Haili Pipeline HDPE pipe manufacturer China

Septic Tank

Various types of pipe fittings are available in plumbing systems for different purposes and functions. A pipe fitting is used in plumbing system to join multiple pipes of same size or different sizes, to regulate the flow or to measure the flow.

HDPE pipe has strong corrosion resistance, does not need anti-corrosion treatment, saves cost, and the comprehensive economic benefit is 5-6 times that of steel pipe without excavation, and it is not easy to scale. It is suitable for underground transportation of media containing calcium, sulfur and magnesium ions.

HAILI’s pipe fittings production line include Piping Elbows, Piping Reducers, Tee Connections, Olet Connections, Caps, Crosses, etc. HAILI’s fitting have spread throughout East Asia, South Asia, South America, Middle East and Africa, and are the premium choice for local distributors and customers.

Inspection Chamber Manhole

PE inspection chamber can be divided into rainwater PE inspection chamber and sewage PE inspection chamber according to their uses. The application fields are divided into PE inspection chamber for building district drainage and PE inspection chamber for municipal drainage.

Most of the inspection part of the PE inspection chamber is a one-time injection molding, and the fittings such as reducing joints, variable angle joints and rubber sealing rings are used to achieve the connection of changing the pipe diameter and angle.

Compared with traditional brick, PE and PVC material inspection chamber, SMC inspection chamber are of stable quality, lighter weight, higher strength, superior sealing, waterproof performance and anti-corrosion performance. Meet the design needs of various projects.

The SMC inspection well produced by HAILI is easy to install, efficient in drainage, strong in bearing capacity, has a service life of 50-70 years, low maintenance costs, comprehensive cost, and has extremely excellent application space and market prospects.

Over the years, HAILI's products have spread throughout East Asia, South Asia, South America, Middle East and Africa, and are the premium choice for local distributors and customers.

PERT Heating Pipe

PE-RT II type pre-insulation pipe is composed of three layers of working pipe, thermal insulation layer and outer protective pipe.

PE-RT II type insulation pipeline adopts modern insulation technology.

The outer sheath is made of high-density polyethylene.

The middle layer of the pipe is a rigid polyurethane foam insulation layer.

Its inner working pipe is PERT II type heat-resistant polyethylene pipe, the diameter covers DN25 - 800mm.

PERT II type pipe has the characteristics of high-temperature resistance, corrosion resistance, scaling resistance and low flow resistance，which can be maintained in its long service life, so it is especially suitable for direct buried heating systems below 90°C.
