Polyethylene welding fittings Pars Ethylene Kish

The quality of polyethylene welding joints directly depends on the operator's ability, equipment quality and supervision, which is responsible for the relevant standards. This process must be observed from beginning to end to eventually achieve the desired quality product. Before starting the process of polyethylene welding fittings, all parameters should be taken into account (the parameters are explained below) and the operator must be educated and have a certificate of fusion welding.

things to consider before starting the welding process of polyethylene fittings:

• The welding environment should be more than 5 degrees Celsius and should be done in a protected space of rainy and cold air.
• In order to prevent air circulation and rapid cooling, the end of the pipes must be closed.
• The welding area should be clean and without damage.

Polyethylene fitting welding method

In good welding polyethylene joints, the welded area provides at least the same strength with the main tube. To have a application for welding, welding pressure, temperature parameters and welding time must be carefully adjusted.

Preparation of Polyethylene Welding Fittings

Before starting the welding process, temperature polyethylene joints must be controlled in the joint welding machine, which is performed by an infrared thermometer. The heater plate should be removed at least 10 minutes after reaching the temperature. To ensure the optimum quality of the welding, the heater plate must be cleaned before it. Any pimple cleaning must be done by soft cleaning materials using alcohol and so on. Heater plates (Teflon coating) should be damaged.

Pressures and forces of polyethylene welding fittings must match the instructions of the work machine that can be calculated or measured based on manufacturer information. The displacement pressure is taken from the indices of the welding machine during the slow movement of the welding part. This value should be added to the specified pressure. The movement pressure may change depending on the device, the diameter of the pipe and the length of the pipe. Therefore, before each welding process the movement pressure of the motion must be read and added to the connection pressure.

Gap width and inconsistency should be controlled and preventing distance and non -alignment as much as possible. Even in the worst conditions, the wall thickness should not exceed 1/10.

Buy and price of polyethylene welding fittings

The market is a database and network manufacturers and suppliers of construction products that introduce companies and examine specialized construction products. The overall goal of building the market is to communicate directly with the manufacturer. Dear buyers, they can go to the market construction system to find out the price of Polyethylene welding joints and buy from reputable sellers to buy polyethylene welding fittings.

Manufacturers and suppliers can register and with Putting the construction products and inserting the bid, in Special Sales Festival participate and sell Increase their products.
