Pipe Fittings: Various aspects of Using them
Pipe fitting is meant for plumbing and piping system which is used in commercial and industrial industries. Fitting helps pipes to be joined properly so as to close them wherever required. These fittings can be found in market in different sizes and shapes. Besides, they can demand more time and can be expensive. They use distinct tools and materials to join and install. If you are working with plumbing or piping, then it is very essential to use pipe fitting.
There is an assortment of fitting available in market. All pipes require a unique type of fitting but there are certain common features which are shared by all type of pipe fittings. Wherever materials for plumbing are sold, you can easily and conveniently find pipe fittings.
How to connect pipe fittings with the pipe?
You can find pipe fittings in two varieties, female fittings and male fittings. The female threads are there on the inner side in a threaded pipe fitting. Street fittings are those having a male and a female end. Tube and pipes can be connected using pipe fittings in two ways:
Threaded pipes are twisted together for joining them. In most cases, metal pipes have threaded fittings.
Sleeves are used with slip fit pipes and they slip into each other. Generally, plastic pipes are slip fit but they can also be threaded.
What criteria should be considered in selection of pipe fitting?
There are certain factors to be considered while selecting pipe fitting:
Types of connection
While you are embarking on the journey of buying pipe fittings, you must keep in mind that there are two types of connectors. It may be that one end is female threaded while the other female slip. Or it may be that one end is male slip while the other end is threaded when you are talking about plastic fittings. Besides, they are also available with matching ends, which can house all requirements.
It is a common phenomenon that the pipe fitting material should be same as the material used in the pipe. Nevertheless, at times, certain materials can also be used in pipes of made of any material.
Checking it for flow
In comparison to the rest of the pipe fitting, the end of the fitting should be made a bit larger in order to keep it flowing consistently. It will help in accommodation of the connection without causing damage to the pipe’s inner diameter.
In addition to the material of the pipe, the type of fitting should also be taken care of, which include threaded or slip fitting and male or female fit.
Pipe fittings size is measured in different ways at the outside and inside end. The outside edge of the pipe fittings are measured in cases of male threaded fittings while in case of female threaded fittings, size is measure from inside edge of the inlet.
Different pipes are designed to carry different fluids like gases, liquid or chemicals. In accordance to the purpose of the pipe, there are varied pipe fitting designs available.
Pipe fittings are also available in different thickness same as pipes.
Codes and standards
Various organizations have set different standards in accordance of which pipe fittings are graded. Some of those standards associated with pipe fittings are ASTM, BSP, and ASME.
What are the main uses of ppr pipe fittings?
Ppr pipe fittings are the most commonly used materials in home decoration, and their capabilities are not small, such as water supply, hot water pipe systems, heating pipe systems and air conditioning pipes. Engineering hot water is generally directly related to the use of ppr pipe fittings, which are more stable, safe, easy to install, and cost-effective. Engineering hot water ppr pipe fittings can also be hidden. When the concealed pipe penetrates the wall, in order to ensure the safety, service life and maintenance of the pipe, a metal sleeve can be installed to ensure the installation of ppr pipe fittings.
In installation engineering, ppr pipe fittings have the advantage of hot-melt connection. Pipes and pipe fittings are welded by temperature heating, so that water is not easy to leak, but the heating temperature and time need to be accurate and not too long. If the temperature is too high for too long, the pipes and fittings will be damaged by hot melt. If the time is too short and the temperature is too low, the pipes and fittings will be unstable and easy to burst.
Nowadays, ppr pipe fittings are becoming more and more popular in society, involving water supply, sewage, irrigation, gas transmission and other uses. Due to its own advantages and characteristics, it can stand out in the pipeline market and occupy a very important position.
PPR is a random copolymer polypropylene. In winter, the flexibility of PPR water pipes will decrease, while the rigidity will increase and flatten. If the pipe is impacted by an external force, the surface of the pipe will crack more seriously.
Therefore, ppr pipe fittings manufacturers suggest that when we use or install ppr pipe fittings in winter, we need to be more careful to prevent pipe collisions and littering. Caring for the pipeline means caring for our own water consumption.
