Pipe fitting Full-time Job

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:

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

Introduction

PPR pipe as a common pipeline water supply system is widely used in various construction industries, including residential domestic piping systems, hotels and shopping mall plumbing projects, etc...

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?

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.

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!

Cast Iron Valves Specifications

Cast iron (also known as gray iron) is a type of metal that has been in use for hundreds of years. It is an alloy made from 96%-98% iron, 2%-4% carbon, and small amounts of silicone. It has impressive temperature tolerance, with some cast iron capable of handling temperatures over 2100F (1150C). When it comes to pressure, cast iron's strength depends on its pressure class. The two most common are class 125 and class 250. At less extreme temperatures, class 125 cast iron flange is rated for pressures between 150 and 200 psi. Class 250 cast iron is a bit tougher, with pressure ratings from 300 to 500 psi. These pressures can vary by end type.

Cast iron is strong and will usually go undamaged even after going through intense vibrations. The main drawback of cast iron valves is that they are not very ductile at all. Virtually any bending will cause cast iron to crack and become useless. One great quality of cast iron is that it is not very expensive. As far as metals go, cast iron is usually the most economical option, which makes it a solid alternative for people on a budget.

Ductile Valves Specifications

The second material we're looking at is ductile iron. Ductile iron is a more modern iron alloy that is made with nodule-shaped graphite. This gives the material excellent ductility, so it will not necessarily break when bent. The temperature limit is a bit lower than cast iron, but it is still quite high at 1350F (730C). When it comes to pressure, ductile iron valves also use pressure classes: 150 and 300. At standard outdoor temperatures, class 150 ductile iron keeps a seal up to 250 psi. Class 300 can stand up to pressures as high as 640 psi.

Ductile iron has excellent corrosion resistance, tensile strength, and yield strength. Unlike cast iron, ductile iron does not break when it is bent, so it is more suited for high demand applications. Ductile iron is a strong and reliable material for pipes, fittings, and valves. One drawback is price. Ductile iron is typically more expensive than cast iron due to its more complicated chemical makeup. If your application requires a tougher material, however, you may need to spend a little more.
