline closure. Gate valves are made with either a wedge or a circular-shaped gate, which, when moved, either opens up the entire pipeline cross-section or entirely closes it.
Globe valves
Globe valves are often used for flow isolation, although not efficient as a gate valve. They have a spherical body with a movable disk-shaped element inside that, when it twists, either blocks or allows some amount of fluid flow through the pipe.
Ball valves
Ball valves are very effective for quick on-off control of fluid flow. A ball with a bore hole through it is the main closing and opening mechanism of a ball valve. When turned parallel to the pipeline, the hole in the ball allows fluid to flow through. When turned perpendicular, the solid part of the ball blocks flow.
Butterfly valves
Butterfly valves are used for isolation and throttling. They have a disk-shaped closing mechanism which, when turned perpendicular to the pipeline flow, blocks it. Butterfly valves are lightweight and quick to operate compared to globe and gate valves.
Check valves
Check valves prevent backflow in pipelines. They automatically block fluid from reversing direction, protecting equipment and system integrity. Some types of check valves are:
Single check valve: A single check valve has just one opening through which fluid can flow in one direction only. It experiences pressure from below. Back pressure causes the valve to close.
Dual check valve: A dual check valve has two openings and two discs or balls that work together. This allows fluid to flow in a system or pipeline with check valves between them. Any backflow is blocked by one valve opening or by closing both valves.
Pipe clamps are used to support attached pipes to a surface. They usually transfer the weight and load a pipe carries to the surface beneath so that the pipe doesn't sag or bend permanently.
Elbows are hosing fittings that change the direction of the pipe by a specific angle, usually 45° or 90°. They're used to redirect the pipeline, transferring the fluid to the desired location.
Expansion joints absorb thermal expansion within piping systems. As pipes heat up, they expand. Expansion joints allow some flexibility in the system to accommodate this expansion without causing stress, bending, or rupture. They are critical in high-temperature pipeline systems.
End caps are used to close off the end of a pipe. They are essentially a cap that covers the terminal edge of a pipeline to block fluid from flowing out the end. This is useful for lines that don't always need fluid to flow through or to prevent debris from clogging the pipe when not in use.
Pipeline accessories are important for efficient operations in many industries, including construction, automotive, marine, and HVAC systems, among others. The following kinds of pipeline hardware can be got from wholesale pipeline accessories suppliers.
Since most of these accessories are added to or replace defective parts in an already existing pipeline system, it is very important that the new accessories being bought are compatible with the material and dimension of the current pipe. Also, ensure that the fittings are compatible with the fluid to be conveyed to avoid corrosion and contamination.
Pipeline hardware is made from different materials, with each having its own advantages. Stainless steel fittings offer strength, durability, and corrosion resistance. Copper has excellent thermal conductivity properties but is weaker than steel. PVC pipe clamps are lightweight and corrosion resistant. Among others, aluminium.
Buyers need to consider the following questions: What is the operating pressure and temperature the pipeline will carry? Will the accessory be exposed to hostile chemicals? In what orientation will the fitting be installed? What is the current diameter size of the accessories that need replacing? Answering these questions will help buyers to a large extent in making the right purchase decisions.
It is important buyers check if the pipeline hardware conforms to relevant industry standards and certifications, such as ISO, API, or ASME. This ensures they meet minimum performance and safety requirements. Buyers shouldn't hesitate to ask their suppliers to provide documentation as it plays a very important role in quality assurance.
To avoid running over budget, buyers should always develop a budget before heading out to search for pipeline hardware. Remember that purchasing a cheap item might lead to higher maintenance costs in the future, and expensive ones don't always mean they are of good quality. Carefully weigh the benefits of each before making a decision.
The following strategies can be employed to ensure that pipeline hardware lasts as long as possible.
Developing a schedule inspection routine is an effective way to catch minor faults before they escalate into big problems. While doing this, look out for visible signs such as rust, cracks, leaks, or corrosion. Also, pay close attention to the operating pressure and temperature of the accessories and compare them to the manufacturer's recommendations.
Using hostile cleaning agents could damage the internal and external surfaces of pipeline accessories, so it's important to use only those recommended by the manufacturers. When washing, ensure all debris and deposits are cleared. This will prevent corrosion, facilitate efficient operation, and improve the items' esthetic value.
Lubricate all moving parts and joints, such as pipe clamps and valves, to ensure they don't rust and reduce friction. However, be sure to use the right kind of lubricant and follow the proper application technique as stated by the manufacturer. This will ensure moving parts have smooth operations, which will reduce their rate of wear.
Pay attention to temperature, pressure, and fluid types to avoid exceeding the manufacturer-set limits. Doing this will prevent valve and pump fitting failure and other pipeline accessory manufacturers from experiencing high operational costs. Educating employees on these limits will reduce the likelihood of this happening.
Pipeline accessory hardware is one of the easiest industries to work in because repairs don't necessarily mean they have to be replaced. Repairing a damaged valve or clamp instead of replacing it saves time, resources, and effort. So, whenever a fault is detected, fix it promptly to prevent it from affecting other parts.
There are several benefits of having pipeline hardware. Some of them include:
Pipeline accessories facilitate the smooth and efficient movement of liquids and gases through the system. For example, a valve controls flow, elbow fittings help pipelines to change direction, and a pipe clamp secures the hose. All these hardware improve fluid transport efficiency and speed.
Pipeline accessories such as valves and fittings are designed to effectively seal the pipe to prevent leaking. This helps minimize the loss of the conveyed substance to save cost and enhance safety by reducing the chances of explosion and fire and preventing hazardous chemicals from escaping into the surrounding environment.
Expanding a system to accommodate an extra need, change, or addition will require a lot of work. But with the right accessories, such as expansion joints and fittings, a little adjustment will make a pipeline system flexible and capable of overcoming virtually qualquer challenge.
Using the right material and industrial-standard hose accessories will go a long way in ensuring the longevity of the pipeline. These accessories reinforce the structural integrity of the system and protect it from stress, pressure, and environmental factors. This added protection translates to improved durability.
Improper installation and use of the wrong hardware are the two main causes of pipeline explosion and fire. But with the right pipeline accessories in place, such as safety valves and clamps, a more secured environment will be attained both for the maintenance crew and everyone else that interacts with the pipeline system.
Pipeline accessories, such as check valves, arenova hose clamps, and elbow fittings, work together to minimize leaks and repair costs. Besides, they allow the system to run optimally without having to undergo frequent maintenance, saving crumpled currency. More so, since these accessories are durable, they are cost effective in the long run.
A1. The most common hose clamp sizes are 300 series stainless steel, 400 series stainless steel, and 200 series/adjustable bronze.
A2. Because of thermal variations, tension, soil settlement, and other pipeline stresses, expansion joints are a must have for every pipeline system that will be exposed to such conditions.
A3. An end cap is used to close off and shut down pipes with the end of which fluid can flow. It's the perfect solution for keeping the pipe internally safe when not in operation.
A4. Copper is not only corrosion resistant but also has superior thermal properties like heat dissipation and durability that make it potential hose clamp material.
A5. Although corrosion-resistant metals and alloys are a good material for manufacturing fittings, they cause galvanic corrosion when dissimilar metals come in contact with each other in the same environment.