Get to Know About PPR Pipe
So how much do you know the PPR pipe you are using? How do you select the best PPR pipe or fitting for your project? Through this article, let get to know about PPR pipe!
What's PPR pipe?
PPR pipes are a new type of environmentally friendly pipes, which also represent the development direction of drainage pipes in the future.
So what is PPR means? PPR is a random co-polymer polypropylene, which is formed by random co-polymerization of propensity monomer and a small amount of ethylene monomer under the action of heat, pressure and catalyst.
The ethylene monomer is randomly distributed in the long chain of propensity, and the ethylene monomer is generally controlled between 3-5%. The ethylene content and the polymerization method of ethylene and propensity determine its cold brittleness.
Therefore, in winter, the flexibility of the PPR pipe will decrease, while rigidity will increase and flatten. If the pipe is impacted by an external force, the surface of the pipe will crack more seriously.

Thermoplastic composite pipe on the rise in the deep sea
Visit the news pages of the Airborne Oil & Gas (AOG, IJmuiden, Netherlands) and Magma Global Ltd. (Portsmouth, U.K.) websites and you’ll come away with the impression that 2018 was a watershed year for these two leading manufacturers of thermoplastic composite pipe (TCP) for deep-sea applications. But don’t be surprised if 2019 news about this burgeoning market for composites eclipses that of the preceding year.
A few notable achievements of 2018 for AOG: In June, the company commenced a qualification program for carbon fiber/polyvinylidene difluoride (PVDF) risers (pipes connecting subsea production systems and surface production vessels) for a major operator in South America. AOG worked in collaboration with Subsea 7 (Luxembourg), a major offshore installation contractor, on this project. In August, after an extensive five-year qualification program followed by the world’s first pilot installation on hydrocarbon (full well bore) service of a glass fiber/high-density polyethylene (HDPE) flowline (pipe that connects the well head to further processing equipment), Petronas (Kuala Lumpur, Malaysia) recognized AOG’s TCP flowline as having achieved technology readiness level 6 (beta prototype verification). “And we expect to reach TRL 7 [pilot system demonstration] in 2019,” reports Martin Van Onna, AOG CCO. Along with these successful qualifications and pilot programs, AOG reports a growing commercial track record, especially with its glass fiber/HDPE TCP.
As for Magma, 2018 was equally eventful. In March, Tullow Ghana awarded a contract to Magma for a 2.5-kilometer flowline for its development of Tweneboa, Enyenra, Ntomme (TEN) offshore fields. In May, working with Ocyan (Rio de Janeiro, Brazil), an offshore services company, Magma completed and received third-party validation of a Composite Multi-Bore Hybrid Riser (CMHR) design that employs Magma’s carbon fiber/polyetheretherketone (PEEK) m-pipe. Magma and Ocyan are bidding the CMHR for deep-water developments in Brazil. Magma announced in August that a joint initiative with Equinor (Stavanger, Norway) had secured £10.5 million in funding from Innovate UK, a government funding source, to qualify an all-Magma solution for jumpers (pipes that connect flowlines and/or subsea facilities). Finally, in November, the Energy Institute (London, U.K.) bestowed its 2018 Award for Innovation to Magma for its m-pipe, citing the pipe’s ability to solve the challenges of oil and gas production in deepwater reserves, as well as its ability to be reused.
Valves - Choosing Between Ductile and Cast Iron
Customers from all kinds of industries need valves of all varieties for their high-demand processes. Valves are available in a huge number of materials for any application imaginable. A few of these materials are PVC, carbon steel, stainless steel, cast iron, and ductile iron. In this post we will focus on two of those materials: ductile iron and cast iron. The argument of "ductile vs. cast iron valves" has been going on for decades, as not everyone knows the differences.
Luckily, comparing valves made of ductile iron and cast iron is simple, as these materials have just a few major differences. We will outline properties of both materials and then go through the pros and cons of each. By the end of this blog post, you will be an iron expert!
