BSD is a contemporary Kazakhstani diversified company with a highly professional engineering staff, which produces and markets Fire Hydrant Chambers, tanks, reservoirs, pump stations and water supply systems made of polyethylene HDPE PE100, designed for oil and gas branch, industrial, manufacturing, engineering and construction sectors.
BSD Company signed a memorandum with companies Krah, Germany and Krah Pipes, Estonia for production of products from polyethylene using Krah technology.
Production fully complies with European and American quality control standards and certified in the Republic of Kazakhstan, has ST KZ certificate and resolution of Kazakhstani Emergency Department for operation.
Specialists have been trained and certified in Germany and Estonia, qualified according to the Kazakhstan requirements for plastic welding.
BSD designs the engineering structures based on ground and groundwater loads, considering the natural peculiarities of the region where the product planned to install and operate. Company pays great attention on safety during production and high quality of the products, which has a warranty and service life for more than 100 years.
Production consists several stages
- Raw Material checks, that produced in the territory of the European Union approved and comply with US and Kazakhstani quality requirements.
- Preparation works:
Pre welding with hot air gun, using welding cable made of the same material and same polyethylene grade as a product that provides a monolithic structure of welds and weld joints. Welding carried out by welding equipment HSK and Leister extruders. During production all welds recorded in weld map and welding log, signed off by welders and filled Inspection and test plan, which signed off by Production manager, BSD Quality Control Inspector and appropriate and responsible persons from customer.
All heavy parts install using the hoist. Installation of all the other parts produced by hand. The entire manufacturing process performed according to assembly drawings approved by the customer, in compliance with the process. Manhole assembly produced according to the BSD designed drawings, using the technology of the sequence assembly of parts. Assembling and welding of the parts used manual method of extrusion welding. During welding, you can visually observe the changes in the surface structure of details. Extruder hot air fanned from the integrated feed system, which creates the necessary environment for the weld and heats the surface of the part to a small change in the structure of the interface. Prepared parts mating in the lower position must be installed on the same plane, fit tightly together to welded edges. Extruder during welding in the lower position should be kept at 90. Details for welding of fillet weld, abutting in angular position must be in relation to each other at the angle, e.g. 90.
Prefabricated parts mounted in the manholes, according to the customer approved drawings, taking into account all the nuances of the installation and the further installation at the construction site. Welding of the pressure pipes carried out on the equipment for the butt-welding according to the International HDPE welding Standard DVS. Butt-welded all joints are hydro tested under pressure. Within an hour every 15 minutes pipe is pressure tested for strength of butt welds and welding joints under visual control.
Complete manholes assembled by check valves, gate valves, flanges, hydrants, welded pressure pipes and ladders made of stainless steel AISI 316 with anti-slip surface on the stairs molded with nylon washers and nuts that prevent corrosion during further use and operation.
After production, every product tested for visual, dimension and hydro/leak tests in the presence of BSD Quality Control Inspector and Third Party Inspector or customer representative.
Upon successful completion of all tests and checks BSD specialist install electronic measuring instruments in the manholes, cleaned and prepared for shipping to the customer construction site, by BSD own machines according to TCO approved BSD shipping and handling procedure.
Products made of polyethylene are the most economical in the sphere of use, as it has a long service life, and not changeable for weather conditions and the environment. Products made of polyethylene can be installed underground, underwater, in all regions with specific environment and under any weather conditions.
The entire production cycle complies and approved by TCO requirements for safety and quality control. Each product accompanied by Passport, Certificate of original, welding documents, material certificates that is kept in the company for years.
